Abstract

Background: Keiki Mehta BP valve is a glaucoma drainage device based on the mechanism of body pressure.

Purpose: To evaluate the efficacy of Keiki Mehta valve implantation in refractory glaucoma.

Methodology: Prospective, interventional, institution-based study. Adult patients with refractory glaucoma who underwent Keiki Mehta valve implantation from May 2019 to December 2019 were followed up to 18 months.

Results: 20 patients (20 eyes) after Keiki Mehta valve implantation were followed up on post-operative day 1, 1, 3, 6, 12 and 18 months. Visual acuity, intraocular pressure (IOP), anti-glaucoma medications and success rate were measured at every visit. There was significant reduction in mean IOP from preoperative visit at every postoperative follow up (p<0.05). Kaplan-Meier survival analysis showed a probability of 50% complete success and 20% qualified success at 18 months. Conclusion: Keiki Mehta valve implantation is an effective and safe treatment for refractory glaucoma.
