SMILE Pro is the latest laser vision correction surgery that doesn’t require a flap, minimizing eye trauma and enabling faster recovery. It’s ideal for people with heavy physical activity or intensive visual use. SMILE Pro uses a high-speed laser to create a tiny lenticule inside the cornea, which is then removed through a small 2–4 mm incision without opening a flap. This reduces impact on the eye and allows for rapid healing. It’s suitable for those looking to reduce dependence on glasses or contact lenses, especially active individuals, heavy visual users, or those concerned about traditional LASIK flap wounds. For people seeking a permanent solution for nearsightedness, farsightedness, or astigmatism, SMILE Pro is a popular choice. The advanced laser technology ensures precision, minimal incisions, fast recovery, and reduced risk of complications—perfect for modern patients who want safe and effective long-term results. What is SMILE Pro? SMILE Pro® is the latest advancement from ReLEx SMILE technology, offering superior speed, precision, and comfort. It uses the Carl ZEISS VisuMax 800 laser, which corrects vision in just 8 seconds per eye, reducing anxiety during the procedure and enhancing patient relaxation.   How SMILE Pro Works SMILE Pro revolutionizes traditional LASIK by eliminating the need for a corneal flap. The high-speed laser creates a lenticule inside the cornea according to the required prescription. The surgeon then removes the lenticule through a small 2 mm incision, permanently reshaping the cornea and improving vision clarity.   Who is SMILE Pro For? SMILE Pro is ideal for people with myopia or astigmatism seeking fast, safe results, including: Those who want to reduce dependence on glasses or contact lenses due to daily activities or work demands. Active individuals or heavy visual users concerned about flap complications, as no flap is created. Patients aged 18 or older with stable vision for at least one year. Individuals without contraindications such as glaucoma, retinal disorders, or autoimmune eye diseases. Not recommended during pregnancy due to hormonal changes affecting vision stability. Patients over 40 may still need reading glasses due to presbyopia.   Where to Get SMILE Pro SMILE Pro is offered at Laser Vision, Bangkok Eye Hospital, providing: The latest VisuMax 800 technology for precise, fast laser correction.

SMILE Pro provides permanent correction, but natural age-related changes or eye conditions may alter vision slightly. Regression due to surgery error is rare.

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.
