Laser touch-up after cataract surgery: can Relex-Smile fix leftover nearsightedness?
NCT ID NCT04693663
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial tests whether Relex-Smile laser surgery can safely and effectively correct residual nearsightedness in people who still have blurry distance vision six months after cataract surgery. Participants will undergo the laser procedure and have their vision and refraction measured afterward. The study aims to see if this approach can improve visual acuity without the need for glasses.
