Artificial lenses (IOLs) are implanted in the eye to replace natural lenses for patients with cataracts, presbyopia or severe refractive errors. Until recently, IOLs were only available to correct distance vision.
Crystalens® is a new cataract replacement lens (IOL) that works naturally with muscles in the eye to retain the eye’s ability to “accommodate” – shift focus between nearby and distant objects – after cataract surgery. It is the first FDA-approved accommodating lens. With other IOLs, patients lose this ability and require corrective measures such as glasses or contact lenses. Crystalens can treat both cataracts and presbyopia.
Unlike rigid lenses, the flexible silicone Crystalens features hinges that allow it to move with the eye’s muscles and accommodate seamlessly, thereby reducing or eliminating the need for vision correction.
The Crystalens is implanted using the same, nearly risk-free cataract surgery techniques as with other IOLs.
Toric IOLs are specially designed for patients with astigmatism. Traditionally, surgical correction of astigmatism required making a series of small incisions (called LRIs, or limbal relaxing incisions) around the cornea to make it more spherical instead of football-shaped. Implanting toric IOLs often improves vision without the need for these extra incisions, and also allows patients to enjoy a faster, more comfortable recovery.
Traditionally, when a cataract develops, the eye lens is replaced with an artificial intraocular lens (IOL). The lens is usually focused for distance vision, requiring that the patient need to wear reading glasses or contact lenses to focus in on nearer objects.
Through recent advancements in lens technology, an IOL is now available that can provide the patient with a greater range of vision while reducing the need for glasses and contacts. The ReSTOR intraocular lens provides a full range of functional vision for patients that desire a significant decrease in their dependence on glasses or contacts.
