Study Details

Study Description

Brief Summary

This project compares the Neusidl Corneal Injector (NCI) device developed by Fischer Surgical, Inc. for the delivery of tissue into the eye in DSAEK surgery to the current standard forceps insertion DSAEK technique. The goal of this study is to examine the damage to the corneal endothelium resulting from the use of the NCI device in comparison to the use of our standard surgical DSAEK technique over time.

Condition or Disease Intervention/Treatment Phase
  • Device: NCI Insertion
  • Procedure: Standard Forceps Insertion

Arms and Interventions

Arm Intervention/Treatment
Experimental: NCI Insertion

Device: NCI Insertion
DSAEK surgery will be performed using the NCI to insert the donor tissue.

Active Comparator: Standard Forceps Insertion

Procedure: Standard Forceps Insertion
DSAEK surgery will be performed using forceps to insert the donor tissue. This is our long-established technique for DSAEK, with well-documented excellent results.

Outcome Measures

Primary Outcome Measures

  1. Decrease in Endothelial Cell Density From Baseline Over Time [6, 12, 24, and 60 Months]

    Endothelial cell density (ECD) will be captured at each follow-up visit using a non-contact specular microscope. % Cell reduction from pre-operative baseline ECD will be calculated for each patient, and compared between treatment arms to evaluate each instrument's effect on long-term post-operative endothelial cell density.

Secondary Outcome Measures

  1. Adverse events [Any time during follow-up period (5 years)]

    Each patient will be monitored for incidence of graft dislocation, primary graft failure, immunologic graft rejection, and late endothelial failure. Rates will be compared between groups to ensure that the NCI does not increase the risk of these adverse events.
