What is a corneal transplant?
A corneal transplant substitutes diseased or scarred corneal tissue with healthy tissue from an organ donor. Healthy corneal tissue that is donated from a local eye bank replaces damaged central corneal tissue. A healthy cornea is important to have because it affects your vision by scattering or distorting light and causing blurred vision and glare. A corneal transplant may be necessary to restore your eye vision. The fourth most common cause of blindness is corneal eye disease and affects more than 10 million people in the world. It is after just cataracts, glacuoma and age-related macular degeneration. Since 1961, more than one million people have had their eye sight restored with this procedure.

Vision After a Cornea Transplant
Your eyesight should slowly improve a few weeks after a corneal graft, but it could take a couple of months up to a year to have full stable vision in the eye that receives the donor tissue. It is possible to undergo LASIK eye surgery to improve your eye vision after your cornea transplant has been fully healed. You will be left with a minor degree of nearsightedness and astigmatism, because the curve of the new corneal tissue cannot match exactly the curve of your natural corneal.
