Advanced Lens Options
Intraocular Lenses (IOLs)
An Intraocular Lens (IOL) is an artificial lens that is implanted in your eye during cataract surgery to replace the natural lens that has developed a cataract. Until recently, nearly everyone received basically the same type of intraocular lens.
Today, advances in technology have led to new types of IOLs – even ones that can correct presbyopia and astigmatism (toric lenses). Dr. Young will review the benefits of each IOL and help determine the type that is right for you.
New Advanced Technology IOLs
New Advanced Technology IOLs can do even more than just cure cataracts. For many patients, they can correct additional vision problems and offer excellent near, intermediate, and distance vision without the need for glasses or contacts. Depending on the health of your eye and your vision needs, the surgeon will work closely with you to determine the best IOL for your eye prior to the procedure.
The Young Eye Institute offers the most advanced IOLs now available:
Extended Vision IOLs
Multifocal IOLs make it possible to see far and near more clearly. On the surface of the lens, there is usually a form of concentric rings etched onto it. This allows objects at a variety of distances to focus on the retina. They rely on the eye muscles to move when necessary to focus. Multifocal IOLs often allow you to stop wearing eyeglasses or contact lenses.
Astigmatism Correcting IOLs
Astigmatism is a common problem affecting about 1 in 3 adults. In this condition, due to the shape of the cornea or eye itself, light that enters the eye is not uniformly refracted and light rays are bent causing a blur to the vision. In the past, intraocular lenses (IOLs) used in cataract surgery could not correct astigmatism. However, special Toric IOLs have been developed to more predictably correct astigmatism during cataract surgery. Toric IOLs have special markers on the peripheral parts of the lens that enable the surgeon to see the orientation of the astigmatism correction in the lens. Once the toric IOL is implanted in the eye, the surgeon then rotates the lens so the astigmatism correction is properly aligned for best results.
Monofocal IOLs are the most common type of lens used in cataract surgery. As the name implies, a monofocal IOL has one focusing distance. It can be set to focus for near, intermediate, or distance vision. Most patients choose to have them set for clear distance vision, and they wear eyeglasses for some tasks such as reading, sewing or computer work.
