PRCIS: Deep sclerectomy (DS) with the Esnoper Clip® drainage implant in patients with uncontrolled primary open-angle glaucoma (POAG) achieved a complete success rate of 87.2% at the one-year follow-up. PURPOSE: To investigate the efficacy and safety of DS followed by Esnoper Clip® implantation in patients with uncontrolled POAG. METHODS: In a prospective, consecutive, interventional study, we investigated 39 eyes of 35 patients with uncontrolled POAG who underwent DS with Esnoper Clip® implantation. Complete ophthalmologic examinations including corrected visual acuity (BCVA) and intraocular pressure (IOP), were performed preoperatively, and at 1 day, at 1 week as well as at 1, 3, 6, 9 and 12 months postoperatively. Moreover, any goniopunctures and glaucoma medications required postoperatively were noted. RESULTS: The mean preoperative IOP was 20.8±5.2 mm Hg and it decreased to 13.9±3.1 mm Hg at one year postoperatively (P<0.001). The number of glaucoma medications decreased from 2.9±0.7 preoperatively to 0.3±0.8 after one year (P<0.001). The complete success (CS) rate (IOP≤21 mm Hg without glaucoma medication) and the qualified success (QS) rate (IOP≤21 mm Hg with or without glaucoma medication) were 87.2% and 94.9%, respectively. Goniopuncture was performed in 33.3% of cases. No significant BCVA changes were registered at the final follow-up. Perioperative complications consisted of 3 micro-perforations of the trabeculo-descemet membrane. Postoperative complications included: hyphema (6 eyes), hypotony (6 eyes), shallow anterior chamber (3 eyes), choroidal detachment (4 eyes)-all of which were resolved without surgical intervention during the first postoperative month--and conjunctival dehiscence, which required re-suture (2 eyes). CONCLUSION: Deep sclerectomy with the Esnoper Clip® implant was safe and effectively lowered intraocular pressure in patients with uncontrolled primary open-angle glaucoma.
