What is LASIK and How It Improves Vision
Designed by Freepik
LASIK (Laser-In Situ Keratomileusis) is one of the most common types of laser eye surgery in Thailand. It corrects vision problems such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism by reshaping the cornea with a laser.
✅The goal is to let light focus correctly on the retina for sharper vision without glasses or contact lenses.
Why it’s trusted:
-
LASIK has been used worldwide for over 20 years and has a strong safety record.
-
Studies show LASIK delivers stable, predictable results, with about 95% of patients achieving clear vision.
-
In Thailand, clinics follow the same international standards for LASIK eye surgery used in Europe and the United States.
The Medical Council of Thailand licenses doctors who perform LASIK in Thailand, and many hold memberships in the Asia-Pacific Academy of Ophthalmology or the American Academy of Ophthalmology. These memberships ensure ongoing training and knowledge of the latest refractive techniques.
Who Can Benefit from LASIK Eye Surgery
Before performing Laser-assisted vision correction, the doctor will carefully assess whether the procedure is safe and effective for the patient.
People are usually suitable if they:
-
Are between 18 and 45 years old and have a stable prescription for at least one year.
-
Have myopia, hyperopia, or astigmatism within the treatable range.
-
Have healthy and sufficiently thick corneas.
-
Do not have severe eye conditions such as glaucoma, cataract, or severe dry eye.
-
Are not pregnant or breastfeeding.
-
Understand that LASIK reduces dependence on glasses but does not guarantee perfect vision for life.
LASIK may not be suitable for people who have:
-
Thin or irregular corneas.
-
Uncontrolled diabetes or autoimmune diseases.
-
Chronic eye inflammation or dryness.
-
Professions or activities with a high risk of eye injury (for example, combat sports).
✅ Before surgery, Thai ophthalmologists perform a detailed preoperative assessment, which includes:
-
Corneal topography to map the shape of the cornea.
-
Pachymetry to measure corneal thickness.
-
Tear film testing to detect dryness.
-
Refraction and pupil analysis to check prescription stability and night vision potential.
Why So Many Patients Choose Thailand for Eye Care
Thailand is one of Asia’s most trusted destinations for laser eye surgery and LASIK, attracting around 3 million international patients each year seeking high-quality care, advanced technology, and reasonable prices.
💡Thailand’s ophthalmic sector is rapidly developing — the national ophthalmic supply market is projected to grow at a CAGR of about 7.7%, reaching USD 465.9 million by 2030. This steady growth supports wider access to advanced laser technology, such as excimer and femtosecond lasers, used in refractive laser procedures across Bangkok, Phuket, and Chiang Mai.

Types of Refractive Surgery and What to Expect
Patients considering laser eye surgery in Thailand want clear vision without glasses, but aren’t sure which method is best for them. Thailand offers several types of refractive surgery to correct nearsightedness, farsightedness, and astigmatism, using precise excimer and femtosecond lasers at top clinics.
| Procedure | Core technique | Typical recovery | Outcomes | Notes |
| LASIK / laser in situ keratomileusis | Create a thin corneal flap, reshape tissue with excimer laser. | Functional vision in 24–48h. | ~90% end up between 20/20 and 20/40 unaided; a 2016 analysis reported ~99.5% 20/40+. | Fast recovery; enhancement may be needed if the prescription regresses. |
| Femto-LASIK (bladeless) | Flap created with a femtosecond laser, then excimer reshape. | 24–48h. | Visual results comparable to LASIK; some studies report fewer early dry-eye symptoms vs blade flaps. | “Bladeless” flap creation can aid precision and centration. |
| SMILE / ReLEx SMILE | No flap; small incision removes a lenticule. | 48–72h. | Visual acuity comparable to femto-LASIK at 12 months; less dry eye in first 6 months. | Suitable for active patients; no corneal flap. |
| PRK | Surface treatment (no flap); epithelium removed, excimer laser reshape. | ~5–7 days to functional; weeks to full. | 99.5% of eyes with 20/40 vision or better at 12 months, ~7% retreatment rate, stable outcomes over 1 year. | Preferred if the cornea is thin or irregular; slower early recovery. |
❗A comprehensive eye examination (corneal topography/pachymetry, tear-film tests, refraction, pupil size) identifies the safest surgical procedure for each case of refractive surgery.
Pre-Surgery Evaluation and Eye Health Checks
Before the surgery, patients undergo a comprehensive eye examination to confirm safety and select the right refractive surgery method.
💡These checks help detect hidden eye diseases and ensure the cornea can be safely reshaped with a laser.
| Test | Purpose |
| Corneal topography | Maps the cornea’s surface to detect irregularities or early corneal diseases. |
| Pachymetry | Measures corneal thickness to confirm it’s safe to create a corneal flap. |
| Refraction test | Confirms the stability of myopia, hyperopia, or astigmatism before correction. |
| Tear-film test | Checks for dry eyes and determines if prescribed eye drops are needed. |
| Pupil and retina exam | Evaluates overall eye health and rules out conditions such as glaucoma. |
| Health and medication review | Identifies factors (such as isotretinoin acne medications) that may affect healing. |
❗Before testing, patients are advised to avoid contact lenses for several days to ensure accurate measurements.
Step-by-Step: From Consultation to Clear Vision
The entire procedure usually takes about 15 minutes per eye. Vision often improves immediately and continues to clear during the next few days.
Step-by-step process:
-
Preparation – The ophthalmologist applies anesthetic drops. The patient remains awake but comfortable.
-
Creating the corneal flap – A thin corneal flap is made using either a microkeratome or a femtosecond laser, depending on the technology chosen.
-
Reshaping the cornea – An excimer laser gently reshapes the corneal tissue to correct refractive errors such as myopia, hyperopia, or astigmatism.
-
Flap replacement – The flap is carefully repositioned; it naturally seals without stitches.
✅ The entire laser eye surgery process is computer-guided for precision and usually painless. Vision often improves within hours, but stabilization continues for several days.
Healing and Returning to Daily Life After LASIK
Most patients notice improved vision within the first day, though minor fluctuations are normal.
| Timeframe | What Happens |
| Immediately after surgery | Mild burning or tearing may occur; protective shields are used overnight. Severe pain is uncommon. |
| First 24 hours | Vision becomes clearer but may still blur at times. Patients use prescribed eye drops to prevent infection and dryness. |
| 1–3 days | Return to work and everyday tasks are usually possible, but patients should avoid strenuous activities, eye makeup, and swimming. |
| 1 week | First post-operative check-up confirms corneal healing. |
| 1 month | Vision typically stabilizes; most patients achieve clear sight without glasses or contact lenses. |
❗During healing, doctors recommend avoiding eye rubbing, dust, and bright sunlight. Artificial tears can reduce dry eyes. The doctor will provide personalized aftercare instructions based on each patient’s specific needs.
Balancing Safety and Expectations
Thai laser vision improvement surgery in Thailand is generally very safe. For suitable candidates, the satisfaction rate exceeds 97.4%. Complications are rare, and most side effects are mild and temporary.
Still, patients should be aware of possible risks:
-
Dry eyes or mild irritation for one to two weeks.
-
Glare, halos, or light sensitivity, especially at night during recovery.
-
Slight under- or over-correction, occasionally requiring enhancement surgery.
-
Sporadic cases of infection or issues with the corneal flap.
-
Natural changes in vision or eye health over time, unrelated to the procedure.
💚 Clinics verified through Bookimed follow strict safety standards and provide transparent complication rates, giving patients peace of mind and access to follow-up support if needed.
Finding the Right Thai Eye Clinic
Choosing the right clinic is simple if patients focus on verified quality and transparency.
