Keratoplasty, more commonly known as corneal surgery treatment is a surgical technique of treating a damaged cornea. Cornea, as we all known, is a clear tissue that covers the front portion of our eyes. Light passes through the cornea to enter our eyes and then goes through the pupil and the lens thus helping in clear vision. If the cornea gets damaged due to scarring from trauma or any other infection or it thins out and loses its shape, then you might be required to undergo a corneal surgery treatment. During the procedure of the treatment, your ophthalmologist removes the damaged portion of the cornea and replaces it with healthy tissues thus restoring your vision. There are different types of corneal surgery procedures:
Full thickness cornea transplant: This refers to replacing all layers of the cornea using donor tissues.
Lamellar corneal transplant: In this form, the surgeon replaces certain selected layers.
Endothelial keratoplasty: In this form of treatment, the surgeon replaces the deepest layers, including the endothelium.
DSAEK endothelial keratoplasty: Your Descemet's membrane and endothelium are removed and replaced with donor endothelium and stroma.
DMEK endothelial keratoplasty: Once again, your Descemet's membrane and endothelium are removed and replaced with donor endothelium but not the stroma.
Depending on the extent of the damage done to your cornea and the portion to be replaced, your ophthalmologist is the best person to decide which form of treatment is best suited for you. The surgery takes about 40-45 minutes of time including the time needed for local anaesthesia, and since it's done on an outpatient basis, so patients can go home once the operation is complete.
