A corneal transplant performed on a patient is often the result of an eye disease or eye injury, and is meant to restore vision. After a corneal transplant, patients often require specialty contact lenses to achieve clear and comfortable vision.

Types of corneal transplants:

  • Penetrating Keratoplasty (PK): A corneal transplant of the full thickness of the cornea.
  • Anterior Lamellar Keratoplasty (ALK): A corneal transplant where only the front part of the cornea is replaced.
  • Deep Anterior Lamellar Keratoplasty (DALK): A corneal transplant where about 95% of the original cornea is replaced (often used to treat patients with keratoconus).
  • Endothelial Keratoplasty (EK): A corneal transplant where only the back layer of the cornea is corrected.

Often, when a patient successfully undergoes a corneal transplant, the eye is not cured of the disease entirely. Post corneal transplant patients will notice dramatic improvements in their eyes, yet their vision will still need specialty contact lenses for correction.

Scleral lenses are often the optimal choice as the lens is designed to vault over the cornea entirely- meaning the lens will not touch your transplant at all. Even after a cornea transplant, the cornea may still be considered irregular and diseased. Scleral lenses allow one’s cornea to remain hydrated, provide clear vision, and avoid any risk of corneal scarring. Other options are possible, yet scleral lenses make for a safe alternative that won’t negatively affect the cornea.
