NCT ID NCT05072977

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

Summary

This study compared two methods of removing the clear outer layer of the eye (the epithelium) during laser vision correction for nearsightedness and astigmatism. One method uses a laser, the other uses alcohol and manual scraping. The goal was to see which approach leads to less corneal haze, better vision, and less pain. The study included 71 people and used a special software to measure haze from eye scans.
