Normal vs cloudy lens |
More than 50% of people over the age of 60, and a large percentage of those younger, have vision that is impaired by cataracts. A cataract is a clouding of the normally clear lens of the eye. Cataracts are so common that everyone will eventually develop a cataract if they live long enough. Vision loss from cataracts is gradual, which is why many patients have difficulty noticing the early symptoms. The length of time for a cataract to develop can vary from a few months to several years. Patients with cataracts usually describe a blurring or clouding of their vision and in later stages may describe it as seeing through a piece of wax paper. Some report poor night vision, double vision in one eye, or a sensation that one just cannot get enough bright light to read. Glare and difficulty with night driving are also commonly caused by cataracts.
Currently, there is no medical treatment to reverse or prevent the development of cataracts. Once they form, there is only one way to achieve clear vision again, and that is to surgically remove the cloudy, natural lens of the eye (using ultrasound and a no-stitch incision), and replacing it with a permanent lens implant.
There are two different types of permanent lens implants: distance vision only (which necessitates the use of reading glasses after surgery for mid-range and close work; otherwise known as Standard Monofocal Vision Implants) and "Smart Lens" Implants, which offer patients binocular multifocal vision (which eliminates the need for glasses for both distance and near vision). The physicians at are experienced in implanting both types of lenses.
