ClinConnect Summary

This clinical trial is looking at how different types of laser eye surgery can affect vision quality in people with low to moderate nearsightedness (myopia). Specifically, the study will compare three types of surgeries: conventional LASIK, Femto-LASIK, and PRK. The goal is to see how these procedures change higher-order aberrations, which are small imperfections in the eye's optical system that can impact vision quality.

To participate in this trial, individuals should be between 18 and 45 years old and have either low myopia (less than -3 diopters) or moderate myopia (between -3 and -6 diopters) without any significant astigmatism. Certain conditions, such as previous eye surgery, certain eye diseases, pregnancy, and lactation, may prevent someone from joining. If eligible, participants will receive one of the three treatments and be monitored for changes in their vision quality. This study aims to help improve outcomes for people seeking laser vision correction.
