Laser assisted cataract surgery uses precision femtosecond lasers to make corneal incisions, perform the anterior capsulotomy, and fragment the lens. The cataract itself is not removed by the laser; it is still extracted using traditional surgical techniques. Some surgeons and optometrists believe lasers can offer extra precision, but experienced surgeons can achieve excellent results without them. Laser assisted cataract surgery is usually more expensive than traditional surgery and is not available on the NHS, though both methods are highly effective and safe.
