Cataract surgery restores clear vision because the cloudy, rigid, human lens is removed and replaced by a synthetic intraocular lens, usually called an “IOL.”
Advanced Technology Implants
Patients with standard “fixed-focus” IOLs typically need a weak pair of bifocals following surgery. These IOLs provide excellent overall clarity especially when fine-tuned by the use of bifocals. These IOLs are covered by insurance as part of the costs of standard cataract surgery.
Premium Presbyopia and astigmatism correcting IOLs
Many people who have cataracts experience other problems with their vision, such as presbyopia and astigmatism, which the Symfony lenses also address. Presbyopia, which affects most people over age 40, means people have lost the ability to focus on objects up close and often require glasses to perform near visual tasks. Astigmatism is when the cornea is misshapen, which causes blurry or distorted vision.
During cataract surgery, the natural lens of the eye is removed, and an artificial lens, called an intraocular lens, or IOL, is inserted into the eye. The IOL most commonly used in cataract surgery is a monofocal lens, which only allows the person to see at a distance, with closer objects being out of focus. In contrast, the Symfony lens was specifically developed with features to improve both the range and quality of vision.
