CORNEA
The cornea is vital for vision because it focuses light onto the retina. It’s a clear, dome-shaped front part of the eye that protects it and helps keep vision clear. Damage to the cornea can lead to vision problems, highlighting its importance.

Risks and Complications
While corneal transplants are generally safe, potential risks and complications include
Types of Corneal Transplants
Penetrating Keratoplasty (PKP)
- Overview: Penetrating keratoplasty (PKP) is a full-thickness corneal transplant where the entire cornea is replaced with healthy donor tissue. This is one of the oldest and most common forms of corneal transplant, used to treat conditions such as corneal scarring, dystrophies, and keratoconus.
- Procedure: The surgeon removes a circular portion of the patient’s damaged cornea and replaces it with a matching circular donor cornea, sewing it in place with sutures. PKP is typically performed under local anesthesia with sedation or general anesthesia.
- Recovery: Recovery can take several months, as the sutures need time to heal and vision may fluctuate during this period. Regular follow-up appointments are necessary to monitor healing and progress.
Deep Anterior Lamellar Keratoplasty (DALK)
- Overview:DALK removes the outer layers of the cornea up to Descemet’s membrane, leaving the endothelium intact. This procedure may require specialized equipment and techniques.
- Procedure:In ALK, the surgeon carefully removes the anterior layers of the cornea and replaces them with donor tissue. The endothelium is left intact, reducing the risk of rejection.
- Recovery:Recovery from ALK is generally quicker than PKP, as the endothelium is preserved.
Descemet's Stripping Endothelial Keratoplasty (DSEK)
- Overview: DSEK is similar to DSAEK but uses a thinner donor graft composed of the endothelium, Descemet’s membrane, and a very thin layer of stroma.
- Procedure: The procedure is similar to DSAEK, but with a thinner graft that allows for better fit and quicker recovery.
- Recovery: Recovery is generally faster, and patients may experience improved vision within a few weeks.
Descemet's Membrane Endothelial Keratoplasty (DMEK)
- Overview: DMEK is the most advanced form of endothelial keratoplasty, involving the replacement of only the endothelium and Descemet’s membrane with an ultra-thin donor graft.
- Procedure: The surgeon removes the patient’s damaged endothelium and Descemet’s membrane and replaces it with the donor graft. Precision and skill are required to handle the delicate tissue.
- Recovery: Recovery is rapid, and vision can improve significantly within a short period. The risk of rejection is lower than in other transplants.
These different types of corneal transplants offer various options to address specific corneal issues. The choice of procedure depends on the patient’s condition, the surgeon’s expertise, and the expected outcomes.

FAQ'S
What is a corneal transplant?
A corneal transplant, also known as keratoplasty, is a surgical procedure to replace part of your cornea with corneal tissue from a donor. The cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power.
What are the types of corneal transplant surgeries?
Penetrating Keratoplasty (PKP): A full-thickness transplant where the entire cornea is replaced.
Deep Anterior Lamellar Keratoplasty (DALK): Replaces the front layers of the cornea, leaving the inner endothelial layer intact.
Endothelial Keratoplasty (EK): Replaces only the innermost layer of the cornea.This includes Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK).
What is Penetrating Keratoplasty (PKP)?
Penetrating Keratoplasty (PKP) is a full-thickness corneal transplant where the entire cornea is replaced. It is commonly used for conditions where the whole cornea is diseased, such as in advanced keratoconus, corneal scarring, or severe corneal thinning.
Deep Anterior Lamellar Keratoplasty (DALK): Replaces the front layers of the cornea, leaving the inner endothelial layer intact.
Endothelial Keratoplasty (EK): Replaces only the innermost layer of the cornea.This includes Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK).
What is Deep Anterior Lamellar Keratoplasty (DALK)?
Deep Anterior Lamellar Keratoplasty (DALK) is a partial-thickness corneal transplant that replaces the front layers of the cornea while keeping the healthy endothelial layer. This technique is often used for conditions affecting the corneal stroma but sparing the endothelium, such as keratoconus or corneal dystrophies.
Deep Anterior Lamellar Keratoplasty (DALK): Replaces the front layers of the cornea, leaving the inner endothelial layer intact.
Endothelial Keratoplasty (EK): Replaces only the innermost layer of the cornea.This includes Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK).
What is Endothelial Keratoplasty (DSEK/DMEK)?
Endothelial Keratoplasty (EK) includes procedures like Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK). These surgeries replace only the damaged endothelial layer of the cornea, which is responsible for pumping fluid out of the cornea to keep it clear. They are commonly used for endothelial dysfunction conditions, such as Fuchs' dystrophy.
Deep Anterior Lamellar Keratoplasty (DALK): Replaces the front layers of the cornea, leaving the inner endothelial layer intact.
Endothelial Keratoplasty (EK): Replaces only the innermost layer of the cornea.This includes Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK).
How is the donor cornea prepared?
The donor cornea is typically prepared by an eye bank. For PKP, the entire cornea is used. For DALK and EK, the corneal tissue is carefully dissected to isolate the necessary layers. The preparation can be done manually or with the assistance of a femtosecond laser.
Deep Anterior Lamellar Keratoplasty (DALK): Replaces the front layers of the cornea, leaving the inner endothelial layer intact.
Endothelial Keratoplasty (EK): Replaces only the innermost layer of the cornea.This includes Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet Membrane Endothelial Keratoplasty (DMEK).
