SILK Laser Eye Surgery — The Most Advanced Blade-Free, Flap-Free Vision Correction at a Trusted, NABH-Accredited Eye Care Hospital
Freedom from glasses and contact lenses — through SILK, the next generation of laser vision correction. Powered by the ELITA femtosecond platform. Personalised, precise, and performed across 5 eye care centres.
If you have been living with myopia, astigmatism, or the daily inconvenience of glasses and contact lenses, SILK laser eye surgery offers a transformative and permanent solution. SILK — Smooth Incision Lenticule Keratomileusis — is the most advanced form of corneal laser vision correction available today, blade-free, flap-free, and performed entirely within the intact cornea using a femtosecond laser.
What Is SILK Eye Surgery — And Why Is It the Next Generation of Laser Vision Correction?
A blade-free, flap-free procedure that reshapes the cornea from within.
SILK — Smooth Incision Lenticule Keratomileusis — is the most advanced corneal refractive surgery available today. It represents the latest evolution of laser vision correction, offering patients a blade-free, flap-free procedure that corrects myopia and astigmatism by reshaping the cornea from within, without the corneal flap required in LASIK eye surgery.
The procedure uses a femtosecond laser to create a precisely shaped disc of corneal tissue — called a lenticule — within the layers of the cornea. This lenticule is then extracted through a tiny incision of just 2–4mm, permanently changing the corneal curvature and correcting the refractive error. The result is clear, sharp vision, typically from the day after surgery, without the flap-related risks associated with conventional LASIK eye surgery.
According to the American Academy of Ophthalmology, flapless refractive surgery techniques represent a significant advance in corneal biomechanical preservation compared to flap-based procedures — making SILK particularly suitable for patients who were previously borderline candidates for LASIK eye surgery due to corneal thickness or lifestyle considerations.
At MediVision Eye Care Centre, SILK is part of our comprehensive eye care approach to vision correction — offered alongside LASIK eye surgery, PRK, and ICL to ensure every patient receives the most appropriate advanced eye treatment for their individual eyes.
How Is SILK Different From LASIK Eye Surgery — Which Is Right for You?
Both correct refractive errors, but they work differently — and the right choice depends on your eyes.
In LASIK eye surgery, a thin corneal flap (100–120 microns) is first created using either a microkeratome blade or a femtosecond laser, lifted, and then excimer laser reshaping is applied to the exposed stromal bed before the flap is repositioned. The flap never fully reintegrates — it heals by adhesion but remains a structural change in the cornea.
In SILK, there is no flap. The entire procedure is performed within the intact cornea using a single femtosecond laser, creating and extracting a lenticule through a tiny incision without ever lifting the anterior corneal surface — preserving the structural integrity of the anterior cornea far more completely than LASIK eye surgery.
What Are the Advantages of SILK Over LASIK Eye Surgery?
| Feature | SILK | LASIK Eye Surgery |
|---|---|---|
| Flap creation | No flap — entire procedure within intact cornea | Flap created (100–120 microns) |
| Incision size | 2–4mm small incision | Full flap circumference |
| Corneal nerve disruption | Minimal | More extensive |
| Post-operative dry eye | Lower risk | Higher risk |
| Corneal biomechanical strength | Greater preservation | Reduced — flap weakens anterior stroma |
| Suitability for active lifestyle | Excellent — no flap to displace | Caution in contact sports |
| Recovery | 24–48 hours to functional vision | 24–48 hours |
| Laser used | Femtosecond only | Femtosecond + Excimer |
| Prescription range | Myopia up to -12.00D, astigmatism up to -6.00D | Broader range including hyperopia |
Our eye specialist doctors assess every vision correction candidate individually — recommending SILK, LASIK eye surgery, PRK, or ICL based on corneal topography, prescription, tear film, and lifestyle. No single procedure is universally superior.
How Does SILK Eye Surgery Work — A Step-by-Step Guide
A precise, comfortable procedure taking less than 15 minutes, with most patients seeing clearly by the next morning.
SILK is performed at our NABH-accredited eye care hospital as a day procedure — you arrive, undergo surgery, rest briefly, and return home the same day. The entire SILK procedure on both eyes takes less than 15 minutes.
Before the Procedure
Anaesthetic eye drops are instilled to completely numb the surface of the eye, ensuring a painless, comfortable experience throughout. No injections are required. Our eye specialist doctors confirm final measurements and the treatment plan immediately before the procedure begins.
During the Procedure
The ELITA femtosecond laser is precisely positioned over the eye. Two laser passes create the lenticule — a disc of corneal stromal tissue of predetermined size, shape, and thickness, calculated to correct your exact refractive error:
- First pass — creates the posterior surface of the lenticule within the corneal stroma
- Second pass — creates the anterior surface of the lenticule and the small side-cut incision
Our eye specialist doctor then manually separates the lenticule from the surrounding corneal tissue and removes it through the small incision. The cornea is immediately reshaped — the entire laser application takes approximately 25–30 seconds per eye.
After the Procedure
You rest comfortably for a short observation period. Most patients notice dramatically improved vision within hours of surgery and achieve functional vision by the following morning. Antibiotic and anti-inflammatory eye drops support healing, with follow-up appointments at 1 day, 1 week, and 1 month post-operatively. Most patients return to desk work within 24–48 hours; swimming and contact sports should be avoided for 4 weeks.

Are You a Candidate for SILK Eye Surgery — What Does Our Eye Care Hospital Assess?
SILK is not suitable for everyone — a comprehensive pre-operative eye checkup is the only way to determine your eligibility accurately.
Before recommending SILK laser eye surgery, our eye specialist doctors perform a thorough pre-operative assessment to confirm that your eyes are suitable for this form of advanced eye treatment.
Basic Eligibility Criteria for SILK
- Age — at least 18 years old, with maximum benefit typically between 18 and 40
- Stable refractive error — prescription stable for at least 6 months prior to surgery
- Prescription range — myopia up to -12.00D, with or without astigmatism up to -6.00D
- Adequate corneal thickness — measured by pachymetry at your pre-operative checkup
- Healthy cornea — keratoconus or irregular topography are contraindications
- No active ocular surface disease — significant dry eye must be addressed first
- No previous corneal or intraocular surgery — requires specialist assessment
- Not pregnant or breastfeeding — deferred until 3 months after, once prescription is stable
Our eye specialist doctors will recommend the most appropriate alternative — LASIK eye surgery, PRK, or ICL — based on your individual corneal profile. Every patient receives an honest, personalised recommendation, not a one-size-fits-all procedure.

Check My EligibilityWhat Are the Benefits of SILK Laser Vision Correction?
SILK delivers advanced eye treatment outcomes that go beyond simply removing glasses — it transforms daily life.
Freedom From Glasses and Contacts
The most life-changing benefit — waking up with clear vision, driving, swimming, and pursuing sports without optical aids. Most patients achieve 6/6 vision or better.
Blade-Free, Flap-Free Safety
Eliminates flap-related complications associated with LASIK — no flap to displace during contact sport, trauma, or eye rubbing after the procedure.
Reduced Post-Operative Dry Eye
Preserves the anterior corneal surface and disrupts fewer corneal nerves than LASIK, significantly reducing dry eye symptoms.
Greater Biomechanical Stability
The strongest structural layer of the cornea — the anterior stroma — is preserved entirely, in contrast to LASIK, where flap creation weakens this layer.
Rapid Recovery, Minimal Downtime
Most patients achieve functional vision within 24 hours and return to work within 1–2 days, with minimal foreign body sensation.
Precise, Personalised Correction
Every procedure is individually calculated on the ELITA platform, incorporating your exact corneal measurements and topography data.

Why Is Early Vision Correction Through SILK the Right Investment in Your Eye Health?
Every year in glasses or contact lenses is a year of unnecessary limitation.
Eliminates Contact Lens Risks
Contact lens wearers face a lifelong risk of microbial keratitis — a leading cause of preventable corneal scarring. SILK removes this ongoing risk entirely.
Improves Confidence
Freedom from glasses and contacts consistently translates into improved professional confidence, social interaction, and overall quality of life.
Protects Against Dry Eye Progression
Prolonged contact lens wear is a recognised cause of dry eye and corneal surface changes. SILK removes the contact lens from the equation entirely.
Enables Sport, Travel & Life
Swimming, diving, martial arts, and travel are all significantly easier without daily management of glasses or contact lenses.
Comprehensive Eye Care Continues
SILK does not end your relationship with our eye care hospital — regular checkups continue for glaucoma, retina, and cataract monitoring as you age.
