The cornea is the portion of our eyes that filters light into our eyes and help in clear vision. It often happens that due to some kind of scarring or disease, your cornea no longer lets the light enter your eyes properly. It is at that point of time that your ophthalmologist will suggest corneal surgery treatment for you. Also known as keratoplasty, corneal surgery is a surgical form of treatment that is performed to remove all or part of the damaged cornea and replace it with healthy donor tissue. There are three types of corneal transplant treatments available, and the type of treatment that one has to undergo depends on how much of the cornea has been damaged and requires replacement. Penetrating keratoplasty is a full-thickness transplant, deep anterior lamellar keratoplasty involves replacing just the outer and middle (front) layers of the cornea and finally, endothelial keratoplasty refers to replacing the rear layers of the cornea. Apart from these three widely practised forms of corneal surgery treatment, DASEK and DMEK form of surgeries are also available. While DSAEK involves removing your Descemet's membrane and endothelium and replacing it with the donor's endothelium and stroma, DMEK is removing your Descemet's membrane and endothelium and replacing it with the donor's endothelium but not the stroma. Speaking about the surgery duration, the entire procedure gets completed within a couple of hours' time, and since the surgeries are performed on an outpatient basis, so you can go home after the same is done.
