Cornea Transplantation

A cornea transplant, also called a keratoplasty, is a surgical procedure that replaces part of a diseased or injured cornea with healthy tissue from a carefully screened organ donor.

The traditional cornea transplant is called a penetrating or full-thickness transplantation and is still the most commonly performed procedure. It has a very high success rate for patients with diseases such as keratoconus or corneal scars from trauma or infection. The full-thickness transplant involves replacing a central portion of the cornea and stabilizing it with multiple sutures. These sutures may be selectively removed over the course of a year to improve vision by decreasing astigmatism, irregularities in the shape of the cornea.

Advances in surgical technique have led to the development of selective cornea transplants in which only the diseased portion of the cornea is removed. In these surgeries, either the front layers of the cornea are replaced, as in Deep Anterior Lamellar Keratoplasty (DALK), or the back layers of the cornea are replaced, as in Descemets Stripping Endothelial Keratoplasty (DSEK). Eyes with full-thickness abnormalities may not qualify for these newer techniques, but patients with Fuchs dystrophy and bullous keratopathy are usually excellent candidates for DSEK. The advantages of these techniques are that they result in faster visual recovery, improved structural integrity and, in some cases, a decreased risk of graft rejection.

Expert Doctors

Keratoplasty or cornea transplantation is a surgery which substitutes or replaces a defective portion of the corneal tissue from a person with healthy corneal tissue from an organ donor. This is one of the common procedures for any eye care hospital in Hyderabad. Krishna Medical Institute of Sciences(KIMS) has advanced technologies, a special team and well-trained staff which are some of the necessary factors to be considered the best eye transplant in Hyderabad.


Is KIMS Top Cornea Transplantation Hospital in Hyderabad

Techniques taken up by the hospital are necessary to rank it as the top hospital for corneal transplant surgery in Hyderabad. We at KIMS provide three procedures for a cornea transplant:


1. Penetrating Corneal Transplantation

Penetrating Keratoplasty or penetrating corneal transplant is a whole cornea transplant. It will be very common and a conditional practice in the top cornea transplantation hospital in Hyderabad. The surgeon removes a little disc of corneal tissue through incisions. A specialized kind of instrument is used to make a precise circular cut.

The donor cornea is fitted into the incision after being sliced. The new cornea is then stitched into place by the surgeon using sutures. Later, the stitches will be removed when visiting the doctor in the future.


2. Lamellar Endothelial Keratoplasty

The cornea consists of six layers made up of different cells allotted specific functions. Thanks to the advancement of technologies, the entire cornea can now be replaced selectively rather than all at once because of improvements in transplantation technology. This is called a lamellar transplant. Moreover, any top hospital for corneal transplant surgery in Hyderabad practices this surgery with due precaution.

This procedure lessens the likelihood of the rejection of the graft as well as the requirement for post-operative drugs and speeds up visual recovery. All kinds of lamellar corneal transplants have been completed by our cornea specialists.


Selective replacement of the same is possible if the endothelium is defective and is classed as:

i. DSEK: After putting the donor cornea in a synthetic anterior chamber, the donated tissue is surgically separated from the body during DSEK using specialized dissectors. This divides the cornea's rest from Descemet's membrane, some stroma, and Dua's layer.

ii. DSAEK: In DSAEK, a motorized microkeratome blade that can cut at a precise depth of around 350 microns is used to do the same technique.

iii. DMEK: The entire treatment is different from DMEK because the professional corneal expert just removes the donor Descemet's membrane using a specific no-touch method and leaves behind no stroma.


3. Lamellar Keratoplasty DALK

This procedure is beneficial as it is a lesser invasive operation than the whole manual cornea thickness implant. The major requirements for this process include advanced surgical skills, and knowledgeable surgeons possessing great skills. Hence, the top hospital for corneal transplant surgery in Hyderabad will carry expertise, especially in DALK.

Scars affecting the first three layers of the cornea, stroma-only diseases like keratoconus, other corneal ectasias like Keratoglobus, Pellucid marginal degeneration, or Terrien's marginal degeneration, as well as post-LASIK ectasias, are treated using DALK
