According to the American Academy of Ophthalmology, more than half of all Americans will develop cataracts by age 80. A cataract is a clouding of the lens in the eye which can cause one’s vision to become blurry. They are common with age and can occur in one or both eyes. The clouding usually occurs slowly, but can happen quickly, especially after trauma to the eye. While cataracts are not painful, they do cause many symptoms such as blurry vision, fewer details, glare while driving or reading, dull colors, changes in your glasses prescription and double vision in one eye.
New advancements and techniques have made cataract surgery one of the most successful and life-improving surgical procedures performed. We offer the latest procedures available to help remove cataracts and restore your vision, including the placement of intraocular lenses. Most cataract surgeries are performed on an outpatient basis and more than 98% of surgeries improve vision.
During cataract surgery, the eye’s natural lens is removed and replaced with an intraocular lens, or IOL. Since being approved by the FDA in 1981, IOLs have offered an effective alternative for cataract patients. Prior to the use of IOLs, cataract patients had to wear very thick eyeglasses or special contact lenses in order to see after the natural lenses were removed during surgery.
Types of Intraocular Lenses (IOLs)
Conventional IOLs are only monofocal, offering patients vision at only one distance (typically far), and still requiring them to use corrective lenses for reading and close work. Now there are new multifocal IOLs available which provide patients the ability to see well at more than one distance without the use of glasses or contacts. Other types of IOLs available are Toric IOLs for people with astigmatisms and Blue Light-Filtering IOLs, which help to filter UV light rays.
Multifocal Lens Implants
At Maumee Eye Clinic, we use the AcrySof® ReStor® and Tecnis® multifocal lenses for patients who want to be without glasses as much as possible. With these IOLs, the patient is able to focus at distance and near without glasses or contacts. The ReStor® IOL was designed by combining diffractive and refractive technologies that have been used to improve the image quality in telescopes and microscopes. Diffraction involves spreading the light to multiple focal points. Refraction involves redirecting the light as it passes through the lens in order to focus on the retina. The combination of the two allows you to focus on objects at varying distances. Side effects from this IOL include experiencing possible halos or glare.
In clinical studies, four out of five patients reported not having the need to wear glasses after the procedure. This gives many patients the freedom of reading, driving and doing other tasks without glasses.
Discuss with your doctor if this could be the right treatment for you.
