What is a cataract?
A cataract is a clouding of the eye’s lens behind the iris and the pupil.
•A subcapsular cataract occurs at the back of the lens. People with diabetes have a greater risk of developing a subcapsular cataract.
•A nuclear cataract forms deep in the central (nucleus) of the lens. Nuclear cataracts usually are associated with aging.
•A cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion.
Common Symptoms of Cataracts
•Blurry or foggy vision
•Decreased night vision or see halos around lights
•Colours appear dull or muted
•Your glasses no longer working
•Sunlight or other light seem overly bright
In the early stages of a cataract, where vision is minimally affected, your optometrist can sometimes prescribe new lenses for your glasses to give you the sharpest vision possible. When the cataracts start to interfere with your daily activities and glasses cannot improve this vision, your optometrist will refer you to an ophthalmologist who may recommend the surgical removal of the cataracts.
Surgical Procedure for Cataracts
In addition to referring you to secondary specialists, such as ophthalmologists, for treatment of systemic diseases or eye surgery when necessary, your optometrist also co-manages your treatment of ocular diseases and pre and post-surgical patient care with ophthalmologists.
