Refractive Surgery

What is Refractive Surgery?

It is a Revolutionary and Innovative technique to correct refractive errors like Myopia, Hypermetropia and Astigmatism.


Laser-assisted in-situ keratomileusis is a procedure to correct refractive errors like short sight, long sight and Astigmatism. By passing the laser beam, the corneal curvature will be modified due to which the power gets corrected.

Treatment for Keratoconus

What is Keratoconus?

Steepening and thinning of the cornea leading to irregular curvature (irregular Astigmatism) is termed as Keratoconus which in turn affects the vision. For progressive Keratoconus, the following modalities of treatment will be done.

C3R – Collagen cross-linking of the cornea by riboflavin – By scraping the superficial layer of the cornea riboflavin drops will be applied and subjected to U-V rays. This procedure aims at strengthening the collagen bondage thereby, inhibits the progression of the Keratoconus.

Corneal Intacs: They are implants in the corneal stroma to reduce Astigmatism and stabilize Keratoconus.

DLK or Deep Lamellar Keratoplasty: Surgical procedure is done in advanced Keratoconus.

3. Deep Lamellar

Rose-K lens: These are Specialized Contact Lens custom-made for Keratoconus treatments.

Implantable Cl (ICL)

ICL (Implantable Contact Lens) this will correct Myopia, Hypermetropia and Astigmatism. This is indicated in people who cannot undergo LASIK treatment because of high power & thinner cornea.

Through the clear corneal small incision, the ICL is implanted in between the natural clear lens and Iris. This is done under topical anaesthesia. Post-operative recovery will be quick.

Proper measurements should be taken before deciding the power of ICL.

ICL implantation requires a surgeon’s expertise. We are proud to inform that Sunayana Eye Hospital is one of the few Eye Hospitals in the country to carry out this procedure successfully.

Keratoplasty or Corneal Grafting:

Keratoplasty or Corneal Grafting will be done for corneal blindness i.e scarring of the cornea due to injury, chemical burn etc. If the retina and optic nerve are in good condition, a corneal replacement will restore the vision.

The donor’s cornea will be grafted on to the patient’s eye. Either the whole cornea will be grafted (penetrating keratoplasty) or partial thickness of cornea (DLK).

The donor cornea is obtained from the deceased’s eye which will be taken within six hours of death.

Anybody can become an eye donor irrespective of their age and sex.

Diabetes, hypertension, cataract surgery are not contraindications for eye donation.

Eyes are the only organs to be taken after death.
