Summary
This study tested the safety and effectiveness of the EVO/EVO+ Visian Implantable Collamer Lens (ICL) in 327 adults with moderate to high nearsightedness (with or without astigmatism). The lens is surgically placed inside the eye to correct vision. Researchers tracked side effects, eye cell health, and vision changes over 6 to 36 months. The goal was to see if the lens is a safe and reliable option for vision correction.
