Abstract

To evaluate the occurrence of localized incision-site Descemet membrane detachment (DMD) during and after phacoemulsification and to study its relationship with phacoemulsification parameters. Forty-three, consecutive uneventful cases of phacoemulsification through 2.8-mm clear corneal incision were included in this prospective study. Preoperatively, the grade of cataract was assessed. The phacoemulsification parameters noted were phacoemulsification time, aspiration time, cumulative dissipated energy (CDE), ultrasound time, and total fluid volume. Anterior segment optical coherence tomography (AS-OCT) was performed on postoperative days 1 and 7 to study the course of the incision-site DMD. Fourteen of 43 cases (32%) showed localized incision-site DMD either intraoperatively or on AS-OCT on the first postoperative day. Of these, nine cases were detected intraoperatively, and six cases were detected on AS-OCT on the first postoperative day. All cases were of planar type and resolved spontaneously. A single case showed a concurrent DMD involving central cornea, which resolved without any surgical intervention. The occurrence of DMD was significantly higher in those with the total ultrasound time greater than 60 sec (P=0.038) (odd...Continue Reading
