Descemet stripping endothelial keratoplasty using Busin technique to minimize endothelial cell loss

Introduction
To present the results of endothelial keratoplasty (DSEK) using „Busin” technique performed from September 2008 to December 2008 in Ophthalmology Department, District Railway Hospital in Katowice.

Material and methods
7 patients (7 eyes) underwent DSEK using “Busin glide” technique, due to the corneal edema after cataract phacoemulsification. Best corrected visual acuity, central corneal thickness, endothelium cell density were assessed three and six month postoperatively.

Results
Mean time period between cataract surgery to DSEK was 15.8 month (from 11 to 37 months). The mean central corneal thickness before surgery was 750 μm (from 690 μm to 850 μm), mean best corrected visual acuity 0.001 (from light perception to 0.01). The average best corrected visual acuity three months after surgery was 0.4 (0.1 to 0.6), and 0.5 (from 0.1 to 0.7), six months. Mean central corneal thickness 3 months postoperatively equaled 790 µm (from 714 µm to 850 µm), and a sixth month was 659 µm (from 800 µm to 604 µm). Three months after DSEK, mean endothelium cell density was 2640/ mm2 (from 2301/ mm2 to 2904/ mm2), six months after DSEK the average endothelial cell density equaled 2430/ mm2 (from 2210/ mm2 to 2780/ mm2). Disc dislocation was not observed in studied group.

Conclusions
The use of BG as a donor lenticule insertion technique in DSEK technique seems to be a safe support of this lamellar surgery.
