A cataract is an eye condition that is a leading cause of visual impairment. Cataracts are caused by old age, injuries, surgery, and congenital birth conditions. Cataracts are a protein buildup that forms in the eye lens and prevents light from entering the retina. Patients with cataracts see halos, faded colors, misty vision, and poor visibility in low light. Light Adjustable Cataract Implant Lenses are special lenses used to aid vision after cataract-removal surgery. Light adjustable lenses (LALs) are made with special material whose optical power is adjustable to the patient’s needs.
Cataracts are progressive and without treatment, they will get worse until they reach a point where your vision is so poor you can be considered blind. Fortunately, there is an effective solution for cataracts. Cataract surgery removes the clouded lens and replaces it with an artificial alternative - an intraocular lens, or IOL. An IOL is an artificial replacement for the natural lens of your eye. Made from clear plastic, there are several different types, and which is right for you will depend on your individual circumstances.
