During cataract surgery, the surgeon carefully removes the eye's natural clouded lens while leaving the delicate outer capsule—known as the capsular bag—intact. The replacement intraocular lens, such as a light-adjustable lens, is then folded and inserted directly into this natural capsular bag. Over the subsequent weeks of healing, the natural tissue of the eye grows and seals securely around the haptics and structure of the artificial lens, permanently locking it into the correct anatomical position for stable long-term vision.
