A cataract is the clouding of the lens in the eye. Normally, light passes through the clear lens and is focused onto the retina. However, as a result of the natural aging process, the lens gradually becomes cloudy and this blocks the passage of light through the eye causing distorted or blurred vision. The most effective way to restore vision is to remove the cloudy cataract and replace it with a synthetic lens implant (Intraocular lens or IOL). With recent advances in cataract surgery equipment and techniques, vision can be restored more safely and faster than ever, allowing patients to resume normal activities within hours after surgery (some activities may be limited during healing). Using these state-of-the-art techniques, cataract surgery is easier than ever and may reduce or eliminate spectacle correction for distance vision.
