Eye transplant showdown: which corneal procedure gives better vision?

NCT ID NCT06818747

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two types of corneal transplants—PKP and DSAEK—in 334 adults aged 50+ with advanced bullous pseudophakic keratopathy, a condition where the cornea swells and blurs vision. Participants are randomly assigned to one procedure and followed for 2 years to see which provides better visual acuity. The goal is to identify the more effective surgical option for restoring sight.

What this could lead to

If this trial succeeds, it could show which corneal transplant method gives better vision recovery for people with advanced bullous keratopathy.

What could go wrong

This is a comparative effectiveness trial, not a test of a new drug. Results may not apply to all patients, and both procedures carry risks like graft rejection or infection.
