@manju Cataracts are a problem faced by millions of elderly Americans yearly, many of whom will require surgical replacement of their own lens with an artificial one, known as a psuedophakos or intra-ocular lens. These lenses come in many configurations, such as single-focus (like glasses for distance vision), multi-focal lenses (like bifocal glasses), and hi-tech variable-focus lenses (like real eyes). In 2006, the last reporting year, there were over 2.5 million procedures performed — an increase of 43% over 10 years. While the vast majority of cataract surgery is safe and effective, there is a 1%-2% chance of retinal detachment over the rest of the patient’s lifetime. If this occurs and is not treated promptly, patients can completely lose their vision in the effected eye. While researchers are examining non-surgical treatments for cataracts, surgery is currently the only real treatment or cure. The market leader in intra-ocular lenses, Alcon Laboratories, had sales of $1.2 billion in 2010. Alcon recently merged with Novartis.
