WHAT IS THE CORNEA?
The cornea is the outermost layer of the eye. Normally, it is a clear, dome-shaped surface that covers the front of the eye. The corneal tissue is arranged in five basic layers, each having an important function. Corneal disorders, such as keratoconus, and other degenerative diseases, if severe enough, will sometime need surgical intervention.
Corneal surgeries cover a wide spectrum. The most common is corneal transplants, usually secondary to eye trauma, or severe scarring from infections. Frequently performed transplant procedures include corneal graft, endothelial keratoplasty, and penetrating keratoplasty. The corneal cross-linking procedure is specifically used to treat keratoconus, although it does not cure the condition.
Recovery from corneal surgery can take anywhere between several months to several years, depending on the type of procedure performed. Eye drops to prevent infection and inflammation will be used indefinitely throughout the recovery process, and sometimes even beyond that to maintain the healing state.
