Inclusion Criteria:

  • candidate for Descemet's stripping with endothelial keratoplasty
  • at least 21 years old
  • willing and able to return for scheduled follow-up visits

Arm Description

An Eye bank pre-cut the donor grafts used for the corneal transplant procedures.

The surgeon dissected the donor grafts used for the transplant procedures.

Outcomes

Primary Outcome Measures

Endothelial Cell Loss
Endothelial cell density was measured by specular or confocal microscopy. Percent cell loss was calculated by subtracting the graft endothelial cell density measured at 6 months from the baseline donor endothelial cell density and dividing by the baseline donor endothelial cell density then multiplying by 100.

Secondary Outcome Measures

Best Corrected Vision
Graft Dislocation

5. Study Description

Brief Summary
Descemet's stripping with endothelial keratoplasty (DSEK) is a cornea-sparing transplant technique that replaces only the diseased endothelial cell layer of the patient's cornea. The DSEK technique requires lamellar dissection of the donor tissue prior to implantation in the patient's eye. The surgeon usually dissects the donor cornea with a microkeratome at the time of surgery. Recently some eye banks have begun to pre-cut the donor graft as an added service. The purpose of this study was to compare outcomes with eye bank pre-cut and surgeon-dissected donor grafts for DSEK.
