PURPOSE: To analyze the functional and anatomic outcomes of management of Descemet membrane detachment after phacoemulsification using a protocol based on the detachment's height, extent, and chord length and its relation to the pupil. SETTING: Dr. Agarwal's Eye Hospital and Eye Research Centre, Chennai, India. DESIGN: Prospective comparative case series. METHODS: Eyes with post-phacoemulsification Descemet membrane detachment were managed surgically or medically based on the detachment's height, extent, length (chord), and relation to the pupil (HELP protocol). Central corneal thickness (CCT), chord length, and detachment height were determined by anterior segment optical coherence tomography (AS-OCT) (Visante). RESULTS: Of 161 eyes, 96 were treated surgically (Group 1) and 65 medically (Group 2). The mean length and mean height of Descemet membrane detachment were 2.4 mm ± 1.4 (SD) and 266 ± 189.8 μm, respectively, in Group 1 and 1.03 ± 0.4 mm and 153.3 ± 60.8 μm, respectively, in Group 2. The complete reattachment rate was 95.8% in Group 1 and 96.9% in Group 2. The corrected distance visual acuity (CDVA) was 20/40 or better in 83.3% of eyes in Group 1 and 92.3% of eyes in Group 2. No eye lost CDVA as a result of a Descemet membrane scar in the central 5.0 mm of the cornea. The AS-OCT allowed visualization of the detachment in all eyes with a CCT of more than 800 μm. There was no difference in the final CDVA between Group 1 and Group 2. CONCLUSIONS: The AS-OCT-based algorithm was effective for managing post-surgical Descemet membrane detachment in eyes with dense corneal edema. Early surgical intervention for detachments in the central cornea can reduce scarring-induced visual loss.
