Purpose: To assess the feasibility of a surgical technique and present the preliminary safety results of a new glaucoma device devoid of a tube in painful blind eyes. Methods: Fifteen end-stage glaucomatous eyes without light perception vision were treated with a novel laminar drainage implant. Intraocular pressure was measured preoperatively and up to 24 months after surgery using a Goldmann applanation tonometer. A scale ranging from 0 to 10 was used to evaluate ocular pain. Conjunctival hyperemia, discharge, erosion or retraction, 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. Anterior segment optical coherence tomography was also assessed.
