Corneal Transplants are performed when the cornea becomes cloudy from scarring, infection, or disease. Traditionally, the full-thickness of cornea is replaced. Newer approaches remove only the affected portion of cornea-either the front part or back layer. Donor corneal tissue is used for this sight-saving procedure. Visual recovery varies from one month to six months.
Lasik is also considered corneal surgery as this involves re-shaping of the cornea with laser to improve one's uncorrected visual acuity. In this procedure, an initial laser creates a corneal flap which is then lifted so that a second laser can re-shape the central cornea. This works for near-sightedness, far-sightedness, and astigmatism. Lasik has been performed for nearly twenty years now and has revolutionized vision correction.
