Cataract extraction is the removal of the clouded crystalline lens.After cataract surgery, vision may be improved with glasses, contact lenses, or an intraocular lens such as crystalens® that is implanted behind the iris where the crystalline lens used to be.The outer membrane is called the cornea, and the inner lens is called the crystalline lens.LASIK and other refractive surgeries are used to correct the curvature of the cornea, as well as corneal implants.The FDA presented this data for crystalens® success based on 497 patients: The placement of intraocular lenses is a new technology, and long-term data is not available.Talk with your doctor and make sure you fully understand the risks involved before deciding if crystalens® is right for you. Should this occur, the lenses will still help you see better at distance but will not help with near vision.There are certain requirements you must meet to have RLE or refractive cataract surgery with Crystalens accommodating lenses. Typically patients who want this lens are over 45 and are experiencing presbyopia.
Also, if the ciliary muscles and zonules that attach to the lens capsule are in particularly poor condition, the procedure may be ineffective.The crystalens® implant works in much the same way as your natural lens.With natural, healthy vision, your eye focuses on images near and far by coordinating the curvatures of its outer membrane and inner lens.Would you like to rid yourself of reading glasses and improve your distance vision at the same time?Are both cataracts and age-related farsightedness (presbyopia) affecting your lifestyle?If you answered yes to either of these questions, accommodating intraocular lens implants (IOLs) may be the solution you’ve been looking for.Accommodating IOLs are used in two procedures: refractive lens exchange (RLE) if you do not have cataracts and refractive cataract surgery if you do.The lens bends, flexes, thickens, and thins as you focus on objects near and far. The accommodation of the lens works to focus images on the retina, where the images are turned into chemical signals which are interpreted by your brain.As you age, your lens loses flexibility and becomes less accommodating.They cannot be used to treat astigmatism, but you can choose to have a separate laser eye surgery procedure to address your astigmatism if you wish. S., only one brand of accommodating IOL is currently available: Crystalens.Check out the following video to learn more, or continue reading about Crystalens risks, costs and candidacy.
