Cataracts
One of the most common eye problems among seniors, the development of cataracts can cause vision problems and vision loss. A cataract is a painless clouding of the lens in the eye that causes blurry vision.
It progresses slowly as we age. Causes of cataracts include aging, diabetes, trauma, some medications, and excessive UV light exposure.
Your doctor can see a cataract while doing a routine eye exam. Surgery is curative as the cloudy lens is removed and replaced with an artificial one, called an IOL or intraocular lens. There are many types of Intraocular lens and will determine where the eye is in focus following surgery.
New developments in cataract surgery allow for IOL s that correct both near and distance vision, reducing or even eliminating the need for glasses after the operation. Conventional "monofocal" lenses only correct one focal distance, so people still need reading or driving glasses after surgery. So-called "toric" implants are available to correct astigmatism. Multifocal and or Extended depth of focus lens “ Symfony”correct distance and near and some also astigmatism, to reduce dependence on glasses.
