Q. What are cataracts and how can they be treated?
A. Cataracts are a clouding of the eye’s natural lens which leads to a decrease in vision over time. Symptoms include difficulty driving at night, foggy vision and glare. Cataracts are most commonly caused by aging but can also be caused my certain medications, trauma, exposure to UV radiation or rarely congenital. Ways to prevent the development of cataracts include wearing sunglasses and not smoking. Early symptoms may be improved with eye glasses but if this does not help surgery to remove the cataract and replace it with a clear implant is the most effective treatment.

Cataracts is a disease of the eye that results in the clouding of the lens of the eyeball. Cataracts prevent clear images from appearing on the eye’s retina; causing mild, moderate, even severe blurred vision.
Typically an eye disorder associated with aging (over half of the people in America over age 80 have either had a cataract or cataract surgery), cataracts generally occur later in life as the lens structure within the human eye changes and gets older.
During the evaluation of your eye health we will carefully examine your lens for signs of cataract formation. If a cataract is noticed and the clouding is causing visual disruption, the optometrist will refer you to a trusted and respected surgeon for surgery, which is the only known cure for cataracts. Our Eye Care Practice will be there for you providing pre and post cataract surgery care.
Cataract surgery is the removal of the natural lens of the eye (also called “crystalline lens”) that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over the time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. During cataract surgery, a patient’s cloudy natural lens is removed and replaced with a synthetic lens to restore the lens’s transparency.
Following surgical removal of the natural lens, an artificial intraocular lens implant is inserted (eye surgeons say that the lens is “implanted”). Cataract surgery is generally performed by an ophthalmologist (eye surgeon) in an ambulatory (rather than inpatient) setting, in a surgical center or hospital, using local anesthesia (either topical, peribulbar, or retrobulbar), usually causing little or no discomfort to the patient. Well over 90% of operations are successful in restoring useful vision, with a low complication rate. Day care, high volume, minimally invasive, small incision phacoemulsification with quick post-op recovery has become the standard of care in cataract surgery all over the world.
