Cornea Transplant

Penetrating Keratoplasty (PKP):

Some patients require a full thickness cornea transplant to improve vision in the setting of scarring, infection, trauma, or corneal thinning disorders, such as keratoconus. This surgery involves replacing the entire thickness of the cornea with donor corneal tissue. The transplant is held in place by stitches that are later removed as the eye heals.

Descemet’s Stripping Endothelial Keratoplasty (DSEK)

Certain disorders of the cornea affect the inner layer of cells called the endothelial cells. This results in swelling of the cornea and blurred vision. DSEK surgery replaces this unhealthy layer of cells with donor corneal tissue to improve vision. It has the benefit of faster visual recovery than a full thickness corneal transplant and less astigmatism.

Ocular Surface Procedures

Amniotic Membrane Grafting

Patients with disorders of the surface of the eye may benefit from placement of amniotic membrane tissue to help the eye heal. This procedure is either performed in the operating room or in the clinic and may require the use of stitches or a contact lens to hold the material in place. Amniotic membrane tissue provides support and nutrition to the ocular surface to aid healing in eyes with chemical injury, ulceration, severe dry eye, and after certain types of infection.

Pterygium Excision

A pterygium is a wing shaped growth of fibrovascular tissue that extends onto the cornea. It may cause ocular irritation and redness or interfere with the vision. It is removed surgically in the operating room, usually along with the application of medication or placement of additional tissue to prevent recurrence.
