Corneal Surgery 

Corneal surgery is one of the most common forms of eye surgery performed by an ophthalmologist and includes almost all of the surgery types found on the refractive surgery page. There are also numerous other non-refractive surgery procedures which fall under the corneal surgery umbrella, and these are:

 

Corneal Transplant Surgery

 

Corneal transplant surgery, which is also sometimes referred to as corneal grafting, is a surgical procedure used to replace a damaged or diseased cornea with donated corneal tissue. There are two types of corneal transplant surgery; namely penetrating keratoplasty where the entire cornea is replaced and lamellar keratoplasty where the cornea is only partially replaced. The donated cornea is from a recently deceased donor with no history of eye disease.

 

Keratoprosthesis

Keratoprosthesis is a surgical procedure which is used to replace a diseased cornea with an artificial one. This eye surgery is generally only performed after a patient has undergone corneal transplant operation and the donor corneal transplant either failed or was rejected.

 

Phototherapeutic Keratectomy

Also known as PTK, phototherapeutic keratectomy uses a laser to treat various ocular disorders by removing tissue from the cornea during a laser-assisted surgical procedure. PTK is an effective way of removing superficial corneal opacities and surface irregularities. This corneal surgery procedure is similar to the refractive surgery procedure known as photorefractive keratectomy.
