LASIK Eye Surgery
LASIK (Laser-Assisted In Situ Keratomileusis) is the world's most popular vision correction procedure. An ultra-thin corneal flap is created, folded back, and an excimer laser precisely reshapes the underlying corneal tissue to correct the refractive error. The flap is then repositioned. The entire procedure takes about 10–15 minutes per eye and provides clear, spectacle-free vision for the vast majority of patients. At Iswarya Hospital, LASIK is performed with the latest laser platforms for safe and highly accurate results.
🔬 How the Procedure Is Performed
- 1
Anaesthetic drops are instilled to numb both eyes.
- 2
A microkeratome or femtosecond laser creates a thin corneal flap.
- 3
The flap is gently lifted to expose the underlying stroma.
- 4
The excimer laser reshapes the cornea based on the patient's prescription.
- 5
The flap is carefully repositioned and smooths itself into place without sutures.
- 6
A protective shield is placed over the eye; vision improves within hours.
✅ Benefits of LASIK Eye Surgery
- ✓Rapid visual improvement — many patients see 6/6 or better by the next day
- ✓Painless procedure under anaesthetic drops
- ✓Permanent correction for stable prescriptions
- ✓No bandages or sutures required
- ✓Suitable for short-sightedness, long-sightedness, and astigmatism
📋 How to Prepare
- Stop wearing soft contact lenses for 2 weeks and rigid lenses for 4 weeks before evaluation.
- Comprehensive pre-operative examination including corneal topography, thickness, and pupil size.
- Do not apply eye makeup or perfume on the day of surgery.
- Arrange for someone to drive you home after the procedure.
- Eat a light meal before the procedure; avoid alcohol.
⚠️ Possible Risks & Side Effects
- Dry eyes — very common for 3–6 months, managed with lubricating drops
- Glare, halos, and starbursts around lights at night — usually temporary
- Under- or over-correction — may require an enhancement procedure
- Flap complications (rare with experienced surgeons)
- Not suitable for thin corneas, high prescriptions, or keratoconus
Your surgeon will discuss all risks with you before the procedure and take appropriate precautions to minimise them.
💊 Post-Procedure Care
- Rest for the remainder of the day with eyes closed.
- Use antibiotic, steroid, and lubricating drops as prescribed for 1–4 weeks.
- Do not rub the eyes for 4 weeks — this can dislodge the flap.
- Avoid swimming and contact sports for 4 weeks.
- Wear sunglasses outdoors for 1 month.
❓ Frequently Asked Questions
Am I a good candidate for LASIK?
Ideal candidates have a stable prescription for at least 2 years, adequate corneal thickness, no keratoconus, and no severe dry eye disease. A detailed screening determines eligibility.
Is LASIK permanent?
The laser reshaping is permanent. However, age-related changes (presbyopia) may still develop in your 40s, and the prescription could change due to factors unrelated to LASIK.
What if my power is very high?
Very high prescriptions (above -10D or +6D) may not be fully correctable with LASIK. An implantable collamer lens (ICL) may be a better option — this is discussed during your consultation.
