The recipient of an MD from the University of Maryland school of medicine in Baltimore, Dr. Anthony Roberts is an eye physician and the founder of Shady Grove Ophthalmology. Dr. Anthony Roberts has experience performing refractive surgeries like LASIK and surgically treating eye diseases with laser cataract surgery. An eye disease that interferes with visual function, cataract is an abnormal clouding of the lens. Worldwide, this disease is the leading cause of impaired visual activity and blindness. Often, patients with the condition seek treatment to regain proper vision. In the human eye, the lens is positioned behind the iris (the colored part of the eye that surrounds the pupil). Physiologically, the lens focuses light on the retina to produce clear images. Age and certain medical conditions can deteriorate the tissues in the lens, causing them to clump together. As the disease progresses, the clouding becomes denser and occupies more of the lens area. The clouding hinders light from reaching the retina through the affected area of the lens, which results in blurred vision. In some cases, cataract is present right from birth or develops during early childhood due to factors like genetics and intrauterine infection. In most cases, a cataract is corrected with a surgical procedure called cataract surgery. Essentially, this treatment replaces the damaged lens with an artificial lens. Many ophthalmologists (eye doctors) are trained in the procedure and offer the treatment on an outpatient basis.
