Outcomes of descemetopexy with isoexpansile perfluoropropane after cataract surgery

PURPOSE: To report the indications, anatomical outcomes, functional outcomes and limitations of descemetopexy with intracameral injection of isoexpansile perfluoropropane (14% C3F8) in eyes with Descemet's membrane (DM) detachment after cataract surgery. METHODS: This retrospective non-comparative interventional case series included 67 eyes of 67 patients who underwent descemetopexy at a tertiary eye hospital. The procedure consisted of descemet's membrane reattachment by injecting isoexpansile perfluoropropane (14% C3F8)intracamerally. Outcome measures were reattachment of DM, improvement in visual acuity, resolution of corneal edema, causes for failure of DM reattachment and complications. RESULTS: Sixty-seven eyes of 74 patients were analyzed. Phacoemulsification (56.71%) had the highest DM detachment as compared to manual SICS in 19 (28.36%) and ECCE in 10 (14.93%) eyes. Descemetopexy with 14% C3F8 resulted in anatomical reattachment of DM in 71.64% and functional improvement in visual acuity in 74.63% of treated eyes. The location and the extent of DM detachment did not influence DM reattachment. Complete reattachment of DM occurred in all 26 eyes (100%) with planar type detachments, whereas with non-planar type detachments only 22 eyes (53.7%) achieved complete reattachment. CONCLUSION: Descemetopexy with isoexpansile perfluoropropane offers good surgical outcomes regarding visual acuity and resolution of corneal edema.
