Cornea transplant is also known as corneal transplantation or corneal grafting. It helps to restore vision, reduce pain and improve the appearance of a damaged or diseased cornea.
It is surgical procedure, where a damaged or diseased cornea (clear front layer of eye that covers iris, pupil and anterior chamber) is replaced by donated corneal tissue.
- When the entire cornea is replaced, it is known as penetrating keratoplasty (surgery to the cornea).
- When only a part of the cornea is replaced, it is known as lamellar keratoplasty.
- Third type of transplant is endothelial keratoplasty, which is performed when innermost layer of cornea (endothelium) is damaged. This procedure contains two types of surgeries, DSAEK (Descemet stripping automated endothelial keratoplasty). The donor cornea is thicker in this transplant.
- DMEK (Descemet membrane endothelial keratoplasty). The donor cornea is thinner in this transplant.
