Refractive procedures are performed to reduce or remove the need for spectacles or contact lenses.

It is best done after the refractive error stabilizes, ie., at least for two years, after the age of 18 years.

Various procedures include, LASIK, SMILE, Advanced Surface Ablation, Intraocular Collamer Lens and Refractive Lens Exchange.

The choice of the procedure depends on, the amount of the refractive error, the corneal thickness and curvature and age of the patient.


Is a procedure, where a flap of the cornea is made and raised. The laser beam is aligned on the cornea and the treatment applied, as per the precalculated data. The flap is replaced and eye drops instilled. The other eye is treated in a similar manner and the patient is made to wear a pair of dark glasses. Eye drops will be prescribed. A final check up will be done before you leave the centre. Your appointment will be scheduled for the next day, with your doctor.

Femto lasik, is the laser applied to make a flap. Microkeratotome assisted – flap is made with an automated microkeratome.

Customised LASIK, includes treating aberrations, other than those corrected by spectacles or lenses.

The error that can be corrected is between -1.00 to -8.00 sph and +1.00 till +6.0 D sph.
Astigmatism upto 4 D can be corrected.

LASIK is a painless procedure. You may feel some discomfort for 4 to 6 hours after the procedure. You will be given some oral medication for the discomfort and you would best sleep out the discomfort. 95% of the vision is restores in 24 hours and the rest by 1 week. One can resume most activities in 24 to 48 hours.


Small Incision Lenticule Extraction: is a new technology, which alters the shape of the cornea, by removing a disc of corneal tissue through a small incision. The advantage is that there is a small tunnel and no flap. Chances of dryness or injury to the flap are averted and the strength is maintained. However some restrictions remain pertaining to non correction of astigmatism over 2 D. Enhancement or retouch up if needed at a late date may be difficult.


This technique is offered to patients as an alternative to LASIK, for lower errors ie., less than 4 or where the error is more than -8.0 or if the corneal thickness is on the borderline for LASIK

It is predictable, but there is a small chance of some error relapsing.

Vision takes time to stabilize ie., upto 8 to 12 weeks.

Slightly more painful, than LASIK.

But offers a hope to patients with high errors where SMILE and LASIK cannot be offered.


For patients whose cornea is too thin to undergo Lasik, a soft foldable lens can be inserted to correct the refractive error to as close to zero as possible. This is suitable for patients between the age of 18 to 35 years. It is a safe procedure.


For near vision correction after the age of 40 years supracor treatement is offered. This will reduce the dependence of glasses.
