Bumrungrad Congratulates Prof. Koonlawee Nademanee, M.D., Honored as Asia’s First Pioneer in Cardiac Pacing and Electrophysiology
Bumrungrad International Hospital proudly congratulates Prof. Koonlawee Nademanee, M.D., Director of the Bumrungrad Heart Institute and specialist in cardiac electrophysiology, on being honored with the Pioneer in Cardiac Pacing and Electrophysiology Award 2026 by the Heart Rhythm Society (HRS). This prestigious recognition marks an important milestone, as Prof. Koonlawee becomes the first recipient from Asia to receive this international award. The congratulatory ceremony was led by Artirat Charukitpipat, Ph.D., Chief Executive Officer of Bumrungrad International Hospital, together with Assoc. Prof. Taveesin Tanprayoon, MD, Chief Medical Officer. They were joined by a team of physicians and hospital executives in celebrating Prof. Koonlawee’s remarkable achievement and his long-standing contribution to the field of heart rhythm care. Cardiac electrophysiology is a specialized field of cardiology that focuses on the heart’s electrical system, which controls the rhythm and timing of each heartbeat. When this system does not function normally, patients may experience arrhythmias, or irregular heart rhythms, which can affect quality of life and, in some cases, become serious. Advances in cardiac pacing and electrophysiology have helped improve the diagnosis and treatment of many heart rhythm disorders.
The Heart Rhythm Society is a leading international organization in cardiac electrophysiology. It supports education, research, and clinical resources that help physicians provide evidence-based care and improve patient outcomes worldwide. The Pioneer in Cardiac Pacing and Electrophysiology Award recognizes individuals whose original and innovative work has made significant contributions to this highly specialized field.
Prof. Dr. Koonlawee’s recognition reflects not only his dedication as a physician and researcher, but also the growing role of Asian medical expertise on the global stage. For Bumrungrad International Hospital, this honor reinforces its commitment to advancing complex cardiac care, supporting medical excellence, and providing patients with access to internationally recognized specialists and world-class heart care.

Eye Evaluation and Checkup: A Guide to Healthy Vision Clear vision supports daily life, from learning and working to moving safely and connecting with others. Since many eye problems develop quietly, regular eye evaluations help protect vision, detect concerns early, and support eye health at every age.
A comprehensive eye checkup may include:
Regular eye evaluations can help detect common and complex conditions, including:
Visual acuity testing to assess how clearly you see
Nearsightedness, farsightedness, and astigmatism Dry eye and eye strain Cataracts Glaucoma Retinal disease Eye complications related to systemic diseases such as diabetes or high blood pressure Eyelid problems such as tumors or infections
Refraction testing to determine whether glasses or contact lenses are needed Eye pressure measurement to screen for glaucoma risk Pupil response and eye movement assessment Slit-lamp examination to evaluate the structures at the front of the eye Retinal examination to evaluate the back of the eye Specialized tests when needed for specific symptoms or conditions
Adults should also seek medical attention for sudden vision changes, eye pain, flashes of light, new floaters, double vision, persistent redness, or difficulty seeing at night.
Children also need eye checkups, even when they do not complain about vision problems. Young children may not realize that their vision is unclear, and some eye conditions are easier to treat when detected early.
A child’s eye evaluation may include checks for: Pupil response Eye movement Lazy eye Misaligned eyes General eye health Visual acuity Color vision Three-dimensional vision
Recommended eye checkups for children include:
First eye examination between 3 and 6 months of age
Does not focus well on objects Has an abnormal reflection or white spot in the pupil Appears to have a lazy or misaligned eye Has excessive tearing, redness, or chronic discharge Squints, moves closer to objects, or holds objects too close to their eyes to see clearly Has a family history of eye problems Parents should seek an eye evaluation promptly if a child:
Second eye examination at around 3 years of age
Third eye examination between 5 and 6 years of age
At Bumrungrad International Hospital’s Eye Excellence Center , specialized ophthalmologists provide eye examinations, diagnosis, consultation, and treatment for patients of all ages, from general eye concerns to complex and emergency conditions.

Dr. Nattawut Wanumkarng:
Helping Patients Restore Natural Eye Function and Confidence
Nattawut Wanumkarng, M.D., is an ophthalmologist specializing in comprehensive ophthalmology, oculoplastic, and reconstructive eye surgery. He earned his medical degree from the Faculty of Medicine Siriraj Hospital, Mahidol University, and is certified by the Thai Board of Ophthalmology. He completed fellowship training in orbital and ophthalmic plastic and reconstructive surgery at the University of California, San Diego. His clinical expertise includes functional and cosmetic eyelid surgery, lacrimal surgery, orbital tumors, thyroid eye disease surgery, and reconstruction after eyelid or orbital trauma. With advanced surgical training, he helps patients restore eye function, comfort, appearance, and confidence through personalized, safety-focused care. Q Q When do “tired eyes” become more than a cosmetic concern?
When should watery eyes be checked by an eye specialist?
“Tired eyes” may be more than a cosmetic issue when drooping eyelids begin to affect vision, comfort, or daily activities. Some patients may notice that their upper eyelids feel heavy, that they need to raise their eyebrows to see clearly, or that they have difficulty reading, driving, or working for long periods. In these cases, eyelid surgery is not only about appearance. It can help improve the field of vision, reduce eye fatigue, and support a more natural, refreshed look.
Watery eyes should be checked when tearing is frequent, persistent, or interferes with daily life. Some people constantly wipe their eyes or feel embarrassed because their eyes look as if they are crying. This may be caused by blocked tear drainage, eyelid position problems, irritation, or other eye conditions. An eye specialist can identify the cause and recommend appropriate treatment. In some cases, lacrimal surgery may help restore proper tear drainage and reduce chronic watering.
Q
After an accident or injury near the eye, what can reconstructive surgery help restore?
Injury around the eye can affect more than appearance. It may involve the eyelids, tear ducts, eye socket, muscles, or surrounding tissues. Reconstructive surgery aims to restore eye protection, eyelid movement, facial balance, and comfort while preserving vision as much as possible. The goal is to help patients recover function and return to daily life with greater confidence.

Clearer Vision, Greater Freedom:
on Refractive Surgery Dr. Tharinee Kulkamthorn
Tharinee Kulkamthorn, M.D., is an ophthalmologist specializing in comprehensive ophthalmology and refractive surgery. She earned her medical degree from the Faculty of Medicine Ramathibodi Hospital, Mahidol University, and is certified by the Thai Board of Ophthalmology. She completed fellowship training in cornea at Chulalongkorn Hospital, followed by advanced fellowship training in cornea, external diseases, and refractive surgery at the Shiley Eye Center, University of California, San Diego. With a special clinical interest in refractive surgery, Dr. Tharinee helps patients explore safe, personalized options to reduce dependence on glasses or contact lenses and improve everyday visual confidence.
Q Why do some people choose refractive surgery instead of continuing with glasses or contact lenses? Many people consider refractive surgery because they want clearer vision with greater freedom in daily life. Glasses can fog, slip, break, or feel inconvenient during sports, travel, swimming, or outdoor activities. Contact lenses may also cause dryness, irritation, infection risk, or discomfort, especially for people who wear them for long hours or work in air-conditioned environments. Refractive surgery, including options such as LASIK and ReLEx SMILE, aims to correct common vision problems such as nearsightedness, farsightedness, and astigmatism. For suitable patients, it can reduce dependence on glasses or contact lenses and make daily routines more comfortable.
Q
Is refractive surgery suitable for everyone?
Refractive surgery is not suitable for every patient. A detailed eye examination is essential before treatment. The ophthalmologist will assess visual power, corneal shape and thickness, tear film quality, eye surface health, pupil size, and overall eye condition. Age, lifestyle, occupation, hobbies, and expectations are also important. This careful evaluation helps determine whether the patient is a good candidate and which procedure may be safest and most appropriate.
Q
What should patients understand before deciding on refractive surgery?
Patients should understand that refractive surgery is a personalized medical procedure, not a one-size-fits-all solution. Each option has different benefits, limitations, recovery expectations, and suitability. The goal is not only good vision, but also long-term safety, comfort, and quality of vision. A consultation helps patients understand realistic outcomes and make a confident, informed decision.

Dry Eye Disease: Causes, Symptoms, and Relief for Modern Eyes Dry eye disease is one of the most common eye concerns in modern life. It can affect office workers, students, contact lens wearers, travelers, and anyone who spends long hours in air-conditioned spaces or in front of digital screens. While it may seem minor, dry eye can interfere with reading, working, driving, and daily comfort if it is not properly managed. Dry eye happens when the eyes do not produce enough tears, or when tears evaporate too quickly. A healthy tear film protects the eye surface, keeps vision clear, and helps prevent irritation.
Several everyday factors can contribute to dry eye, including:
Common symptoms may include:
Prolonged screen time, which reduces blinking
Dry, gritty, or sandy feeling in the eyes
Watery eyes
Air-conditioned rooms, which can increase tear evaporation
Sensitivity to light
Poor screen position or glare
Burning, stinging, or itching
Indoor dust, allergens, and pollution
Contact lens use
Redness or eye fatigue
Meibomian gland dysfunction, when the small oil-producing glands inside the eyelids become blocked or inflamed
Blurred vision that comes and goes, especially after screen use
Simple habits can help reduce discomfort:
At Bumrungrad International Hospital, the Dry Eye Clinic provides evaluation and personalized care for people with ongoing dry eye symptoms. Treatment may include artificial tears, prescription medication, punctal plugs, intense pulsed light therapy, or eyelid hygiene treatment, also known as Eyelid Spa.
Follow the 20-20-20 rule by looking 20 feet away for 20 seconds every 20 minutes
Blink regularly, especially while using screens
Adjust screen height and lighting to reduce eye strain
Eyelid Spa may include:
Drink enough water throughout the day
Warm compresses
Eyelid massage
Use a humidifier in very dry rooms
Careful eyelid cleaning to help open blocked glands, reduce inflammation, and improve tear film quality
Use artificial tears if recommended
With the right diagnosis, daily care, and specialist-guided treatment, dry eye disease can often be managed effectively, helping your eyes feel more comfortable and your vision stay clearer throughout the day.

Advanced Dry Eye Care with IDRA Diagnosis and LLLT Treatment
When dry eye symptoms continue despite simple lifestyle changes, artificial tears, or eyelid care, a more detailed evaluation may be needed. Dry eye is not the same for every person. Some patients have reduced tear production, while others have tears that evaporate too quickly because the oil-producing glands in the eyelids are not working properly. This is why advanced diagnosis plays an important role in choosing the right treatment.
IDRA is an advanced, non-invasive dry eye diagnostic system. It does not treat dry eye directly. It helps ophthalmologists analyze the tear film and eyelid oil glands to understand what type of dry eye a patient has and what may be causing it.
For dry eye evaluation, IDRA can assess:
Tear film stability Tear volume
Tear composition Lipid layer quality Meibomian gland structure and function Tear evaporation patterns
Low-Level Light Therapy, or LLLT , is one advanced treatment option for patients with dry eye related to meibomian gland dysfunction. LLLT uses gentle light energy around the eyelid area to support meibomian gland function, help improve the quality of the oil layer in the tear film, and reduce inflammation that may contribute to dryness and irritation. This detailed information allows ophthalmologists to better understand what is causing the dryness. For example, if the test shows poor lipid layer quality or blocked meibomian glands, the patient may have evaporative dry eye, which often requires treatment focused on improving gland function rather than using eye drops alone.

LLLT may be recommended to help:
Improve tear film quality Support healthier oil flow from the eyelid glands Reduce eyelid inflammation Relieve dryness, burning, and irritation Improve comfort during

Meibomian gland dysfunction, or MGD , occurs when the small oil glands inside the eyelids become blocked or do not work properly. Without enough healthy oil in the tear film, tears evaporate too quickly, leading to evaporative dry eye.
screen use, reading, or contact lens wear
Together, IDRA and LLLT offer a more targeted approach to dry eye care at the Dry Eye Clinic at Bumrungrad International Hospital. IDRA helps identify the cause, while LLLT helps address one of the common underlying problems: poor meibomian gland function. With the right diagnosis and treatment plan, dry eye care can become more precise, personalized, and effective.

Eat for Your Eyes: Eyes: How Nutrition Helps Support Better Vision Good vision depends on more than eye checkups, glasses, and screen habits. A balanced diet also helps nourish the eyes, protect delicate tissues, and support healthy vision as we age. Certain nutrients are especially important for the eyes. Vitamin A supports the surface of the eye and helps with vision in low light. Lutein and zeaxanthin, found in green leafy vegetables, are concentrated in the retina and help protect the macula, the part of the eye responsible for sharp central vision. Vitamins C and E act as antioxidants, helping protect eye cells from everyday damage. Zinc supports the retina, while omega-3 fatty acids may help support tear quality and eye comfort, especially for people prone to dry eyes.
Eye-friendly foods include:
Green leafy vegetables: Spinach, kale, collard greens, and other dark greens contain lutein and zeaxanthin. Orange and yellow fruits and vegetables: Carrots, pumpkin, sweet potatoes, and mangoes provide vitamin A and other nutrients.
Fatty fish: Salmon, sardines, and tuna are sources of omega-3 fatty acids.
Eggs: Eggs contain lutein, zeaxanthin, and other nutrients that support eye health.
Nuts, seeds, and beans: These foods provide vitamin E, zinc, and plant-based nutrients.
Nutrition is also closely linked to overall health conditions that can affect the eyes. For example, managing blood sugar, blood pressure, and cholesterol through healthy eating may help reduce the risk of eye complications related to diabetes, hypertension, and cardiovascular disease. A practical approach is to choose colorful, whole foods every day and limit highly processed foods, excessive sugar, and unhealthy fats. Staying well hydrated can also support general eye comfort.
Citrus fruits and berries: Oranges, grapefruits, strawber- ries, and blueberries are rich in vitamin C.
At Bumrungrad International Hospital’s Eye Excellence Center, eye care focuses on prevention, early detection, diagnosis, and treatment for patients of all ages. Combined with regular eye evaluations, a healthy diet is one simple daily habit that can help protect your vision for the future.

What Your Microbiome May Reveal Dry Eye and the Gut:
Dry eye is usually discussed as a problem of the tear film, eyelids, screen habits, contact lenses, aging, or dry environments. Today, researchers are also paying closer attention to a less obvious connection: the gut microbiome. The gut microbiome is the community of bacteria and other microorganisms living in the digestive system. These microorganisms help the body digest food, produce useful compounds, support immune balance, and regulate inflammation. Because the immune system influences many parts of the body, an imbalance in the gut may have effects beyond digestion. This is where the gut-eye connection becomes interesting. The surface of the eye is delicate and depends on a stable tear film, healthy eyelids, and balanced inflammation. When the gut microbiome becomes disrupted, sometimes called gut dysbiosis, the body may become more prone to inflammatory responses. Emerging studies suggest this may play a role in ocular surface health, including dry eye disease.
This does not mean that gut health alone causes dry eye, or that probiotics or diet changes can replace eye treatment. Dry eye is a multifactorial condition, which means several factors may contribute at the same time. However, digestive health may be one part of the wider picture, especially for people with recurring dryness, autoimmune conditions, allergies, or chronic inflammation.
Daily habits that may support both gut and eye health include:
Managing allergies,
Eating a balanced diet with vegetables, fruits, whole
Drinking enough water throughout the day
autoimmune conditions, or chronic health concerns with medical guidance
Taking regular breaks from screens
Getting consistent sleep
grains, and healthy fats
At Bumrungrad , patients with persistent dry eye can receive a detailed eye evaluation to identify possible causes and guide appropriate care. Depending on each patient’s needs, treatment may include tear support, eyelid care, lifestyle advice, or advanced therapies.
The gut-eye connection is still an evolving area of science, but it highlights an important message: healthy eyes may be supported by caring for the body as a whole.

Leading with Clarity, Balance, and Care: A Conversation with Pornsuree Konanta, Vice President, Corporate Affairs at Chevron Thailand Exploration and Production, Ltd.
How does your organization embed well-being into its culture? Well-being becomes meaningful through everyday leadership behavior. We prioritize physical and psychological safety, encouraging people to speak up, share ideas, and raise concerns. We also consider workload, recovery, and flexibility while maintaining accountability. When people feel safe, respected, and able to sustain their energy, trust and performance strengthen each other. In high-pressure environments, how do you sustain clarity and resilience? I return to purpose, values, and priorities. I focus on calm decision-making, transparent communication, and listening to diverse perspectives. Personally, resilience comes from rest, reflection, and balance. When leaders remain grounded, their teams feel steadier. What experience most transformed your approach to leading people? Experience taught me that meaningful leadership must be sustainable. Inspired by the Middle Path, I try to lead with moderation, avoid extremes, and respond thoughtfully rather than reactively. This helps me support people with greater balance and perspective. What insight would you share with the next generation of global leaders? Cultivate adaptability, self-awareness, humility, and empathy. Professional skills matter, but health, relationships, integrity, and resilience sustain leadership over time. Leadership is measured not only by achievement, but by the ability to lead consistently, ethically, and with care.
Which defining moments shaped your journey as a leader?
How would you describe your leadership philosophy in today’s complex world? I believe a leader’s role is to make work simpler, not harder, for others. My philosophy is grounded in clarity, simplification, and care. By setting clear priorities, making consistent decisions, and removing unnecessary complexity, leaders create an environment where people can focus, contribute, and perform at their best. What health and wellness trends will redefine corporate performance? Corporate performance is driven by people. Preventive health and mental well-being are becoming essential because they directly influence judgment, collaboration, energy, and resilience. Organizations that invest intentionally in employee well-being will be better equipped to manage long-term complexity and achieve sustainable results. My leadership journey has been shaped more by transition than by title. Moving from the public sector into a global energy company required me to adapt to greater speed, complexity, and scale. With support from leaders and colleagues, I learned that leadership means helping people navigate change with confidence, clarity, and respect.

Leading Transformation with Purpose: The Leadership Journey of Anusara Suthikulavet, CEO of UBE Group (Thailand)
My career began in engineering, followed by more than 35 years in sales and marketing. It taught me to view business through the customer’s perspective, anticipate market changes, and understand what people need. At UBE Group (Thailand), I am helping lead the transformation from a production-driven organization to a market-driven, customer-centric specialty chemical business. Transformation is never one person’s achievement. I set the direction and communicate a vision, while our people bring it to life daily. UBE Group’s vision has always been about finding the right people with the right mindset, regardless of gender. To future women leaders, I would say: Rising into leadership often means carrying responsibilities on multiple fronts, and I believe that this quietly builds resilience and empathy that are not easily taught. Do not wait until you feel completely ready. Step forward, build trust, and let your results speak. Gender is becoming less of a barrier to how far you can go.
As UBE Group (Thailand)’s first female CEO, what shaped your leadership journey, and what would
you share with future women leaders?
How does UBE Group (Thailand) support employee wellbeing? Employee wellbeing is part of our culture. We provide health and accident insurance, outpatient coverage, annual health checkups, and on-site first-aid facilities. Our preventive health initiatives include education on noncommunicable diseases, body composition assessments, cancer screening, mental health support, and office syndrome prevention. Through the UGT FIT Challenge, an internal program in which employees log various types of physical activity and healthy eating habits, they compete for real rewards. When colleagues start encouraging each other, this creates energy and helps them develop healthier habits through friendly competition. How do you stay healthy and balanced? After experiencing office syndrome earlier in my career, I made exercise non-negotiable. I exercise for one hour every morning and walk in the evening when possible. I also meditate during my commute, eat a balanced breakfast, and complete an annual health checkup. Most importantly, I focus on what I can control. I give each situation my best thinking in the moment, learn from it, and then let it go. This mindset helps me remain clear, balanced, and ready to show up fully the next day.
What role should businesses play in sustainability and the circular economy? Sustainability is not a trend. In the chemical industry, it is a responsibility. We follow UBE Group’s global direction on reducing environmental impact, using resources responsibly, and advancing the circular economy. Our Thailand operations have reduced greenhouse gas emissions by more than 90% compared with 2013. We are targeting zero plastic waste to landfill and aim to sell more than 10,000 metric tons of circular economy products by 2030. We rank in the top 25% on a global sustainability platform and aim to reach the top 5% by 2030.

Common Myths About Eye Drops
Eye drops may look simple, but they are highly specific products. Different formulas are designed for different eye concerns, and using the wrong drops can irritate the eyes, mask symptoms, or delay proper treatment. Eye drops should be used based on need, not habit.
Myth 1
Myth 2
Once opened, eye drops can be used any time
All eye drops are safe
Not all eye drops are meant for regular use. Some redness-relief drops contain vasoconstrictors, which temporarily narrow blood vessels on the eye surface to make the eyes look less red. However, in people with narrow eye drainage angles, these drops may dilate the pupils and block fluid drain- age, causing eye pressure to rise dangerously. Redness-relief drops are for short-term use only. If redness continues, returns often, or is linked with eye pain or vision changes, see an ophthalmologist.
Eye drops should not be used indefinitely after opening. Bottles, tips, and solutions can become contaminated, especially if the dropper touches the eye, eyelashes, hands, or any surface. Some eye drops also need to be stored in a cool place or under specific conditions. Always check the label for the discard date and storage instructions, replace the cap after use, and avoid sharing eye drops with others.
Myth 3
Myth 4
Preservatives in eye drops do not matter
Lubricating drops may provide temporary comfort, but they do not cure the underlying cause of dry eye. Severe, constant, or recurring dryness should be checked by an ophthalmologist rather than managed only with basic drops. Over-the-counter drops can cure dry eye
Preservatives help prevent bacterial growth in multi-use bottles, but they can irritate the eyes if drops are used frequently. People who need artificial tears more than four times a day may benefit from preserva- tive-free formulations.
At Bumrungrad Eye Excellence Center , ophthalmologists can identify the cause of eye symptoms and recommend safe, appropriate treatment. Bumrungrad pharmacists also play an important role by clearly explaining how prescribed eye drops should be used and stored, helping patients use their medication correctly and safely.

Digital screens are part of daily life, from work and meetings to homework, gaming, and entertainment. However, long hours of close-up screen use can affect eye comfort. Digital eye strain, also called computer vision syndrome, may occur when the eyes work intensely for extended periods and is often linked to everyday habits. Digital Eye Strain and Modern Lifestyle : How Daily Habits Affect Eye Health
Common discomfort may include:
Common contributing factors include:
Reduced blinking Poor lighting Screen glare
Tired eyes Dryness or irritation Blurred vision Headaches Neck and shoulder tension
Incorrect viewing distance Continuous near-focus tasks
Modern lifestyle habits can make symptoms more noticeable. Air-conditioned rooms may dry the eye surface. Working late on devices may disturb sleep quality. Looking at a phone very close to the face can place extra demand on the focusing system of the eyes. Contact lens wear, uncorrected vision problems, and dry eye disease may also make screen-related discomfort worse.
Healthier screen habits may include:
Children need special attention because they may not always explain eye discomfort clearly. Instead, parents may notice changes in behavior.
Possible signs in children include:
Taking regular eye breaks during screen or reading time
Keeping screens at a comfortable distance
Reducing glare and adjusting room lighting
Rubbing the eyes often Blinking frequently
Holding devices too close Losing interest in reading Complaining of headaches Difficulty seeing the board at school Extended screen time may also reduce outdoor activity, which is important for children’s visual development and overall health.
Encouraging children to spend more time outdoors
Avoiding screens close to bedtime
Having regular eye checkups, especially if symptoms persist
Digital devices are part of modern life, but ongoing eye discomfort should not be ignored. If eye strain, dryness, blurred vision, headaches, or changes in a child’s visual behavior continue, an eye examination can help identify the cause. At Bumrungrad Eye Excellence Center, ophthalmologists provide comprehensive eye evaluations for adults and children.

I never imagined that at the age of 60 , I could see as clearly as I did when I was 30 .
Khun Wannaporn Malaithong’s Experience with Cataract Treatment and Surgery
“
As a business owner running an online business, I spend much of each day using a computer and smartphone. Over time, my eyes became irritated, and my vision gradually blurred. When these problems began affecting both my work and daily life, I decided to consult an eye specialist.
“
What impressed me most was Bumrungrad’s wide range of intraocular lens options. I could choose a lens that matched my daily activities, which gave me confidence in my decision and future vision. To obtain accurate measurements and support the best possible surgical outcome, we treated the dry eye disease first. Once it was well controlled, we performed detailed measurements and calculations for the intraocular lens, or IOL. We then discussed the available lens options and selected the one that best suited her lifestyle and visual needs.” Dr. Nattawut Wanumkarng explained: “When Ms. Wannaporn came to us, her main concerns were blurred vision and chronic eye irritation. A comprehensive examination revealed cataracts and significant dry eye disease, with approximately 70–80% tear gland dysfunction. “
“
The process begins with precise preoperative measurements and IOL calculations. During surgery, we use the ORA (Optiwave Refractive Analysis) System to verify lens power in real time. This additional measurement helps us select an appropriate lens and achieve results that closely match each patient’s expectations and visual goals.
Dr. Maytinee Sirimaharaj added: “At Bumrungrad International Hospital, experienced ophthalmologists, dedicated nurses, and advanced diagnostic and surgical technology support comprehensive cataract care.
After cataract surgery and lens replacement, many patients say they feel as though they have turned back the clock to their early 30s. They can enjoy the activities they love with renewed confidence and ease.
Cataracts are treatable. Cataract surgery is generally safe, effective, and virtually painless. Do not delay seeking medical advice. The earlier cataracts are assessed and treated when appropriate, the sooner patients may regain clearer vision and improve their quality of life.”

Brings Free Healthcare to Ban Khrua Community Bumrungrad Volunteer Mobile Medical Unit
The Bumrungrad Hospital Foundation , in collaboration with Bumrungrad International Hospital, continued its commitment to community health through the Bumrungrad Volunteer Mobile Medical Unit 3/2026. The outreach activity was held on Thursday, 25 June 2026, at Yamiul Khoiriyah Mosque, also known as Surao Kong Asa Cham , in the historic Ban Khrua community. Ban Khrua is one of Bangkok’s oldest Muslim communities, with roots dating back to the reign of King Rama I. By bringing medical services directly into the neighborhood, the initiative aimed to make essential healthcare more accessible while strengthening relationships with local residents. A team of eight specialist physicians from several medical disciplines volunteered their time and expertise to provide free consultations and health screenings. The participating specialties included internal medicine, pediatric cardiology, orthopaedics, and dentistry. Community members had the opportunity to discuss health concerns, receive professional medical advice, and undergo basic assessments designed to identify potential health risks.
The event was supported by a multidisciplinary team of more than 50 healthcare professionals and volunteers. Nurses, pharmacists, physical therapists, and volunteer staff worked closely with the physicians to coordinate patient care, provide medication guidance, assist with physical health assessments, and help ensure that each participant received attentive, well-organized support. The collaborative approach reflected Bumrungrad’s focus on patient-centered care, where different healthcare professionals work together to address the needs of each individual. In addition to medical consultations, the outreach encouraged greater awareness of preventive care and the importance of seeking medical attention when symptoms or health concerns arise. The Bumrungrad Volunteer Mobile Medical Unit is part of the Bumrungrad Hospital Foundation’s continuing efforts to support underserved communities and improve access to quality healthcare. Through the dedication of its medical teams, healthcare professionals, and volunteers, the program helps bring practical health support closer to people while reinforcing a shared commitment to community well-being.

Are Your Eyes Telling You Something About Your Health? Most people think of eye health in terms of vision. We schedule eye examinations when our eyesight changes or when reading becomes more difficult. However, our eyes may reveal much more than how well we see. They can provide valuable clues about overall health and the way our bodies age. The eyes are unique because they are one of the few places in the body where blood vessels and nerve tissue can be observed directly. This means that changes within the eye may reflect changes occurring elsewhere in the body. Eye health can be linked to conditions such as diabetes, high blood pressure, cardiovascular disease, and cognitive decline. The retina, located at the back of the eye, is considered an extension of the central nervous system. Because of this close connection, scientists are studying how retinal changes may help identify early signs of brain aging and neurological health concerns. The eyes offer a glimpse into what may be happening beneath the surface before symptoms become noticeable. Nutrition plays an important role in maintaining healthy vision throughout life. Micronutrients such as vitamin A, vitamin C, vitamin E, zinc, omega-3 fatty acids, lutein, and zeaxanthin help protect the eyes from oxidative stress and support healthy retinal function. These nutrients are also important for brain health, immune function, cellular repair, and healthy aging. At VitalLife Scientific Wellness Center , maintaining long-term health begins with understanding the body’s unique needs. Through comprehensive health assessments, advanced biomarker analysis, and Micronutrient Testing, our physicians can identify nutritional deficiencies and other underlying factors that may affect overall well-being. By combining scientific insights with personalized recommendations, we help individuals take a proactive approach to optimizing their health before problems arise.
In the era of preventive and longevity medicine, eye health is about more than preserving vision. It is an opportunity to gain deeper insights into the body’s condition, identify potential risks earlier, and make informed choices that support healthy aging. Sometimes, the path to a healthier future begins by paying closer attention to what your eyes may be telling you.
