<unk>  (abbreviated PRX, trade name Catalin) is a medication used in the possible treatment and prevention of cataracts. A report in the journal of Inorganic Chemistry showed that in liquid solutions<unk>  could cause decreased cloudiness of a crystallin solution produced to mimic the environment of the eye.<unk>  interacts with selenite or calcium ions that have been proven as factors leading to the formation of lens cataract.<unk>  reduces the cloudiness of the lens solution containing calcium by 38% and reduced the cloudiness of the selenite solution by 11%.
