SUMMARY
Purpose: To report a case of pseudophakic bullous keratopathy (PBK) after small-incision Descemet stripping endothelial keratoplasty (DSEK).
Methods: In this prospective, non-randomised, consecutive, interventional case, the corneal endothelium was selectively replaced by the DSEK technique in eye with pseudophakic bullous keratopathy (PBK). One eye was treated in Zarifa Aliyeva Eye Centre from 26 September 2009 up to present time. Descemet membrane and endothelium were stripped from the recipient and an 8-mm diameter donor button consisting of posterior stroma and healthy endothelium was folded and implanted through a 5-mm incision. An air bubble was used to press the donor tissue against the recipient cornea, allowing it to attach without sutures.
Results: A 52-year-old man underwent DSEK for pseudophakic bullous keratopathy in his right eye after phacoemulsihcation some years ago. Healthy donor cornea with a cell count of 3067 cells/sq. mm was considered for transplantation. Follow-up was less than 1 month (3 weeks). Preoperative best-corrected visual acuity (BCVA) was 0.03. The BCVA 4th day after surgery 0.08. The 3rd week after surgery BCVA 0.1.
Conclusions: Compared to standard penetrating keratoplasty,DSEK causes minimal refractive change and provides rapid visual recovery for patients with endothelial dysfunction. This technique maintains the structural integrity of the cornea by preserving the recipient’s epithelium, Bowman’s layer, and entire stromal thickness.
