✨ LASIK & Refractive Surgery

LASIK Surgery —
Life Without Glasses

LASIK is one of the most life-changing procedures in ophthalmology. Dr. Swati Agarwal performs thorough candidacy evaluations and, where suitable, recommends the refractive procedure that best matches your eyes — not just the most popular one.

How It Works

What LASIK actually does

LASIK reshapes the cornea — the transparent front surface of the eye — using a precise excimer laser. By altering the cornea's curvature, we change how light focuses on the retina, permanently correcting the refractive error that causes blurred vision.

A thin corneal flap is created (via microkeratome blade or, in Femto LASIK, a femtosecond laser), lifted to expose the underlying tissue, the laser reshapes the cornea in under a minute, and the flap is repositioned. No stitches required — the flap adheres naturally.

Procedure Options

Which procedure is right for you?

Femto LASIK (Blade-Free)

Both the flap creation and corneal reshaping use laser technology. The most precise form of LASIK available — ideal for patients with higher prescriptions or those wanting the most advanced technique.

🔆
Standard LASIK

Flap created with a microkeratome, corneal reshaping with excimer laser. Well-established, highly effective, and suitable for most candidates. Excellent outcomes with a long track record.

🌊
PRK / LASEK

Surface laser ablation — no flap is created. Preferred for thin corneas, contact sport participants, or professions with high risk of eye trauma. Slightly longer recovery than LASIK but equivalent final outcomes.

ℹ️ If Not Suitable for LASIK

High prescriptions or thin corneas may be better treated with an ICL (Implantable Collamer Lens) — a lens placed inside the eye, in front of the natural lens, without removing corneal tissue. Dr. Swati evaluates all options at the candidacy appointment.

Am I a Candidate?

The 6 candidacy criteria

1

Age 18+ (ideally 21+) with stable prescription

Prescription must be unchanged for at least 12 months. We prefer 21+ as myopia often continues changing through the late teens.

2

Prescription within treatable range

Myopia up to -10.00D, hyperopia up to +4.00D, astigmatism up to 5.00D. Higher prescriptions may require ICL instead.

3

Adequate corneal thickness

Measured precisely by pachymetry. Sufficient tissue must remain after laser treatment to maintain structural integrity.

4

Normal corneal topography — no keratoconus

Keratoconus (corneal thinning/bulging) is an absolute contraindication. We screen carefully for even subtle early-stage disease.

5

No significant dry eye

LASIK temporarily reduces corneal nerve sensitivity and can worsen dry eye. Significant pre-existing dry eye requires treatment first or a switch to PRK.

6

No disqualifying medical conditions

Uncontrolled autoimmune disease, pregnancy, and active eye infection are contraindications. Each patient's full history is reviewed.

📋 Before Your Evaluation

Remove soft contact lenses 7 days before your evaluation. Remove hard/rigid lenses 3–4 weeks before. Bring your current glasses. You cannot drive yourself home — the pupils are dilated during the assessment.

What to Expect

From evaluation to clear vision

1

Candidacy evaluation (60–90 min)

Corneal topography, pachymetry, tear film assessment, cycloplegic refraction, dilated fundus exam, and pupil measurement. Full discussion of results and options.

2

Surgery day

Numbing drops applied. LASIK itself takes under 15 minutes for both eyes. Most patients notice dramatically improved vision within hours of the procedure.

3

Day-1 review

Post-operative assessment. Many patients can drive to this appointment themselves — a remarkable turnaround from the day before.

4

Stabilisation (1–3 months)

Vision gradually stabilises and sharpens as the cornea heals. Protective eyewear recommended during sports for 2–4 weeks. Avoid water in eyes for 2 weeks.

Common Questions

Frequently Asked Questions

How long does LASIK last?
LASIK permanently reshapes the cornea — the correction does not wear off. However, presbyopia (age-related near vision loss) will still develop naturally after age 40–45 regardless of LASIK.
Is LASIK painful?
No. Numbing drops are applied before the procedure. You may feel pressure during flap creation but no pain. Some patients experience mild discomfort or scratchiness for a few hours after surgery, which resolves quickly.
What if I move my eyes during surgery?
All modern LASIK lasers have eye-tracking systems that follow eye movements in real time and adjust the laser position accordingly. Involuntary small movements are compensated automatically.
Can LASIK correct astigmatism?
Yes — LASIK and Femto LASIK both correct astigmatism up to approximately 5.00D. Astigmatism correction is included in the same procedure as myopia or hyperopia correction.
What are the risks?
LASIK is extremely safe — complication rates in well-selected candidates are very low. Risks include dry eye (usually temporary), halos/glare (usually improve with time), undercorrection/overcorrection (treatable with enhancement). Serious complications are rare when proper candidacy criteria are followed.
I'm over 40 — can I still have LASIK?
Yes, but we discuss presbyopia honestly. LASIK corrects distance or near vision, not both. Monovision LASIK (one eye for distance, one for near) is an option for some patients over 40 wishing to reduce total spectacle dependence.
