LASIK Eye Surgery & Advanced Vision Correction — NABH-Accredited Eye Care Hospital, Experienced Eye Specialists
Freedom from glasses and contact lenses — through LASIK eye surgery, SILK, PRK, ICL, and lens-based vision correction. Comprehensive pre-operative eye checkup. Personalised advanced eye treatment for every patient.
Glasses and contact lenses manage refractive errors — but they do not correct them. If you have been living with myopia, hyperopia, astigmatism, or presbyopia, advanced vision correction surgery offers a permanent solution, delivered by experienced eye specialist doctors using state-of-the-art laser technology.
What Are Refractive Errors — And Why Do They Affect Your Vision?
The most common cause of visual impairment worldwide — affecting over 2.6 billion people.
A refractive error occurs when the shape of the eye prevents light from focusing precisely on the retina, the light-sensitive tissue at the back of the eye. Instead of forming a sharp image, light is focused in front of, behind, or across multiple points on the retina, resulting in blurred, distorted, or unfocused vision.
According to the World Health Organization, uncorrected refractive errors are the leading cause of vision impairment worldwide. At our eye care hospital, refractive errors are among the most frequently managed conditions in our comprehensive eye care programme — through both optical correction and advanced vision correction surgery.
What Are the Most Common Types of Refractive Errors?
Myopia (Short-Sightedness)
Distant objects appear blurred while close objects remain clear — the eyeball is slightly longer than average, or the cornea too steeply curved. One of the most rapidly growing conditions worldwide, and the most common indication for LASIK.
Hyperopia (Long-Sightedness)
Close objects appear blurred while distant vision may remain clear. Mild cases are often managed with glasses; moderate to high degrees are corrected through LASIK or lens-based vision correction.
Astigmatism
An irregularly shaped cornea causes light to focus unevenly, producing blurred or distorted vision at all distances. Frequently accompanies myopia or hyperopia, and is effectively corrected through LASIK, SILK, PRK, or toric lenses.
Presbyopia
An age-related condition from the late 30s onwards, as the natural lens gradually loses flexibility. Reading glasses are traditional; refractive lens exchange and multifocal IOLs offer spectacle independence.
What Is Refractive Surgery?
Refractive surgery is a category of advanced eye treatment designed to permanently reduce or eliminate dependence on glasses and contact lenses by correcting the underlying refractive error of the eye — rather than compensating for it externally, refractive surgery changes the focusing properties of the eye itself, either by reshaping the cornea with laser energy or by implanting a corrective lens inside the eye.
Refractive surgery is available for patients with stable refractive prescriptions, typically from the age of 18–21 years onwards. Eligibility is determined by corneal thickness, shape, prescription range, tear film health, and overall ocular health — all assessed during a comprehensive pre-operative eye checkup including corneal topography and Anterior Segment OCT.
Corneal procedures (LASIK, SILK, PRK) reshape the cornea itself. Lens-based procedures (ICL, refractive lens exchange) implant a corrective lens inside the eye. Each is suited to different prescriptions, corneal profiles, and patient goals.
Are You a Candidate for LASIK Eye Surgery or Advanced Vision Correction?
Not every eye is suitable for every procedure — which is exactly why our comprehensive pre-operative eye checkup exists.
Before recommending any vision correction surgery, our eye specialist doctors perform a thorough candidacy assessment. This evaluation protects patient safety and ensures that the recommended procedure delivers the best possible outcome for each individual.
General Criteria for Refractive Surgery Candidacy
- Age — minimum 18–21 years, with a stable prescription for at least 12 months
- Stable prescription — progression of myopia or astigmatism is a contraindication to laser correction
- Adequate corneal thickness — assessed by topography and ASOCT, essential for corneal laser procedures
- Healthy corneal shape — keratoconus or irregular topography are contraindications to LASIK; ICL may still suit
- No active dry eye disease — a relative contraindication to LASIK, treated first where needed
- No systemic conditions affecting healing — autoimmune disease, uncontrolled diabetes, and certain medications are reviewed
The right procedure depends on your prescription, corneal profile, age, lifestyle, and visual goals. No single procedure is universally superior — the best outcome comes from matching the right procedure to the right patient.

Check My EligibilityLASIK & SILK — The World's Most Performed Vision Correction, and Its Most Advanced Evolution
One flap-based, one flap-free — both deliver rapid, predictable freedom from glasses.
LASIK Eye Surgery
The most widely performed refractive surgery globally, with a proven safety record spanning decades and millions of procedures worldwide.
A thin corneal flap (100–120 microns) is created using a femtosecond laser — blade-free and more predictable than a mechanical microkeratome. The flap is lifted, an excimer laser reshapes the corneal stroma with sub-micron precision, and the flap is repositioned, adhering naturally without sutures.
- Myopia — up to approximately -10.00 dioptres
- Hyperopia — up to approximately +4.00 dioptres
- Astigmatism — up to approximately -5.00 dioptres of cylinder
- Rapid recovery — functional vision within 24 hours
- No stitches — the flap heals naturally
- Wavefront-guided customisation available
SILK Surgery
Smooth Incision Lenticule Keratomileusis — the most advanced generation of laser refractive surgery available today, and one of our flagship procedures.
A femtosecond laser alone creates a precisely shaped lenticule within the layers of the intact cornea. The lenticule is extracted through a small 2–4mm incision, permanently altering corneal shape — no flap, no blade, no excimer laser.
- Blade-free and flap-free — eliminates flap-related risks
- Greater corneal biomechanical stability preserved
- Reduced post-operative dry eye
- Suited to active or sports-intensive lifestyles
PRK, ICL & Refractive Lens Exchange — When LASIK or SILK Isn't the Right Fit
Not every eye qualifies for LASIK or SILK — these options extend vision correction to nearly everyone.
PRK — Surface Laser Correction
The original laser vision correction. The corneal epithelium is removed and an excimer laser reshapes the surface directly, without a flap. Recommended for insufficient corneal thickness, irregular topography, or occupational flap concerns. Recovery is 1–2 weeks, with long-term outcomes equivalent to LASIK.
ICL — Lens-Based Correction
A biocompatible collamer lens is placed in front of the natural crystalline lens, which is preserved. Corrects high myopia up to -20.00 dioptres, beyond LASIK's range, without removing corneal tissue. Reversible, with fast recovery and suitability for dry eye patients.
Refractive Lens Exchange (RLE)
The natural lens is removed via phacoemulsification and replaced with a premium multifocal or trifocal IOL — correcting vision and permanently eliminating future cataract risk in one procedure. Recommended for patients over 45 with significant presbyopia or high hyperopia.
Comparing Vision Correction Options — Which Refractive Surgery Is Right for You?
Five procedures. One goal: the clearest, safest path to spectacle freedom for your eyes.
| Procedure | Best For | Corneal Tissue Removed | Flap Required | Natural Lens Preserved | Recovery |
|---|---|---|---|---|---|
| LASIK Eye Surgery | Myopia, hyperopia, astigmatism | Yes | Yes | Yes | 24–48 hours |
| SILK | Myopia, astigmatism — active patients | Yes (lenticule) | No | Yes | 24–48 hours |
| PRK | Thin corneas, previous surgery | Yes | No | Yes | 1–2 weeks |
| ICL | High myopia, thin corneas | No | No | Yes | 24 hours |
| Refractive Lens Exchange | Presbyopia, high hyperopia, over 45 | No | No | No | 1 week |
Your eye specialist doctor will recommend the most appropriate vision correction procedure following your comprehensive pre-operative eye checkup.
