Corneal transplantation involves certain risks, but with the current advances in medical technology, the risks are relatively low, but any surgery carries certain risks. The three main types of corneal transplantation include lamellar corneal transplantation, penetrating corneal transplantation, and corneal endothelial transplantation. Postoperative risks such as secondary glaucoma, infection, poor corneal healing, and clouding of the corneal implant may occur, but most of them are manageable. And although corneal transplantation carries some surgical risks, postoperative rejection is low because the cornea does not contain blood vessels. Postoperative risks can be minimized by following the doctor’s instructions for postoperative medication, keeping the eye clean, and using the eye safely. Post-operative corneal transplant patients are advised to follow the doctor’s instructions, have regular check-ups, and seek prompt medical attention when discomfort occurs.
