Summary

This study compares two methods of removing the outer layer of the cornea during PRK laser eye surgery. One method uses a laser to remove the layer, while the other uses a manual tool. The goal is to see which approach leads to better vision and faster healing. About 100 people aged 18-40 with mild to moderate nearsightedness will take part.
