This procedure is designed to replace a damaged or abnormal corneal endothelium (inner cell lining on the cornea) when a patient has decreased visual acuity from guttae (loss of endothelial cells) and stromal swelling. Previously these patients would require a full penetrating corneal transplant, but new technology allows for replacement of only the abnormal endothelium. This results in dramatically shorter visual recovery and lower risk of rejection and wound dehiscence, which can occur with a traditional transplant.

During the procedure a small incision is made and the endothelium and Descemet’s membrane are removed from the inner surface of the cornea. A donor disc of stroma and endothelium is prepared. The disc is then folded gently and inserted into the anterior chamber. An air bubble is placed to push the tissue into place where it eventually heals into a stable position. Typical post-operative results are in the 20/20-20/40 range and patients notice less glare and improved contrast sensitivity.

Indications

• Fuch’s Endothelial Dystrophy
• Pseudophakic Bullous Keratopathy
• Other cause of endothelial failure
• Minimal corneal scarring
• Best acuity 20/40 or worse
