This condition develops when the eye's natural lens focusing system grows more rigid and can no longer move or change shape sufficiently enough to enable sight at all distances.If you receive a standard IOL during your procedure instead of one that corrects or minimizes presbyopia, you may have great distance vision but likely would need reading glasses following cataract surgery.AO Lens is an artificial lens implant that can treat both a person's cataracts and presbyopia —the clouding or hardening of your lenses, and the loss of near and intermediate vision, respectively. Like the natural lens, it is a lens implant that uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances.Crystalens dynamically adjusts to your visual needs.In past years, intraocular lenses (IOLs) were fixed focus (monofocal) only, usually fixed for distance vision.They were used to treat cataracts in a Clear Lens Exchange (CLE).Using three different technologies, they provide focused vision in distance, near and mid-ranges, and are used to correct both cataracts and .
They increase its curvature for light coming from far objects, and flatten it for light coming from nearby objects.
Visit During cataract surgery, your physician will replace your natural lens with an IOL.
Today there are multiple types of IOLs, each delivering a different performance profile based on how the lens is designed.
The Crystalens IOL shifts its position to adjust with the action of eye muscles and movement to improve eyesight.
A Crystalens is ideal because, beginning at around middle-age, most people lose the ability to see at multiple distances due to the occurrence of presbyopia, an age-related condition that necessitates the use of reading glasses.
