NCT06960629 | Completed Phase 2 DMC

• 1 other identifier: 2025/0327-4

Brief Summary

The goal of this clinical trial is to learn if topical netarsudil/latanoprost works to treat pseudophakic bullous keratopathy in patients with glaucoma. The main questions it aims to answer are: Does topical netarsudil/latanoprost improves visual function in patients with glaucoma and pseudophakic bullous keratopathy? Does topical netarsudil/latanoprost affects the central corneal thickness (CCT) in patients with glaucoma and pseudophakic bullous keratopathy? Researchers will compare topical netarsudil/latanoprost to a placebo (a look-alike substance that contains no drug) to see if topical netarsudil/latanoprost works to treat pseudophakic bullous keratopathy (PBK). Participants will take topical netarsudil/latanoprost or a placebo every day for 12 weeks and visit the clinic once every two weeks for checkups and tests.
