Corneal transplant is one of the most frequently performed human transplant procedures. Since 1961, more than 600,000 corneal transplants have been performed, restoring sight to people ranging in age from nine days to 103 years. Over 90% of all corneal transplant operations successfully restore the corneal recipient's vision. Anyone can be a cornea donor. Cataracts, poor eyesight, or age do not prevent you from being a donor.
