Advanced Refractive Surgery Options at Susrut Eye Foundation & Research Centre
At our Refractive Surgery Centre, we specialize in all modern vision correction procedures. Depending on your eye health, spectacle power, corneal thickness, and lifestyle, our experts will recommend the best procedure for you.
1. LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK is the most widely performed laser vision correction surgery worldwide. It reshapes the cornea (the clear front part of the eye) so that light focuses correctly on the retina, giving clear vision without glasses.
How LASIK Works
- A thin flap is created on the cornea using a femtosecond laser
- The underlying corneal tissue is reshaped with an excimer laser
- The flap is then repositioned — no stitches required
Advantages of LASIK
- Quick procedure – usually 10–15 minutes for both eyes
- Painless with only numbing drops required
- Fast recovery – most patients achieve 20/20 vision within 1–2 days
- Long-lasting results for stable spectacle power
- Can treat myopia, hyperopia, and astigmatism
Who is Eligible
- Age 18+ with stable spectacle power for at least 1 year
- Adequate corneal thickness
- No active eye disease like glaucoma, keratoconus, or severe dry eyes
LASIK is ideal for patients with moderate spectacle power and healthy corneas.
2. Phakic IOL (Implantable Collamer Lens / ICL)
Phakic IOL is a revolutionary option for patients who cannot undergo LASIK due to thin corneas, high spectacle power, or dry eyes. It involves implanting a special lens inside the eye (like a permanent contact lens), without removing the natural lens.
How Phakic IOL Works
- A customized, ultra-thin lens is inserted behind the iris and in front of the natural lens
- It bends light rays correctly, allowing clear vision without glasses
- The procedure is reversible — the lens can be removed or replaced if required
Advantages of Phakic IOL
- Suitable for very high myopia (even -10 to -20 D)
- Preserves natural corneal shape and thickness
- Excellent quality of vision, often sharper than glasses or contact lenses
- Quick recovery with minimal discomfort
- Long-term solution, yet reversible if needed
Who is Eligible
- Patients with high myopia or thin corneas not suitable for LASIK or SILK
- Age 18–45 years with stable prescription
- Healthy eyes without cataract or severe retinal disease
Phakic IOL is ideal for patients who want spectacle-free vision but are not candidates for laser procedures.
3. SILK (Smooth Incision Lenticule Keratomileusis)
SILK is the latest generation flapless, minimally invasive refractive surgery — an advanced alternative to LASIK. It uses a femtosecond laser to create a small lenticule (a disc-shaped piece of corneal tissue), which is removed through a tiny incision.
Unlike LASIK, no flap is created, making it gentler on the cornea.
How SILK Works
- A femtosecond laser creates a precise lenticule inside the cornea
- The lenticule is removed through a small (2–3 mm) incision
- The cornea is reshaped, correcting the refractive error
Advantages of SILK
- Flapless and minimally invasive – faster healing, less risk of flap-related complications
- Reduces risk of dry eyes compared to LASIK
- Better corneal biomechanical stability (cornea stays stronger)
- Clear vision typically within 24–48 hours
- Long-lasting results with a high safety profile
Who is Eligible
- Patients with myopia and astigmatism
- Those seeking a safer, newer alternative to LASIK
- Individuals concerned about flap-related issues or dry eye risk
SILK is perfect for patients who want the most advanced, minimally invasive vision correction available today.

CAMP
Diabetic Retinopathys Screening Camp
Diabetic Retinopathy screening camps are often held in community vision centers because screening people for this disease requires special medical expertise. DR screening camps are specialized exclusively in the diagnosis and treatment of this disease. However, while the focus is on detecting diabetic retinopathy before it causes irreversible blindness (and this sometimes means detecting diabetes in patients who don’t know they have it), patients who suffer from other eye disorders will also be referred to our main hospital.
What Are The Various Types Of LASIK Treatments Available In Susrut?
The excimer reshaping can be patterned in three ways
- Wavefront Optimised (PROSCAN in Teneo 317)- Here the refractive error (as measured conventionally in the clinic) is entered in the excimer laser. Only spherical and cylindrical refractive errors can be corrected. Additional correction is made by the machine itself to reduce creation of spherical aberration (a type of higher order aberration).
- Wavefront Guided (ZYOPTIX HD in Teneo 317)- Here wavefront data from ZDW3 is automatically transferred to the excimer laser. This pattern provides an opportunity to correct higher order aberrations (in addition to correcting spherical and cylindrical errors). It has been shown to provide better vision to patients with pre-existing higher order aberrations.
- Near vision correction (SUPRACOR in Teneo 317) – For patients older than 45 years, who have both distance and near vision errors, this method provides intermediate/near vision (eg: mobile phone use) correction, in one or both eyes, in addition to distance vision correction in both eyes.
What Is PRK?
PRK is an alternative refractive procedure. Here flap making is not required. The excimer laser reshapes the cornea, after the epithelium (outer lining) of the cornea is removed. Following PRK, the discomfort level is more and visual recovery takes longer, compared to LASIK. It is meant for patients with thinner corneas and certain corneal disorders (like EBMD).
What Is Phakic IOL / ICL / IPCL?
For patients with very high refractive error (spectacle power), which is not amenable to LASIK, the refractive error can be corrected by placing an intraocular lens (different from the intraocular lens implanted during cataract surgery) inside the eye.
What is Laser Correction?
Excimer Laser
- LASIK/PRK – for correcting refractive error, so that patients do not need to wear spectacles any more
- PTK – for treatment and removal of small irregularities on the surface of the cornea
Femtosecond Laser
- FLACS – enhances precision and accuracy during cataract surgery
- Bladeless LASIK – avoids using blades (microkeratomes) during LASIK
Frequency Doubled NdYAG Laser
- Used for treating various retinal diseases like diabetic retinopathy, retinal strokes, retinopathy of prematurity (ROP), retinal breaks, etc
PDT Laser
- Used for the treatment of choroidal neovasular membranes (CNVM) in age related macular degeneration
YAG Laser
- Capsulotomy – For clearing the opaque layer, behind the IOL, which forms in some patients after cataract surgery
- Peripheral irodotomy – Prevent further deterioration in some forms (angle closure) of glaucoma.
Cataract FAQs
Can both eyes be treated in one procedure?
Your doctor will typically arrange the second procedure a few weeks following the first if you have cataracts in both eyes. Nonetheless, treating both eyes in a single treatment on the same day is becoming more and more typical.
How long do the effects of cataract surgery last?
Surgery for a cataract is permanent. The IOL can remain in the eye for the entirety of a person’s life without needing to be taken out or changed.
Will I need to have cataract surgery again?
Natural lenses are removed during cataract surgery and replaced with artificial ones that should last a lifetime and are not prone to degradation.
Are cataracts painful?
Although they don’t hurt, cataracts can be frustrating and uncomfortable since they make it harder to see well. They take decades to manifest symptoms, which appear gradually over time.
Is the surgery safe?
Currently, one of the safest surgical techniques is cataract surgery.
Can cataracts grow back?
No, your eye’s clouded lens is removed during cataract surgery and replaced with an artificial lens. After the natural lens is removed and replaced with an artificial one, cataracts cannot regrow.
