PC Sharma EYE Hospital


Welcome to Cornea Services

Dr. Nishant Sood is a Cornea Specialist at our hospital. The cornea department at our hospital is equipped with :- Anterior segment OCT(As-OCT), Specular microscopy, Anterior segment imaging system, Sirius Topography-Aberrometry. The services provided in cornea department include :

1. Penetrating Keratoplasty : The entire diseased cornea of the host is replaced by a new donor graft & secured with the help of sutures. It can be optical (In cases of cornea scars) or Therapeutic (for non –healing perforated corneal ulcers)

2. Descemets Stripping Endothelial Keratoplasty (DSEK) : The non-functioning endothelial pump of the host cornea is replaced by the healthy donor tissue. The whole cornea is not changed & only the endothelial part is replaced. It can be done in cases of endothelial dystrophies or bullous keratopathy.

3. Deep Anterior Lamellar Keratoplasty (DALK) : The whole cornea, except the descemets membrane & the endothelium are replaced. Chances of rejection in this procedure is minimal as the endothelium is not replaced. It can be done in cases of keratoconus or anterior corneal dystrophies & degenerations.

4. Patch Graft : When only some portion of cornea is affected or perforated, it can be replaced by a small patch of donor corneal tissue.

5. Ocular Surface Disorders : Amniotic membrane grafting can be done in cases of acute chemical injuries, Steven- Johnson syndrome, non –healing epithelial defect etc. Simple Limbal Epithelial Transplantation (SLET) can be done in cases of unilateral or bilateral limbal stem cell deficiency like in cases of chemical injury.

6. Pterygium Surgery : Pterygium (fleshy growth over cornea) is very common in this part of the country. Pterygium surgery is being done with the latest technique of using conjunctival autografting with fibrin glue application.

7. Tissue Adhesive with Bandage Contact Lens (TA-BCL) : This is done for small corneal perforations (<3 mm). The perforation is sealed with the help of cyanoacrylate glue & BCL is applied at the end of procedure.

8. Corneo-Scleral Tear Repair : Open globe injuries involving cornea & sclera should be repaired at the earliest to give best results.
