What is Penetrating Keratoplasty?
If the cornea becomes cloudy, the only way to restore sight is to replace or transplant the cornea. Corneal transplant (keratoplasty) is the most successful of all tissue transplants. An estimated 15,000 to 20,000 corneal transplants are done each year in the United States. The success rate depends on the cause of the clouding. For example, corneal transplants for degeneration following cataract surgery and those for keratoconus both have high success rates, while corneal transplants for chemical burns have lower success rates.
What can cause corneal injury?
Corneal injuries include exposure to chemicals, sharp objects, burns, or explosions can cause corneal scarring and severely decreased vision. Most corneal injuries are preventable with protective glasses and proper precautions when dealing with hazardous substances.
