Cataract removal

Alternative names:

Cataract Removal - A procedure to remove the clouded lens (cataract) of the eye to improve vision.

Definition:

Procedure to remove the lens of the eye that has become clouded (cataract) to improve vision.

Description:

The normal lens of the eye is transparent and focuses images on to the retina to create a visual representation. As cataracts develop, however, progressive opacity blocks the normal path of light entering the eye such that vision becomes obscured. The purpose of cataract surgery is to remove the clouded lens in order to create an unobstructed pathway for light, thereby restoring clear vision.

While children may be born with clouded lenses (congenital cataracts). due to infections in utero, cataracts are seen most commonly in the elderly as a result of the normal aging process.

Surgery is the treatment usually recommended for people who have loss of vision (visual abnormalities) caused by cataracts. Cataract removal is not urgent; rather, the main indication is dissatisfaction with current vision, or compromised quality of life due to visual impairment.

Indications:

Cataract surgery is usually recommended for people who have loss of vision (vision abnormalities) caused by clouding of the lens.
