Incidence of Glaucoma after Combined Descemet's Stripping Endothelial Keratoplasty and Retropupillary Fixated Iris-Claw Lens.

Abstract

To assess the incidence of glaucoma after combined Descemet's stripping endothelial keratoplasty (DSEK) and retropupillary fixated iris-claw intraocular lens (IOL) implantation in the patients with bullous keratopathy (BK) who required secondary IOL or IOL exchange. In this retrospective case series, medical records of 22 patients who underwent combined DSEK and retropupillary fixated iris-claw IOL implantation were evaluated. Preoperative vision, intraocular pressure (IOP), postoperative IOP at different time periods, and intraoperative and postoperative complications were analyzed. A total of 22 eyes of 22 patients (7 females and 15 males) were analyzed. The median age was 62 years, and the median duration of the postoperative follow-up was 106.5 days. The corrected distance visual acuity improved from a median of 1.85 logMAR to 1.68 logMAR. None of the patients had intraoperative complications. Three patients (13.6%) had dislocation of the donor tissue on the 1st postoperative day and were successfully rebubbled. Six eyes (27.3%) had graft failure and required penetrating keratoplasty. Eleven eyes (50%) had a sustained rise in the IOP, of which 2 (9.09%) had ocular hypertension and 9 eyes (40.9%) progressed to glaucoma. DSEK combined with retropupillary fixated iris-claw lens is a good surgical option for the management of aphakic/pseudophakic BK in patients who require secondary IOL or IOL exchange. Regular IOP monitoring after the surgery is an essential, as there is a risk of IOP rise and glaucoma in the postoperative period. Clinicians should be vigilant and control the IOP to prevent glaucoma progression.
