OBJECTIVE: To assess the feasibility of a novel surgical technique in painful blind eyes. DESIGN: A prospective safety study conducted at the Federal University of Minas Gerais, Brazil. PARTICIPANTS/SAMPLES: A total of 15 end-stage glaucomatous eyes without light perception vision. METHODS: After implantation, conjunctival hyperemia, discharge, erosion, aqueous humor leakage, corneal edema, hyphema, anterior chamber cells and depth, dislocation of the implant, and filtering bleb height were assessed by slit-lamp biomicroscopy. Intraocular pressure was measured preoperatively and 24 months following surgery. A numerical rating scale was used to evaluate pain. Anterior segment optical coherence tomography was also assessed. RESULTS: Laminar drainage implant surgery was performed in all patients without major complications. Mean intraocular pressure was significantly reduced after surgery without hypotensive medication (preoperatively 54.5 ± 5.1 mmHg vs 24 months after surgery 37.0 ± 15.4 mmHg, p = 0.003). Subjective ocular pain intensity also reduced (preoperatively 10 vs at 24-month follow-up visits 0). Corneal edema incidence reduced from 85.7% (95% confidence interval: 57.2%-98.2%) to 16.7% (95% confidence interval: 2.1%-48.4%) at the 24-month follow-up. No patients experienced a prolonged flat anterior chamber or erosion of overlying tissues. CONCLUSION: The surgery was feasible and safe in painful blind eyes.
