Having both myopia and farsightedness together refers to a condition where both near and distant vision are unclear, commonly occurring in people with myopia who begin to develop age-related presbyopia. Both myopia and farsightedness can be treated simultaneously with glasses, contact lenses, LASIK surgery, or intraocular lens implantation, depending on an ophthalmologist’s recommendation. The choice of treatment depends on vision prescription, age, corneal thickness, and professional advice from an ophthalmologist. Having both myopia and farsightedness simultaneously is a condition found in some adults, particularly when individuals with myopia begin to develop presbyopia. This causes abnormalities in both near and distance vision, affecting daily activities such as reading, working on screens, or driving. Understanding the causes and treatment options helps patients choose appropriate, safe, and effective eye care solutions.     What Does Having Both Myopia and Farsightedness Mean? Having both myopia and farsightedness means both near and distant vision become unclear. People who already have myopia may use glasses to improve distance vision, but when presbyopia develops with age, those same glasses may no longer provide clear near vision, requiring adjustments or new lenses.   In people with myopia, the issue is mainly due to the eye’s physical structure — either an elongated eyeball or an overly curved cornea — causing incoming light to focus in front of the retina. This results in blurred distance vision and often develops during childhood or adolescence.   Presbyopia, on the other hand, is unrelated to eyeball length. It is a natural age-related condition typically beginning after age 40. The crystalline lens inside the eye gradually loses elasticity and the focusing muscles weaken, reducing the eye’s ability to focus on near objects.   When both conditions occur together, the structural myopia remains unchanged while age-related lens stiffness develops concurrently.   This situation can be challenging: distance vision remains blurry due to existing myopia, while wearing myopic glasses may worsen near vision because the aging lens can no longer adjust focus effectively.   However, individuals with mild myopia (around -1.00 to -2.00 diopters) may sometimes read comfortably without glasses because their natural focal point aligns with reading distance. Once they wear myopic glasses again, near vision blur often returns.     Correction and Treatment Options Treatment focuses on ensuring incoming light accurately focuses on the retina. Options generally fall into three main categories:   1. External Vision Correction Devices Using external devices is a safe and easily adaptable option for those with both myopia and farsightedness.   Progressive Eyeglasses Progressive lenses are currently the most popular option and represent a modern standard for working adults. These seamless lenses gradually change prescription from top to bottom — distance correction at the top, intermediate vision in the middle (e.g., computer use), and near vision at the bottom.   The main advantage is clear vision at all distances without switching glasses. They also lack visible dividing lines, maintaining a youthful appearance. However, some users may need a short adaptation period.   Contact Lenses Multifocal contact lenses function similarly to progressive glasses, incorporating multiple prescriptions in a single lens. They often use concentric ring designs to support both near and distance vision.   The brain adapts by selecting the clearest image automatically. While convenient and glasses-free, sharpness may be slightly reduced compared with eyeglasses, particularly in low light, and adaptation may take time.   Another option is monovision, where one eye is corrected for distance (dominant eye) and the other for near vision. The brain combines both images for functional daily vision.   This approach is often more affordable than multifocal lenses but may slightly reduce depth perception, affecting night driving or 3D perception in some individuals.   A combined approach involves wearing myopia-correcting contact lenses for clear distance vision and using reading glasses only when needed. This provides excellent clarity at lower cost but does not eliminate glasses entirely.   Because fitting contact lenses for this condition is complex, professional evaluation by an ophthalmologist or optometrist is essential.   One drawback may be higher long-term costs and the need for careful lens hygiene.   2. Laser Vision Correction LASIK (Laser-Assisted in Situ Keratomileusis) permanently corrects refractive errors including vision prescriptions such as myopia, hyperopia, and astigmatism. The procedure involves creating a corneal flap, reshaping the cornea with laser energy, and repositioning the flap. Recovery is typically quick, with clearer vision often within 24–48 hours. Temporary dry eyes, glare, or halos at night may occur during adjustment.   It is suitable for individuals wanting to reduce reliance on glasses or contact lenses with adequate corneal thickness. Those with severe dry eyes, chronic eye disease, or unsuitable prescriptions may consider PRK or refractive lens exchange (RLE).   3. Intraocular Lens Implant Surgery RLE (Refractive Lens Exchange) involves replacing the natural lens with an artificial intraocular lens (IOL). It is suitable for individuals with significant combined myopia and farsightedness or presbyopia. Modern IOLs can correct multiple refractive errors simultaneously.     How to Choose the Right Treatment Selecting the best treatment depends not only on visual clarity needs but also on several factors:   Lifestyle and preferences: Glasses or contact lenses suit those avoiding surgery, while LASIK or RLE offer longer-term solutions. Overall eye health: Detailed eye examinations assess corneal thickness, retinal health, and other conditions to determine safe treatment. Cost considerations: Surgical treatments typically cost more upfront than glasses or contact lenses. Expected outcomes: Laser surgery may reduce but not always eliminate the need for reading glasses.     Why Choose LASER VISION Center at Bangkok Eye Hospital?

Here are common FAQs:   Can LASIK treat both myopia and farsightedness? Yes, LASIK can treat both conditions, but suitability depends on corneal thickness and eye health. Some patients may require alternative options such as intraocular lenses for optimal safety and results.   How should contact lenses be chosen? People with combined refractive errors may use multifocal or progressive contact lenses designed for multiple focusing distances. Consultation with an ophthalmologist or contact lens specialist is recommended for proper selection.   What are the symptoms? Symptoms include blurred near and distance vision. Individuals who previously used myopic glasses may find distance vision clear but struggle with reading or phone use due to presbyopia, requiring adjustments in eyewear.

Visual Freedom After 50 Refractive Lens Exchange (RLE): A surgical procedure that replaces the eye's aging natural lens with a high-tech artificial implant (IOL) to provide a permanent "visual reset." Ideal Candidates: Primarily individuals aged 50–55+ experiencing lens deterioration, presbyopia, or high refractive errors unsuitable for LASIK. Key Benefits: Restores clarity at all distances, improves quality of life, and ensures you will never develop cataracts in the future. Living in a vibrant city like Bangkok means being constantly on the move—whether you’re navigating the BTS, reading a menu at a rooftop bistro in Sukhumvit, or heading out for a weekend in Hua Hin. But if your vision is blurred by cataracts or the daily frustration of Presbyopia, these moments lose their spark. For many expats and international travelers, the constant cycle of fogged-up glasses in the humidity and the hassle of contact lenses in a tropical climate isn't just an inconvenience—it’s a barrier to enjoying life. Refractive Lens Exchange (RLE) provides a safe and effective solution tailored to each individual’s visual condition, restoring comfort and sharp focus to everyday life.   What Is Refractive Lens Exchange (RLE)? Refractive Lens Exchange (RLE) involves removing the natural crystalline lens—similar to cataract surgery—and replacing it with a customized Intraocular Lens (IOL). This procedure is designed to adjust the eye's refractive power and eliminate the need for glasses or contact lenses. For those over 50 whose lenses have begun to deteriorate or cloud, RLE offers a long-term solution that provides clarity at multiple distances. Is RLE Right for Your Age? Vision correction needs change as the eye matures. We categorize treatments based on the biological stage of your lens to ensure the best long-term outcome:   Ages 20 – 50 The natural lens is still flexible. We typically correct myopia or astigmatism using SMILE Pro® 2.0, NanoLASIK®, NanoRelex®, or possibly ICL (Implantable Lenses) for those with very thin corneas and cannot be corrected with LASIK options. Ages 50 – 55+ The lens becomes stiffer and cloudier. Laser treatments have limitations here. RLE is the superior choice, as it addresses both refractive errors and future cataract formation.   How the Natural Eye Lens Works The natural lens is located behind the iris and is transparent and flexible. In younger individuals, it adjusts focus easily. As age increases, the lens proteins begin to clump together and the lens loses flexibility. This leads to Presbyopia (difficulty with near vision) and eventually Cataracts, which cause blurred or foggy vision. Customizing Your Focus: IOL Technology Choosing your Intraocular Lens (IOL) is the most critical step in RLE. These lenses are calculated using advanced formulas based on your specific eye length and corneal curvature. Lens Type Key Advantages Best For... Monofocal Crisp distance vision; lowest chance of halos at night. Driving & TV (Reading glasses needed). EDOF Stretched range from far to intermediate. Computer work, cooking & dashboards. Trifocal Clear vision at Near, Mid, and Far distances. Total independence from glasses. Note on Monovision: We can also optimize your dominant eye for distance and your non-dominant eye for near vision using monofocal lenses. This "Monovision" approach reduces glasses dependency for those who adapt well to blended vision.   Refractive Lens Exchange Procedure   The Premium Choice: No-Blade RLE For patients seeking maximum precision, No-Blade RLE utilizes a computer-guided Femtosecond Laser. This laser pre-softens the lens, allowing for the use of minimal ultrasound energy (phacoemulsification), which leads to less inflammation and a faster visual recovery. What to Expect: Recovery & Adaptation After RLE, your brain undergoes neuro-adaptation as it adjusts to the new IOL. While basic activities can resume within 1–2 days, the brain typically takes 1 month to fully optimize close-range tasks, with night vision halos decreasing over 3–6 months.   Post-Operative Care Days 1–5 Rest eyes; use computers in short bursts; avoid dusty environments. Weeks 1–2 Avoid water contact in eyes; wear a protective shield while sleeping; use UV sunglasses. Month 1+ Resume full exercise; avoid rubbing the eyes; attend scheduled follow-ups. Precautions and Complications RLE uses the same proven method as cataract surgery. While risks like retinal detachment, infection, or lens misalignment are rare, they are manageable through our strict preoperative screening and specialist follow-up protocols.   Why Choose Our Specialists? We bridge world-class surgical precision with Thailand's hospitality. By utilizing the latest diagnostic biometry (like the IOLMaster 700), our internationally trained surgeons ensure your lens power is calculated with microscopic accuracy for the best possible lifestyle fit. Frequently Asked Questions (FAQ) How do I choose the right lens power? We use advanced formulas and preoperative measurements—corneal curvature, eye length, and intraocular parameters—to ensure the lens matches your specific visual needs. Will my vision change again in the future? No. The artificial IOL is permanent. It does not age or develop cataracts, providing stable vision for the long term. However, the natural lens capsule holding the IOL may become cloudy over time—a condition known as Posterior Capsular Opacification (PCO). While the artificial lens remains clear, this "secondary cataract" can blur your vision, but it is easily and permanently corrected with a 5-minute YAG laser procedure.

SMILE Pro is a flapless laser vision correction procedure for myopia and astigmatism.It requires only a 2–4 mm incision, allowing faster recovery and a lower risk of dry eyes compared with traditional LASIK.

The hallmark of this technology is its superior speed, precision, and patient comfort. It significantly reduces anxiety during the procedure and maximizes relaxation for the best possible outcome. How SMILE Pro Works SMILE Pro revolutionizes traditional LASIK by eliminating the need for a corneal flap. Instead, it uses a high-speed laser to create a lenticule (a small disc of tissue) inside the cornea according to the required vision correction (for myopia and astigmatism). The surgeon then removes this lenticule through a tiny 2-4 mm incision, permanently reshaping the cornea and resulting in clear vision. Who is SMILE Pro suitable for? SMILE Pro is suitable for individuals with nearsightedness and astigmatism who seek fast and safe results, specifically: Those who want to reduce their dependence on glasses or contact lenses due to daily activity inconveniences or occupational requirements. Active individuals, heavy screen users, or those concerned about flap complications since no flap means zero risk of flap dislocation, ensuring confidence post-surgery. Patients should be at least 18 years old with a stable prescription for at least 1 year. Vision can still change before the age of 18, so it is best to wait for stability for accurate and long-lasting results. No contraindications for LASIK, such as glaucoma, severe retinal diseases, or autoimmune diseases like SLE, as these may increase the risk of complications. Not recommended during pregnancy because hormonal changes can cause prescription fluctuations. It is advised to wait until after childbirth when hormones have stabilized. For those over 40, LASIK can restore distance vision, but due to age-related presbyopia (farsightedness), reading glasses may still be required occasionally.

We have compiled the answers for you. What is the difference between SMILE Pro and ReLEx SMILE? SMILE Pro differs from ReLEx SMILE primarily in laser speed. It reduces the laser time from 25–27 seconds to just 8–10 seconds, which minimizes the surgical duration and further reduces trauma to the eye. Does SMILE Pro surgery hurt? How long is the recovery? During the surgery, the doctor will apply anesthetic eye drops, so you will not feel any pain. You may only feel a slight pressure on your eye. Afterward, you might experience mild irritation similar to having dust in your eye for about 3–4 hours, which will gradually improve. Generally, the recovery time takes only 1-2 days before you can resume your normal daily activities. Is there a chance my vision will regress after SMILE Pro? SMILE Pro provides a permanent correction to your vision. However, in the long term, human vision can naturally change due to factors such as age, heavy eye usage, or certain eye diseases. Nevertheless, these changes are usually mild and are not considered a regression caused by surgical error. *Disclaimer: This information is for educational purposes only and cannot replace professional medical diagnosis.

KEY TAKEAWAYS LASIK technology in 2026 has advanced dramatically. The modern "micro-incision, flapless" approach significantly outperforms traditional methods for patients concerned about recovery times or long-term corneal structural integrity. SMILE pro® 2.0 represents today's leading standard, requiring just 8 seconds of laser runtime per eye. With a tiny incision of only 2–4 mm, most patients can seamlessly return to their daily routines the very next day. NanoRelex® stands out as a premium option for individuals with nearsightedness combined with astigmatism, leveraging real-time AI and OCT tracking to elevate surgical precision to unprecedented levels. LASIK in 2026: An Ophthalmologist’s Guide to Modern Vision Correction As an eye surgeon, I get asked about this constantly—especially recently, as headlines about "8-second LASIK" have started circulating. Patients naturally want to know: Is it true? Is a procedure that fast actually safe? That is why I want to break it down for you directly, physician to patient, to share exactly where vision correction technology stands today and what you need to know before making a decision. First, you can let go of old anxieties regarding blades, week-long recovery periods, or the risk of corneal flap displacement. The technologies we use today have moved far past those limitations.

Essential Pre-Screening Criteria ▶ Exclusive 2026 Promotions & Packages ▶ Frequently Asked Questions Traditional LASIK — Proven Results with Clear Limitations Before exploring the latest advancements, it is helpful to look back at the technologies that paved the way, so you can appreciate how far vision correction has evolved: Traditional LASIK: This method utilizes a specialized micro-blade called a microkeratome to create a "flap" on the corneal surface. The flap is lifted, an excimer laser reshapes the inner cornea, and the flap is replaced. While highly effective at correcting vision, it requires a relatively wide surgical incision. FemtoLASIK: This marked a massive evolutionary step. Instead of a mechanical blade, a Femtosecond laser is used to separate the corneal layers and create the flap. It dramatically increased precision, predictability, and safety over the traditional blade method. While both methods are safe and achieve excellent visual outcomes, they both share a reliance on creating a "corneal flap (Flap)." Because of this flap, patients must take extra precautions against accidental eye impacts, can experience temporary dry eyes during the initial recovery period, and require slightly more downtime compared to newer options. SMILE pro® 2.0: What It Is and Why It's a Game Changer Today, the gold standard rapidly growing in popularity is SMILE pro® 2.0, powered by the cutting-edge Carl ZEISS VisuMax 800 platform. The defining breakthrough here is that it is a entirely "flapless (No-flap)" procedure. The laser creates a microscopically thin piece of tissue called a "lenticule" inside the intact cornea. The surgeon then extracts this lenticule through a tiny micro-incision measuring just 2 to 4 mm. Why Patients Prefer This Approach: True 8-Second Laser Runtime: Yes, the rumors are true. The actual laser delivery takes only about 8 seconds per eye — making it roughly three times faster than previous generations. Patients are amazed at how quickly it is over, significantly lessening any procedural anxiety. Preserved Corneal Integrity: Because no flap is created, the anterior structural layers of the cornea remain completely intact. This leads to a marked reduction in post-operative dry eyes and eliminates any risk of flap displacement. Ideal for Active Lifestyles: If you play sports, swim, or lead a highly active life, this is the technique we recommend most. The eye retains maximum structural resilience. Ultra-Fast Recovery: Most patients enjoy significantly sharper vision by the very next morning, allowing them to return to work or regular activities within 1 to 2 days. Within the ophthalmic community, SMILE Pro 2.0 is highly regarded for treating myopia and astigmatism due to years of data proving its long-term accuracy, safety profile, and exceptional patient satisfaction rates. NanoRelex® — Precision Driven by Intraoperative AI Another incredible breakthrough worth noting is NanoRelex®, a Swiss-engineered technology engineered for absolute precision. What sets this technique apart is its use of Artificial Intelligence, which doesn't just help plan the surgery beforehand, but actively monitors the eye in real-time during the procedure. Ultra-Low Nanojoule Energy: It applies a remarkably low laser energy level compared to earlier systems, minimizing thermal impact and protecting surrounding corneal tissue. Real-Time Intraoperative OCT: The surgeon can visually track the corneal layers live via Optical Coherence Tomography as the laser operates. This real-time visualization provides an unmatched level of safety. High-Speed Eye-Tracking: An advanced tracking system monitors eye micro-movements continuously, allowing the system to compensate automatically for any subtle shifts. Minimal Incision: It shares the flapless advantages of a 2–3 mm micro-incision, ensuring a comfortable and fast healing process. In short, NanoRelex® is particularly exceptional for individuals with high astigmatism combined with myopia, or those whose unique corneal shapes demand an extraordinary level of mathematical precision. Are You a Candidate? Essential Pre-Screening Criteria While a definitive recommendation requires an in-person clinical exam, you are generally an excellent candidate for modern vision correction if you meet these baseline criteria: You are at least 18 years old. Your vision prescription has been stable for at least one year. Your corneal thickness falls within safe parameters (determined during your check-up). You have no underlying eye conditions (such as glaucoma or cataracts) or systemic health issues that could impair wound healing. If you meet these general criteria, the next step is a comprehensive eye evaluation. It is a quick, painless process that gives us the precise data needed to determine the best path forward for your eyes. Exclusive 2026 Promotions If you are ready to enjoy clear vision, we are currently running our special 2026 Eye Care Promotion for these advanced technologies.

Schedule Your Pre-LASIK Eye Assessment Call Center : 02-511-2111 Inquire via LINE 📅 Book Online Frequently Asked Questions Is it really just 8 seconds? Or is that marketing hype? It is completely real. The 8-second timeframe refers specifically to the active laser runtime of the Carl ZEISS VisuMax 800 platform used in SMILE Pro 2.0. This is a scientific fact, not a promotional exaggeration. By operating roughly three times faster than previous lasers, it dramatically cuts down the time you need to keep your eyes perfectly still, making the experience vastly more comfortable. How do SMILE pro® 2.0 and traditional LASIK compare in daily life? The differences you will actually notice come down to recovery speed and dry eye comfort. Traditional LASIK requires a wide flap incision, whereas SMILE Pro 2.0 uses a flapless micro-incision of just 2–4 mm. This significantly reduces temporary post-op dry eyes and completely eliminates the risk of flap displacement—making it the superior choice if you lead an active or athletic lifestyle. What makes the AI integration in NanoRelex® different from standard lasers? Standard lasers rely entirely on preoperative calculations. NanoRelex®, however, integrates real-time intraoperative OCT scanning directly into the surgical process. This lets the surgeon view a live cross-section of your corneal layers while the laser runs. Simultaneously, the AI tracks eye movements dynamically to micro-adjust precision, elevating safety and predictability—especially in complex cases. *Medical Disclaimer: This article is intended for educational purposes only and should not replace professional medical evaluation, diagnosis, or advice. To find out which procedure is safest and most suitable for your unique eyes, please schedule an in-person consultation with a qualified ophthalmologist.

There are several popular types of LASIK, such as PRK, which removes the corneal surface to reshape the cornea; LASIK, which uses a microkeratome blade to create a corneal flap; Femto LASIK, which uses a laser instead of a blade; and ReLEx SMILE, which involves a smaller incision and faster recovery. LASIK is suitable for people with nearsightedness, farsightedness, or astigmatism, who have a strong and sufficiently thick cornea, and no chronic or severe eye diseases. It is ideal for those who want to reduce their dependence on glasses or contact lenses in daily life. Choosing the most appropriate LASIK technique depends on your vision condition, corneal structure, and lifestyle. It’s best to consult an experienced ophthalmologist for a personalized evaluation and treatment recommendation. What Are the Different Types of LASIK? Vision problems such as nearsightedness, farsightedness, or astigmatism can significantly affect one’s quality of life. LASIK has become a popular and effective solution for permanent vision correction.Today, there are various LASIK technologies — each with its unique principles, advantages, limitations, and costs.This article explores how many types of LASIK there are, comparing each method’s pros and cons and helping you choose the best technique for your eye condition, budget, and lifestyle.   Main Types of LASIK Surgery LASIK technologies have evolved continuously to meet different vision correction needs. Each type works differently and has its own benefits and precautions:   1. PRK (Photorefractive Keratectomy) The earliest LASIK method. The surgeon removes the outer corneal surface before reshaping the cornea with a laser. The surface gradually regenerates.Pros: No risk of flap displacement; suitable for thin corneas or people with high-impact activities.Cons: Longer recovery (3–5 days of discomfort or blurred vision).   2. TransPRK An advanced form of PRK using Excimer laser to remove the epithelium and reshape the cornea in one step — without touching the eye directly.Pros: No flap creation; ideal for thin corneas.Cons: Similar recovery time to PRK; may cause temporary discomfort.   3. Standard LASIK Traditional LASIK using a microkeratome blade to create a corneal flap, then reshaping with a laser.Pros: Fast recovery, minimal pain.Cons: Possible flap displacement if the eye is hit within 1–3 months.   4. FemtoLASIK (Femtosecond LASIK) An upgraded version of standard LASIK using a Femtosecond laser instead of a blade to create the flap.Pros: More precise, safer, smoother flap surface, faster healing.Cons: Still carries minor flap displacement risk.   5. ReLEx SMILE Uses a Femtosecond laser to create a small tissue lenticule, which is removed through a 2–4 mm incision — no flap creation.Pros: Tiny incision, faster recovery, lower dry-eye risk, better corneal stability.Cons: Suitable only for myopia and astigmatism (not presbyopia).   6. SMILE Pro® The most advanced and comfortable LASIK technology today, using high-speed laser correction — only 8 seconds per eye.Pros: Fast, accurate, less anxiety during the procedure.Cons: Applicable for myopia and astigmatism only.   7. NanoLASIK An enhanced all-laser LASIK using low-energy femtosecond laser and AI-assisted scanning for higher precision.Pros: Painless, accurate, safe, effective for myopia, hyperopia, and astigmatism.   8. NanoReLEx® Uses next-gen femtosecond laser with AI + real-time OCT scanning, creating and removing corneal tissue via a small incision (~2 mm).Pros: Extremely precise, safest option, quick recovery.Cons: Suitable for myopia and astigmatism only.   9. NV LASIK Designed for presbyopia correction, using blended vision — one eye is corrected for distance, the other slightly nearsighted for near focus.Pros: Reduces dependency on reading glasses.Cons: Requires a short adaptation period.   10. Nano NV LASIK An advanced form of FemtoLASIK using ultra-fast femtosecond laser (nanojoule energy) for smooth corneal separation and rapid recovery.Pros: Enhances both near and distance vision for presbyopia; minimal discomfort.Cons: May slightly reduce contrast sensitivity.   Comparison Table: Types of LASIK Type Principle Advantages Precautions PRK Removes surface layer before reshaping cornea No flap, suitable for thin corneas Slower recovery, discomfort TransPRK Laser removes surface and reshapes in one step Touch-free, no flap Slower recovery Standard LASIK Blade creates flap, laser reshapes Fast recovery Flap may shift with impact FemtoLASIK Laser creates flap, no blade High precision, safer Minor flap risks ReLEx SMILE Laser creates small lenticule, removed via tiny incision Small incision, quick recovery Limited to myopia/astigmatism SMILE Pro® Fast femtosecond laser (8 sec/eye) Quick, comfortable Myopia/astigmatism only NanoLASIK Low-energy laser, AI precision Safe, accurate Slight risk if impacted early NanoReLEx® AI-assisted femtosecond laser, OCT scan Highly precise, safest Myopia/astigmatism only NV LASIK Blended vision correction See near & far Needs short adjustment Nano NV LASIK Nano-energy laser for presbyopia Fast recovery, smooth May reduce image sharpness   Who Is a Good Candidate for LASIK? LASIK is effective but not suitable for everyone. Ideal candidates should: Be 18 years or older Have stable vision for at least 1 year Have sufficient corneal thickness Have no severe eye diseases (e.g., glaucoma, cataracts) Have no uncontrolled medical conditions (e.g., diabetes)   Pre-LASIK Preparation Stop wearing contact lenses before surgery Wash your face and hair thoroughly Avoid makeup and wear front-button clothing Do not use perfume or deodorant sprays Avoid alcohol the day before Inform your doctor of all medications Do not drive on the day of surgery — have someone accompany you   Post-LASIK Care and Precautions Do not rub your eyes Avoid getting water in your eyes Do not swim or dive until cleared by your doctor Avoid eye makeup for at least 2 weeks Use prescribed eye drops strictly Wear protective eye shields while sleeping for 1 week Rest your eyes regularly when using screens   How Much Does LASIK Cost? Costs vary by technology. A comprehensive eye evaluation at Bangkok Eye Hospital can help determine the most suitable technique and estimate the total cost, including aftercare and insurance options.   Conclusion How many types of LASIK are there?There are several — such as PRK, LASIK, Femto LASIK, and ReLEx SMILE, each differing in technology, incision size, and recovery time.Choosing the right LASIK method requires professional evaluation to ensure safety, accuracy, and long-term results.Bangkok Eye Hospital offers modern technology and specialized eye care to help you achieve clearer vision confidently.   FAQs About LASIK Types 1. Can I undergo another LASIK procedure with a different technique?Yes, but it depends on your corneal condition and previous method. For example, if you previously had LASIK with a flap, your surgeon may reopen it for enhancement. PRK retreatment is also possible for certain cases.   2. Does the LASIK type affect recovery time?Yes. PRK typically takes several days to a week for recovery, while LASIK, Femto LASIK, and ReLEx SMILE allow clear vision within 1–3 days.   3. Which LASIK technique is best for me?It depends on your vision type, corneal thickness, lifestyle, and budget. Consulting a specialized ophthalmologist is essential for finding the most suitable and effective option.
