The lens is the structure in the eye which changes shape to allow objects to be seen clearly. This process is called accommodation. The lens is responsible for a great deal of the eye's ability to see clearly.
If the lens becomes cloudy, the person is said to have a cataract. In most cases, cataracts can be removed with very little risk. In fact, cataract surgery is an outpatient procedure. For more information about cataracts, visit the cataract links library.
People who have had cataract surgery may wear powerful glasses or contact lenses. If the other structures of the eye are in good condition, these people will have fairly normal vision while wearing their corrective lenses. Most people also receive an intraocular lens (IOL), an artificial lens which is implanted in the eye after the cataract is removed.
Post-cataract patients may experience difficulty with glare in certain conditions. Sunglasses or tinted lenses may help to cut down on glare.
