A cornea transplant replaces diseased or scarred corneal tissue with healthy tissue from an organ donor.
There are two type of cornea transplants: traditional,full thickness cornea transplant( also known as penetrating keratoplasty,or PK) and back layer cornea transplant (aslo known as endothelial keratoplasty,or EK).
There are besically two kinds of corneal transplant -Penetrating Keratoplasty (PK)and Lamellar Keratoplasty (LK).The PK has been followed since ages and connoted as the standard technique to carry out the corneal transplantation.It is commonly performed for the treatment of any full thickness corneal scar or any type of corneal disorder.
The LK is the all-new technique known for partial-thickness corneal transplantation. DALK AND DESK are the commonly performed lamellar keratoplasty procedures. DALK is done to treat any corneal stromal opacities such as in advanced keratoconus. DSAEK is done to treat corneal edema caused by cataract surgery or due to endothelial dyrophies.
