Could a tiny ring improve cataract surgery for RP patients?

NCT ID NCT07126470

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

Summary

This study tests whether placing a capsular tension ring (CTR) during cataract surgery helps keep the artificial lens more stable in people with retinitis pigmentosa (RP). Each of the 88 participants will get the ring in one eye, while the other eye serves as a comparison. Researchers will measure lens position, vision, and complications after surgery.
