Brief Summary:
The purpose of this study is to determine whether the surgical outcomes in patients undergoing Descemet's Stripping Endothelial Keratoplasty (DSEK) are improved with the use of an insertion device over the traditional forceps insertion method.

Condition or disease Intervention/treatment Phase
Corneal Transplantation Device: EndoSaver™ Corneal Endothelium Delivery Instrument Phase 2

Detailed Description:

Laboratory studies and clinical functionality tests have shown that the study device safely forms the tissue without creasing or folding. It allows the allograft tissue to safely pass into the anterior chamber without compression, crushing, or squeezing the endothelial cells.

The device provides continuous irrigation into the eye to prevent collapse of the anterior chamber during insertion. Our study will focus on the safety and efficacy of the novel instrument over the current method of insertion (forceps).

FDA has classified the device as Class I, Reserved.
