Intraocular Surgery and Lenses

Intraocular surgery encompasses the techniques used to remove a clouded natural lens and replace it with an artificial intraocular lens, most commonly to treat cataracts, which remain the leading cause of reversible blindness worldwide. Modern approaches such as phacoemulsification—which uses ultrasound to break up the lens before removal—and femtosecond laser-assisted surgery have made the procedure faster and more precise, while sutureless fixation methods have reduced recovery time and complication rates. A persistent challenge is posterior capsule opacification, a condition in which residual lens epithelial cells proliferate on the capsule membrane after surgery and gradually cloud vision again, effectively undoing the procedure. Ongoing research focuses on understanding how to suppress that cellular regrowth, protecting the delicate corneal endothelium from surgical trauma, managing pressure-related complications like glaucoma, and adapting techniques for higher-risk populations such as children, whose eyes continue to develop after the operation.
