Pirenoxine (abbreviated PRX, trade name Catalin) is a medication used in the possible treatment and prevention of cataracts. A report in the Inorganic Chemistry journal s howed that in liquid solutions, pirenoxine could cause decreased cloudiness of a crystallin solution produced to mimic the environment of the eye.
The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the ...

A 2013 American survey involving nearly two million bilateral cataract surgery patients found immediate sequential bilateral cataract surgery was statistically associated with worse visual outcomes than for delayed sequential bilateral cataract surgery; however, the difference was small and might not be clinically relevant.

Approximately 50% of all congenital cataract cases may have a genetic cause which is quite heterogeneous. It is known that different mutations in the same gene can cause similar cataract patterns, while the highly variable morphologies of cataracts within some families suggest that the same mutation in a single gene can lead to different ...
Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [3] Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision.
A cataract is an opacity that develops in the crystalline lens of the eye. [9] The word cataract literally means, "curtain of water" or "waterfall" as rapidly running water turns white, so the term may have been used metaphorically to describe the similar appearance between mature ocular opacities and water fall.
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.
