Tiny lens left behind may affect vision after laser eye surgery

NCT ID NCT06806085

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at why some people develop higher-order vision distortions after SMILE laser eye surgery when a tiny piece of the removed lens is left in the eye. Researchers will measure changes in the eye's surface shape before and after surgery in 33 people. The goal is to understand what factors cause these distortions, which could help improve future surgeries.
