This study compares the outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) performed using an intraocular lens injector (injector) versus the Busin glide in patients with iridocorneal endothelial (ICE) syndrome. The results show that both techniques were successful in delivering the graft and improving visual acuity. However, the injector group had significantly less endothelial cell loss compared to the Busin group. No surgery-related complications were observed in either group. The use of a graft injector may offer safer and more successful graft attachment without the need for anterior chamber irrigation.
Purpose: To report the outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) performed in iridocorneal endothelial (ICE) syndrome patients using the intraocular lens injector (injector), in comparison with those using the Busin glide. Methods: In this retrospective, interventional comparative study, we evaluated the outcomes of DSAEK performed using the injector (n = 12) or the Busin glide (n = 12) for patients with ICE syndrome. Their graft position and postoperative complications were recorded. Their best-corrected visual acuity (BCVA) and endothelial cell loss (ECL) were monitored over a 12-month follow-up period. Results: DSAEK was conducted successfully in the 24 cases. The BCVA improved from the preoperative 0.99 +/- 0.61 to 0.36 +/- 0.35 at 12 months after operation (p < 0.001), with no significant difference between the two groups (the injector group and the Busin group) (p = 0.933). ECL at 1 month after DSAEK was 21.80 +/- 15.01% in the injector group, which was significantly lower than 33.69 +/- 9.75% of the Busin group (p = 0.031). No surgery-related complications were observed in the 24 cases intraoperatively or postoperatively except that one case suffered from postoperative graft dislocation, without statistical difference between the two groups. Conclusions: At 1 month after surgery, the use of graft injector for delivering DSAEK-based endothelial graft may cause significantly less endothelial cell damage than the pull-through technique used in the application of Busin glide. The injector allows safe endothelial graft delivery without the need of anterior chamber irrigation, which increases the ratio of successful graft attachment.
