Cataract, defined as opacification of the lens inside the eye, is the commonest cause of blindness worldwide. Treatment involves surgical extraction and implantation of a lens implant. We are developing a drug-eluting intraocular lens, which can remove 3 risks associated with surgery: (1) inflammation, (2) infection & (3) clouding of the lens capsule, known as posterior capsular opacification (PCO). Our technology will prevent complications and eliminate the need for eye drops after surgery.
The first drug-eluting intraocular lens implant for patients undergoing cataract surgery.
