Cataracts affect nearly 22 million Americans age 40 and older. By age 80, more than half of all Americans have cataracts. (Source: American Academy of Ophthalmology; Report Title: Eye Statistics at a Glance; Last Updated: May, 2009: URL: http://www.aao.org/newsroom/press_kit/upload/Eye-Health-Statistics-June-2009.pdf). The good news is that treatment for senile cataract is a relatively safe and effective procedure in the mainstream and conventional medical system.
The preferred option for those in the initial stages of a cataract is to rectify their vision using eyeglasses backed by supplements and medicines such that the immediate requirement for surgery is averted. In the due course of time and as the cataract "ripens" to make the lens more unclear for vision or the time when symptoms of haze, glare and opacity are aggravated, surgery may be recommended. The surgery is now done with laser and is minimally invasive and safe. It also has a short recovery time. The surgery removes the opaque lens and a clear artificial lens replaces it.
Surgery as a treatment for cataract has a high success rate as more than nine out of 10 patients enjoy a complete restoration of vision. It is classified as a routine or minor surgery and is performed in the outpatient department of hospitals. It involves the use of local anesthesia. It is a preferred option of treatment for persons over 65 years of age.

Though complications may arise after a cataract surgery such as that of detachment of the retina, corneal edema, or opacification of the posterior capsule, the chances of such occurrences are very slim due to improved technology and precision instruments.
Surgery can be either an intra-capsular extraction procedure or extra-capsular extraction procedure, depending upon the nature and location of the cataract. Intra-capsular extraction involves removal of the lens capsule along with the eye lens.
