A corneal transplant, also known as corneal grafting or keratoplasty, is a surgical procedure aimed at restoring vision and improving the quality of life for individuals suffering from corneal diseases or injuries. The cornea is the transparent, dome-shaped layer covering the front of the eye, responsible for refracting light and focusing it onto the retina. However, when the cornea becomes damaged or diseased, it can lead to vision loss or severe discomfort. A corneal transplant involves replacing the damaged cornea with a healthy donor cornea, generously provided by an eye bank. This procedure has proven to be highly successful in treating various corneal conditions and enabling patients to regain clear vision.
1. Penetrating Keratoplasty (PK): This is the most common and oldest type of corneal transplant surgery. It involves replacing the entire thickness of the cornea with donor tissue.
2. Endothelial Keratoplasty (EK): This type of corneal transplant surgery replaces only the inner layer (endothelium) of the cornea. It is typically used to treat conditions such as Fuchs’ dystrophy.
3. Anterior Lamellar Keratoplasty (ALK): This type of corneal transplant surgery replaces only the front, outer layer (anterior lamella) of the cornea. It can be used to treat conditions such as keratoconus.
4. DALK (Deep Anterior Lamellar Keratoplasty): This type of corneal transplant surgery replaces the front, outer layers of the cornea but leaves a portion of the inner layers intact. It can be used to treat conditions such as keratoconus.
5. DSAEK (Descemet’s Stripping Automated Endothelial Keratoplasty): This type of corneal transplant surgery is similar to EK but uses automated technology to replace the cornea’s inner layer. It can be used to treat conditions such as Fuchs’ dystrophy.
6. DMEK (Descemet’s Membrane Endothelial Keratoplasty): This type of corneal transplant surgery is similar to DSAEK but replaces only the inner layer of the cornea. It can be used to treat conditions such as Fuchs’ dystrophy.
7. Keratoprosthesis: This type of corneal transplant surgery involves replacing the entire cornea with a synthetic device. It is typically used when other types of corneal transplant surgery are not possible.
Individuals suffering from corneal diseases or injuries may experience symptoms such as:
Blurred or Distorted Vision: A noticeable decline in visual acuity, making it challenging to perform daily tasks.
Corneal Scarring: Visible clouding or scarring of the cornea, affecting its transparency.
