Deep sclerectomy with supraciliary hema implant (Esnoper® V-2000): results and complications

The aim was to report the results of deep sclerectomy (DS) with supraciliary hema implant and the influence of the surgical complications on intraocular pressure (IOP). Forty-eight eyes of 41 patients with open angle glaucoma (OAG), who underwent DS with supraciliary hema implant (Esnoper® V-2000), were included in this study. A significant IOP reduction was observed, changing from a preoperative mean of 24.6 ± 6.33 mmHg to 16.5 ± 4.4 mmHg (p < 0.001) at 12 months and 16.1 ± 3.4 mmHg (p < 0.001), at 24 months. Similarly, a significant reduction in the number of glaucoma drugs needed was observed, varying from 2.71 to 0.22 (p < 0.001) and 0.4 (p < 0.001), 1 and 2 years after surgery. Goniopuncture with the Nd:Yag Laser was performed in 30 eyes (62.5 %) with a mean time between the surgery and the procedure of 150 days, producing a mean IOP reduction of 4.0 mmHg (p < 0.001). The main intraoperative complications were microperforation of the trabeculodescemetic membrane (TDM) in 1 eye (2.08 %) The main early postoperative complications were seidel at 24 h in 11 eyes (22.91 %), hyphema in 7 eyes (14.58 %), choroidal detachment in 3 eyes (6.25 %) with macular folds in 2 (4.16 %) and need for additional mitomycin injections in 2 eyes (4.16 %). All these complications were spontaneously resolved. No correlation between these complications and final IOP was found, but a significant correlation between the presence of hyphema and higher IOP 24 months postoperatively (p = 0.048) was observed. DS with supraciliary hema implant is a safe and effective technique for the management of OAG. The presence of hyphema during the first week after the surgery could be considered as a negative prognostic factor in DS with supraciliary implantation.
