What are Cataracts?

cataract eye A cataract is a cloudiness found on the lens of the eye that leads to impaired vision. Cataracts occur when there is a buildup of protein in the lens causing this cloudiness which prevents light rays from clearly passing through the lens. The result is  loss of vision. Cataracts take time to form, and symptoms rarely occur until the cataract is clearly noticeable due to a clear blockage of light. Symptoms may include: • Cloudy or blurry vision • Progressive near-sightedness known as “second sight” • Changes in color perception • Trouble driving due to the glare of headlights • Double vision Cataracts occur at various ages for many reasons. The main reason they form is due to the normal aging process. Other factors that influence the formation of cataracts include certain medications, diabetes, and trauma. Types of cataracts include: • Age-related cataracts – Develops as a result of aging. • Congenital cataracts – Babies are born with cataracts as a result of infection, injury or poor development. • Secondary cataracts – These are a result of other medical conditions. • Traumatic cataracts – These form after injury to the eye. Cataracts are diagnosed through an eye examination for vision analysis, as well as pupil dilation to examine the condition of the lens and other parts of the eye. Upon diagnosis, the treatment of choice is cataract surgery. The surgery is quick and easy; it entails removing the cloudy lens of the eye and replacing it with a synthetic plastic intraocular lens implant (IOL). The lens is uniquely made depending on the patient’s visual need. The surgery is 99% successful with minimal complications.   Cataracts do not recur if surgery is perform
