Dry eyes Tears play a crucial role in keeping our eyes moist, ensuring clear vision by letting light effectively pass through the eye's lens, and supplying oxygen to nourish the eye. They also help fend off infections and keep foreign substances at bay.   Now, when it comes to dry eyes, it's a pretty common issue that can stem from abnormal tear production or tears evaporating too quickly. This can lead to discomfort, irritation, that feeling like there's something foreign in your eye, redness, pain, blurry vision that gets better with blinking, or even feeling like your eyes are tired and heavy. What causes dry eyes can vary—getting older, being a woman (yeah, we're more prone to it), certain allergy medications, spending loads of time on screens, being in places with dust and smoke, gusty winds, and bright lights, they can all have a hand in it.   But hey, the good news is there are ways to tackle dry eyes:   Keep away from things that can make it worse, like strong winds and dust, by popping on some sunglasses and protecting those peepers. Remember to take breaks or blink more often, especially when you're glued to screens for a while. You've got these cool eye drops called artificial tears. There's a type for daytime (more watery) and nighttime (a bit thicker). Which one to use depends on how serious your dry eye situation is. Sometimes your doc might suggest special eye drops that encourage your eyes to make more tears. Give your eyes a treat with warm, clean cloths over your closed eyelids to help them feel better. If the dry eye struggle is real and isn't improving, it's wise to chat with an eye doctor.   All in all, dry eyes can be a bother, but there are solutions out there. It's important to take good care of your eyes, especially when it's all dry outside. If you suspect you've got dry eyes, having a chat with an eye care expert is a smart move.      

Can You Become Nearsighted Again After LASIK? It is possible to become nearsighted again after LASIK if your vision was not yet stable before the surgery or due to a condition called regression.Common causes include natural changes in vision, individual healing responses, unstable vision prior to surgery, high myopia, or underlying health conditions. When nearsightedness returns after LASIK, possible treatments include enhancement surgery (re-LASIK) if the cornea is thick enough, wearing glasses or contact lenses, or in some cases, considering ICL (Implantable Collamer Lens) implantation as an alternative. Many people who experience vision regression after LASIK may feel disappointed — especially after initially enjoying clear vision. This situation often raises concerns and questions such as: Why did my vision change? Do I need another LASIK? Are there other options?This article explores the possible causes of recurrent myopia after LASIK, the available solutions, and key things to know before deciding on further treatment. Can You Become Nearsighted Again After LASIK? Recurrence of nearsightedness after LASIK is uncommon and usually not serious.Think of it like a healing wound — each person heals differently, even from an identical cut. Similarly, the corneal healing process varies from person to person. In most cases, patients do not experience significant regression. However, for individuals with very high myopia (over -8.00 D) or high astigmatism (over 2.00 D), a mild degree of myopia may return over time — typically around -1.00 D within ten years. This slight regression rarely affects daily life and often still provides better vision than before surgery with glasses. Interestingly, mild nearsightedness that reappears after the age of 40 can even be beneficial, as it helps with near vision (e.g., reading or using a phone) without relying heavily on reading glasses.In general, LASIK results are long-lasting, though natural changes in vision due to aging may still occur over time. Why Can Vision Become Nearsighted Again After LASIK? Regression after LASIK does not necessarily mean the surgery failed. It can occur due to several factors that influence visual stability: 1. Natural Changes in Vision If LASIK is performed before vision stabilizes, refractive changes may continue afterward.This is especially common in younger patients or those with ongoing vision changes.For this reason, doctors typically recommend waiting until vision has been stable for at least 1–2 years before undergoing LASIK. 2. Individual Healing Response Each person’s cornea heals differently. Some may develop epithelial hyperplasia (overgrowth of corneal cells) or subtle biomechanical changes that alter corneal curvature, leading to mild regression. Healing patterns and tissue responses are highly individual. 3. Inaccurate Preoperative Assessment If the initial measurement or laser calibration was slightly off, the correction may not be perfect, leading to residual myopia later.Accurate preoperative evaluation is therefore crucial to ensure precise and lasting outcomes. 4. Severe Myopia Before Surgery Patients with very high myopia require more corneal tissue removal during LASIK, which can increase the likelihood of long-term regression.In such cases, alternative procedures like PRK or ICL implantation may be more suitable to ensure safety and long-term stability. 5. Other Contributing Factors Additional factors that may influence post-LASIK vision include: Pregnancy or breastfeeding, due to hormonal changes that affect vision Chronic diseases such as diabetes with poor sugar control Certain medications, such as corticosteroids or antidepressants, which can impact visual stability How to Care for Your Eyes After LASIK Proper post-operative care is essential to maintain long-term vision results and prevent regression. Below are key recommendations: First Night After LASIK Get adequate rest but avoid touching or rubbing the eyes. Use protective eye shields as instructed by your doctor and do not remove them unless advised. If tears accumulate, gently blot around the shield without touching the eyes. Avoid washing your face with water; use a clean cloth instead. You may shower and brush your teeth, but keep water away from your eyes. First Week After LASIK Use prescribed antibiotic drops and artificial tears as directed. Always wear the protective eye shield when sleeping. Avoid getting dust or water in the eyes and refrain from rubbing them. Avoid makeup around the eyes for at least two weeks. Wear sunglasses outdoors to reduce glare and dryness. After one week, your doctor will usually allow normal face washing and hair washing. Swimming is typically safe after two weeks. What Are the Treatment Options If Myopia Returns After LASIK? If regression occurs, an ophthalmologist will conduct a thorough evaluation to identify the cause and recommend the most suitable approach: Glasses or Contact Lenses The simplest and safest option for mild regression. It avoids surgical risks and allows easy adjustment as vision changes over time. Re-LASIK (Enhancement) If the cornea remains sufficiently thick and healthy, an enhancement LASIK can be performed.The surgeon reopens or recreates the flap and uses a laser to fine-tune the correction.However, additional LASIK carries risks such as increased dryness or corneal thinning, so detailed evaluation is essential. PRK (Photorefractive Keratectomy) Recommended for patients with thin corneas or when flap re-lifting is not feasible.PRK removes the corneal surface directly, but recovery takes longer and may involve temporary discomfort. ICL (Implantable Collamer Lens) An alternative for those with very high myopia or thin corneas.A specialized lens is implanted inside the eye to correct vision without reshaping the cornea.It is a more complex and costly procedure but can be a safe and effective long-term solution. Summary While LASIK is highly effective in correcting nearsightedness, mild regression can occur due to natural eye changes or individual healing differences.Accurate preoperative assessment and advanced surgical technology are key to achieving precise, lasting results. Bangkok Eye Hospital uses cutting-edge equipment and experienced specialists to ensure safe, reliable outcomes and minimize the risk of vision regression — delivering lasting clarity and confidence to every patient. Frequently Asked Questions (FAQ) Is repeat LASIK safe?Yes, enhancement LASIK is generally safe if the cornea is thick enough and the doctor confirms suitability. When should I see a doctor if my vision worsens again?If you notice blurred vision or your eyesight seems to revert to pre-LASIK levels, consult a refractive surgery specialist promptly. Can I prevent vision regression after LASIK?While not always preventable, you can reduce the risk by ensuring your vision is stable for 1–2 years before surgery, choosing an experienced surgeon and reputable facility, and following all postoperative care instructions — including adequate rest and avoiding excessive eye strain.

What Are Contact Lenses? Contact lenses are clear lenses worn directly on the eyes to correct vision problems or enhance appearance. They come in many types, such as soft lenses, rigid gas-permeable (RGP) lenses, daily or monthly lenses, toric lenses for astigmatism, and cosmetic color lenses. Proper contact lens care includes washing hands thoroughly before handling lenses, cleaning them with contact lens solution after every use, avoiding tap water or saliva, storing them in fresh solution daily, and cleaning the lens case regularly—replacing it every 3 months to prevent eye infections. When wearing contact lenses, follow your eye doctor’s instructions, avoid sharing lenses, always wash your hands before touching them, and do not wear them for too long or sleep with them in to reduce the risk of irritation and infection. Contact lenses are a great option for people who want clear vision or a more striking look. However, improper use or poor hygiene can cause serious eye problems. Therefore, it’s important to know how to wear, clean, and care for them correctly to ensure long-term eye health and safety. What Are Contact Lenses? Contact lenses are thin, transparent discs placed on the cornea to correct refractive errors—conditions where light entering the eye does not focus properly on the retina, resulting in blurred vision. They can correct nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia (age-related farsightedness). Types of Contact Lenses Contact lenses can be categorized based on material and duration of use. 1. Rigid Contact Lenses Rigid Gas-Permeable (RGP) lenses allow oxygen to pass through to the cornea. They are ideal for people with high astigmatism or keratoconus, helping reshape the cornea for sharper vision. 2. Soft Contact Lenses Soft lenses are the most popular type due to their comfort and ease of use. They include: Daily lenses: Single-use lenses discarded after one day; hygienic and low infection risk. Weekly lenses: Worn daily and replaced every 1–2 weeks. Monthly lenses: Worn daily and replaced every month. Extended-wear lenses: Can be worn overnight for several days, but with high infection risk—use only under medical advice. Toric lenses: Correct astigmatism; available in daily and extended-wear forms. Color lenses: Available for vision correction or cosmetic purposes; includes fashion lenses, big-eye lenses, UV-blocking, and color vision correction lenses. Always consult an ophthalmologist before use. Cosmetic lenses: Used purely for appearance—such as cat-eye or vampire effects. Even without vision correction, they should be prescribed by an eye doctor to prevent infections. 3. Other Specialized Lenses Hybrid lenses: Combine soft and rigid materials to improve comfort and visual clarity; ideal for irregular corneas or aging eyes. Multifocal lenses: Contain multiple vision zones for both near and far focus; suitable for presbyopia. Therapeutic lenses: Used after eye surgery to protect and promote corneal healing. Benefits of Contact Lenses Provide clear, natural vision without restricting peripheral view, unlike eyeglasses. Convenient for sports or active lifestyles. Enhance appearance and confidence, especially with cosmetic color options. How to Insert Contact Lenses Wash hands thoroughly with soap and water; dry with a lint-free towel. Work on a clean surface; close sink drains if working near water. Start with the same eye every time (e.g., right eye first). Rinse lens with solution—never use tap water. Place the lens on your fingertip and check that it’s not inside out (edges should curve upward like a bowl). Hold upper eyelid with one hand and lower eyelid with the other. Look straight ahead and gently place the lens on the eye. Blink slowly to center it. Repeat for the other eye. How to Remove Contact Lenses Wash and dry your hands first. Look up and gently pull down your lower eyelid. Slide the lens down onto the white part of the eye. Pinch it gently between your thumb and index finger to remove. Clean with lens solution before storing. Replace daily lenses with a new pair as instructed. Proper Lens Care and Storage Clean lenses daily with recommended solution. Rub lenses gently with fingertips to remove residue. Replace the solution in the case every day. Clean and air-dry the lens case weekly; replace every 3 months. Never rinse lenses with tap water, saline, or saliva. Avoid transferring lens solution into smaller containers. Discard expired or old solution. Who Should Avoid Wearing Contact Lenses Avoid wearing lenses if you have: Dry eyes or corneal abnormalities Skin conditions around the eyelids Thyroid eye disease (protruding eyes) Poorly controlled diabetes Allergies to lens materials or cleaning solutions Tremors, hand coordination problems, or skin issues on fingers/nails Safe Contact Lens Practices Get lenses fitted by an eye specialist. Wash and dry hands before touching lenses. Do not share or swap lenses. Avoid swimming or sleeping with lenses on. Keep solution bottle tips clean. Wear sunglasses outdoors to reduce light sensitivity. Use artificial tears to relieve dryness. Risks of Improper Contact Lens Use Using lenses incorrectly or unhygienically can cause: Dry eyes: From prolonged wear or low tear production. Allergic reactions: From lens materials or cleaning agents. Conjunctivitis (Eye inflammation): Often from allergies or bacteria. Corneal abrasions or ulcers: Caused by dryness, poor hygiene, or tight lenses. Corneal hypoxia: Oxygen deprivation due to extended wear, leading to swelling or infection. Microbial keratitis: Bacterial infection causing redness, pain, and blurred vision—often from sleeping in lenses. Summary Contact lenses offer a convenient and effective way to correct vision and enhance appearance, with various types such as daily, monthly, and color lenses. However, improper use and poor hygiene can lead to eye infections, dryness, and inflammation. Always clean lenses properly, replace solutions regularly, and consult an ophthalmologist if you experience discomfort or redness. For safe eye care and expert consultation, visit Bangkok Eye Hospital, where our specialists can help ensure your eyes remain healthy and protected. Frequently Asked Questions (FAQ) 1. Is it safe to wear contact lenses for more than 8 hours?It’s best not to wear contact lenses longer than 8–9 hours a day. Extended wear can cause dryness, irritation, and inflammation. Use artificial tears to keep eyes moist if wearing them for longer periods. 2. Do contact lenses thin the cornea?Wearing lenses doesn’t directly affect corneal thickness. However, prolonged use may cause dryness or irritation. Stopping use allows eyes to recover moisture, but corneal thickness remains unchanged. 3. What happens if I sleep with my contact lenses on?Sleeping in lenses limits oxygen flow to the cornea, especially when eyelids are closed. This increases the risk of redness, irritation, and infection. Always remove lenses before sleeping unless specifically prescribed for overnight wear.

What Is Retinal Vascular Occlusion? Retinal vascular occlusion is a condition that occurs when one of the blood vessels carrying blood to or from the retina becomes blocked. This interruption in blood flow can lead to sudden vision loss and may result in permanent damage if not treated promptly. There are two main types: Central Retinal Artery Occlusion (CRAO): A blockage in the main artery supplying the retina Central Retinal Vein Occlusion (CRVO): A blockage in the main vein draining blood from the retina There are also branch occlusions, affecting smaller vessels: Branch Retinal Artery Occlusion (BRAO) Branch Retinal Vein Occlusion (BRVO) These are considered ocular emergencies, particularly CRAO, which is sometimes likened to a “stroke in the eye.” Causes of Retinal Blood Vessel Blockage The causes can vary depending on whether the artery or vein is affected, but most cases are related to underlying systemic vascular diseases. Common Causes Include: Atherosclerosis (hardening of arteries) Hypertension (high blood pressure) Diabetes mellitus High cholesterol levels Blood clotting disorders Heart disease and arrhythmias Inflammatory vascular conditions Smoking and sedentary lifestyle Glaucoma (increases the risk of vein occlusion) In rare cases, an embolism from the heart or carotid artery can travel and lodge in the retinal vessels. Symptoms to Watch For Symptoms can vary depending on the type and severity of occlusion: Arterial Occlusion (CRAO/BRAO) Sudden, painless, severe vision loss in one eye Vision may be reduced to light perception only Occasionally preceded by transient vision loss (amaurosis fugax) Venous Occlusion (CRVO/BRVO) Blurry or distorted vision Gradual or sudden vision changes Dark spots or floaters In some cases, eye pain due to increased eye pressure These symptoms are ocular emergencies and require urgent care to minimize permanent vision loss. Diagnosis at Bangkok Eye Hospital At Bangkok Eye Hospital, timely diagnosis and assessment are critical. Diagnostic procedures include: Dilated fundus examination to visualize blood flow and retinal health Optical Coherence Tomography (OCT) to detect retinal swelling or fluid accumulation Fluorescein angiography to assess blood circulation in the retina Ultrasound (B-scan) if there is significant hemorrhage Blood tests and cardiovascular screening to investigate underlying systemic conditions Carotid artery ultrasound and echocardiography, if embolism is suspected Early intervention improves outcomes, particularly in CRAO cases where treatment within hours is most effective. Treatment Options for Retinal Vascular Occlusion There is no single cure, but various treatment options aim to restore circulation, reduce swelling, and prevent further vision loss. For Artery Occlusion (CRAO/BRAO) Immediate ocular massage and breathing into a paper bag to increase CO₂ and dilate vessels Reducing intraocular pressure using medication or anterior chamber paracentesis Hyperbaric oxygen therapy in select cases Management of cardiovascular risk factors and antiplatelet therapy Unfortunately, recovery is limited if treatment is delayed beyond a few hours. For Vein Occlusion (CRVO/BRVO) Intravitreal injections of anti-VEGF drugs (e.g., ranibizumab, aflibercept) to reduce macular edema Intravitreal steroids for inflammation and swelling Laser photocoagulation to treat neovascularization or ischemic areas Ongoing monitoring to prevent complications such as neovascular glaucoma Treatment is usually ongoing and requires regular follow-ups. Complications of Retinal Vascular Occlusion If untreated, vascular occlusion can lead to: Permanent vision loss Macular edema Neovascularization (abnormal vessel growth) Glaucoma (due to increased pressure) Retinal hemorrhage or detachment Managing systemic conditions such as hypertension and diabetes is crucial to prevent recurrence. Prevention and Risk Management Maintain healthy blood pressure and cholesterol levels Manage blood sugar in diabetic patients Stop smoking Exercise regularly and follow a balanced diet Attend regular eye exams, especially if you have cardiovascular risk factors Take prescribed blood thinners or antiplatelet drugs under medical supervision Early detection of changes in the eye’s blood vessels can reduce the risk of future blockages.

CRAO is often referred to as an "eye stroke" and is an emergency requiring immediate medical attention. Can vision be restored after an occlusion?Partial recovery is possible, especially in vein occlusions. Arterial occlusions have a narrow treatment window for recovery. What’s the difference between CRAO and CRVO?CRAO involves an artery supplying blood to the retina, while CRVO involves a vein draining blood away. Symptoms and treatment differ. Who is most at risk for retinal vascular occlusion?People over age 50 with high blood pressure, diabetes, high cholesterol, or heart disease are at higher risk. How can I prevent future occlusions?By managing systemic health conditions, quitting smoking, and having regular eye exams to monitor eye and vascular health.

What Does It Mean When Your Eyes Are Yellow? Yellowing of the eyes — whether in the sclera (white of the eye) or as yellow discharge (eye mucus) — is not a condition in itself but a visible symptom that can signal a range of underlying health issues, from minor eye infections to serious systemic diseases like liver dysfunction or biliary disorders. Understanding what causes yellowing in or around the eyes is essential to determining when to seek medical attention and what treatment is needed. Yellowing of the Sclera (Yellow Eye Whites) When the whites of your eyes turn yellow, this is medically referred to as scleral icterus. It usually indicates a buildup of bilirubin, a yellow pigment produced during the normal breakdown of red blood cells. Common Causes: Liver diseaseSuch as hepatitis, cirrhosis, or fatty liver disease Gallbladder or bile duct obstructionIncluding gallstones or tumors blocking bile flow Hemolytic anemiaRapid breakdown of red blood cells leading to bilirubin overload Pancreatic diseaseConditions that interfere with bile drainage Alcohol-related liver damage Newborn jaundiceTemporary condition in infants due to immature liver function This yellowing of the eyes often appears alongside jaundice in the skin and may be accompanied by other symptoms such as fatigue, dark urine, or abdominal pain. Yellow Eye Discharge (Yellow Mucus in Eyes) Unlike scleral yellowing, yellow discharge from the eyes is typically a sign of an ocular infection or inflammation. It may appear as crust around the eyes in the morning or sticky mucus during the day. Common Causes: Bacterial conjunctivitis (pink eye)Characterized by thick yellow or green discharge, redness, and irritation BlepharitisChronic eyelid inflammation leading to yellowish crusting Blocked tear duct (especially in infants)Causes fluid and mucus to accumulate KeratitisInfection of the cornea, may include pain, blurred vision, or light sensitivity Eye injuriesResulting in secondary infection or discharge Allergic conjunctivitisUsually produces clear discharge, but can mix with mucus and bacteria If yellow discharge is persistent or associated with pain, swelling, or blurred vision, it should be assessed by an eye doctor. When to Worry About Yellow Eyes You should seek urgent medical evaluation if: Both eyes show sudden yellowing Yellowing is accompanied by jaundice or dark urine Yellow discharge is thick and persistent You experience eye pain, light sensitivity, or vision changes You have a history of liver disease or substance use Early detection of systemic or ocular conditions can prevent serious complications, including vision loss or organ damage. Diagnosis at Bangkok Eye Hospital At Bangkok Eye Hospital, we provide a comprehensive evaluation to determine the cause of yellow eyes or discharge. Diagnosis may include: Slit-lamp eye examination to assess the cornea, conjunctiva, and discharge Tear duct assessment in infants or adults with chronic discharge Liver function blood tests (AST, ALT, bilirubin) if scleral icterus is present Ultrasound or imaging of the liver and biliary tract if indicated Conjunctival swab or culture for infection detection We also work closely with internal medicine or hepatology specialists when liver disease is suspected. Treatment Options Treatment depends on the underlying cause: For Yellow Sclera (Systemic Cause): Liver disease management: Includes antiviral therapy, alcohol cessation, or liver support Gallstones or biliary obstruction: May require surgical removal or stenting Dietary changes: For fatty liver or metabolic conditions Medical management: For autoimmune liver conditions or genetic disorders For Yellow Eye Discharge (Ocular Cause): Antibiotic eye drops or ointments: For bacterial conjunctivitis or keratitis Warm compresses and lid hygiene: For blepharitis or mild discharge Tear duct massage or minor surgery: For blocked tear ducts Steroid drops (under supervision): For severe inflammation Lubricating drops: For dry eyes or irritation-related discharge How to Prevent Eye Discoloration or Discharge Maintain good hand and facial hygiene Avoid sharing towels, cosmetics, or eye drops Treat systemic conditions such as diabetes or liver disease promptly Wear protective eyewear in dusty or hazardous environments Use contact lenses properly and cleanly Regular eye exams can also detect early signs of systemic illness and protect your vision.

Yellow sclera usually indicates elevated bilirubin levels, commonly from liver or bile duct issues. Can an eye infection cause yellow discharge without redness?Usually, yellow discharge is associated with some degree of redness or irritation, but mild cases may not be obvious. Can I treat yellow eye discharge at home?Mild cases may improve with warm compresses and eyelid cleaning, but antibiotics may be necessary for bacterial infections. Is yellow eye discharge contagious?If caused by bacterial or viral conjunctivitis, yes — it can be contagious through contact with secretions.   Can newborns have yellow eyes or discharge?Yes. Newborn jaundice is common and usually temporary. Yellow discharge can result from a blocked tear duct, which often resolves over time but may require treatment.
