What is Laser Eye Surgery?
Laser eye surgery is one of the most popular elective procedures worldwide. It uses precisely controlled laser energy to reshape the cornea — the clear front surface of the eye — correcting how light is focused onto the retina.
The result is sharper vision without the need for glasses or contact lenses. Modern techniques like LASIK, SMILE, and PRK each take a slightly different approach, but all aim to correct common refractive errors including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
With over 25 years of refinement, laser eye surgery has an excellent safety profile and satisfaction rates above 95%.
Techniques & Approaches
LASIK
A thin flap is created in the cornea, the underlying tissue is reshaped with an excimer laser, and the flap is replaced. The most widely performed laser vision correction.
SMILE
A femtosecond laser creates a small lenticule inside the cornea, which is removed through a tiny incision. Minimally invasive with fast recovery.
PRK / LASEK
The surface epithelium is removed and the cornea is reshaped directly. Preferred for thin corneas or patients not suitable for LASIK.
TransPRK
An advanced no-touch surface ablation technique where both epithelium removal and correction are performed by the laser in a single step.
Benefits
- Quick recovery — most patients see clearly within 24 hours
- Painless procedure with numbing eye drops
- 95%+ patient satisfaction rate
- Freedom from glasses and contact lenses
- Long-lasting results — often permanent
- Quick procedure — typically 15-30 minutes for both eyes
Ideal Candidate
Best suited for patients aged 20-45 with a stable vision prescription (unchanged for at least one year), healthy corneas of adequate thickness, and no underlying eye conditions like keratoconus or severe dry eye.
Before & After Care
Preparation
- Stop wearing contact lenses 1-2 weeks before (soft) or 3-4 weeks (hard)
- Attend a comprehensive eye exam and consultation
- Arrange transportation home after the procedure
- Do not wear eye makeup on the day of surgery
- Eat a light meal before your appointment
Aftercare
- Use prescribed antibiotic and lubricating eye drops as directed
- Wear protective eye shields while sleeping for the first week
- Avoid swimming and hot tubs for at least 2 weeks
- Do not rub your eyes for at least 4 weeks
- Attend all follow-up appointments (typically at 1 day, 1 week, 1 month)
Risks & Considerations
All medical procedures carry some degree of risk. Discuss these thoroughly with your surgeon during consultation.
- Temporary dry eyes (most common, usually resolves within 3-6 months)
- Halos or glare around lights at night
- Under- or over-correction (may require enhancement)
- Flap complications (LASIK only)
- Regression — some patients may need a touch-up years later
Recovery Timeline
Most patients notice dramatically improved vision within hours of the procedure. Mild discomfort, light sensitivity, and watery eyes are common in the first 24-48 hours. Avoid rubbing your eyes and use prescribed drops diligently. Full visual stabilization typically occurs within 1-3 months.
Pricing
Prices vary by clinic, technique, and lens type. Contact clinics directly for exact pricing.

Is laser eye surgery painful?
No. Numbing eye drops are applied before the procedure. You may feel slight pressure during LASIK, but there is no pain. Some discomfort is normal during the first 24 hours of recovery.
How long do the results last?
For most patients, the results are permanent. However, age-related changes (like presbyopia after 40) are not prevented by laser surgery. A small percentage of patients may need a touch-up procedure years later.
What is the difference between LASIK and SMILE?
LASIK creates a corneal flap and reshapes the tissue underneath. SMILE uses a small incision to remove a lenticule from inside the cornea — no flap is needed. SMILE has a slightly faster recovery and may cause less dry eye.
Am I a good candidate?
Generally, you need to be at least 18 (ideally 20+), have a stable prescription for at least one year, have healthy corneas of adequate thickness, and not be pregnant or nursing. A comprehensive exam will confirm your suitability.
Can both eyes be done at once?
Yes — in the vast majority of cases, both eyes are treated in the same session. The entire procedure typically takes 15-30 minutes.
