  Purpose
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.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Endothelial Cell Loss [ Time Frame: 6 months after grafting ]
    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 [ Time Frame: 6 months and 1 year after grafting ]
  • Graft Dislocation [ Time Frame: 1 day to 1 month after grafting ]

Enrollment: 40
Study Start Date: January 2006
Study Completion Date: November 2007
Primary Completion Date: October 2007 (Final data collection date for primary outcome measure)
