A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, and halos around light, trouble with bright lights, and trouble seeing at night. This may result in trouble driving, reading, or recognizing faces. Poor vision caused by cataracts may also result in an increased risk of falling and depression. Cataracts are the cause of half of blindness and 33% of visual impairment worldwide. These are most commonly due to aging but may also occur due to trauma or radiation exposure, be present from birth, or occur following eye surgery for other problems.
Form of Management:
Medical Management - The incidence of cataract continues to increase with the ageing of the population. Surgical treatment with phacoemulsification and intraocular lens implantation remains the only proven treatment. In Phaco news tech is (Micro incision cataract surgery) which required only 2 mm incision for surgery. In IOL (Intra Oculus Lens) news like Aspheric Optic, Yellow AO, Toric, Multifocal, Trifocal.
Surgical Management - Some anti-cataract drugs, such as carnosine, have now reached clinical trials and showed encouraging results that warrant further investigation.
