A cataract is a condition when the lens in the eye is clouded, resulting in blurry vision or loss of vision. The clouding is caused by changes to the lens in the eye which prevent transmission of light. As the cataract develops, the clouding becomes denser and blocks the light that passes through the lens. Your vision becomes blurred as a result. Cataracts are usually linked with aging and can develop slowly in one or both eyes. Other medical diseases, such as diabetes and injury to the eyes may also cause cataracts to form.
Visual Acuity Tests
An eye chart measures how well a series of letters can be read, to determine if your vision is 20/20 or if there are signs of impairment.
Slit Lamp Tests
Intense light is used to illuminate the cornea, iris, lens, and the space between the iris and cornea. This allows for abnormalities in these structures to be detected.
Retinal examination
Eyedrops are used to dilate the pupils of the eye to help with examining the retina for signs of cataract.
