Cataract surgery is typically a straightforward, uncomplicated procedure. Because cataracts are considered a normal part of aging and our expected lifespans are increasing with advances in medicine, the number of cataract surgeries performed every year in the US is approaching the 4 million mark. That’s a lot of cataract extractions.
A cataract is an opacity in the lens of the eye. Usually this lens is clear and transparent so that light can easily pass through to reach the back of the eye to form vision. Various factors can underlie the development of a cataract – age is the main one, but other factors such as environment, lifestyle choices, certain medications, systemic diseases, and trauma, can also contribute to the formation of a cataract in the eye.
