What is an Intraocular Lens?
During cataract surgery, the cloudy lens of the eye is removed and replaced with a clear intraocular lens (IOL). The eye’s lens focuses light onto the retina, and when it becomes clouded by cataracts the result is blurred vision. By replacing the lens affected by cataracts with a synthetic IOL, clear vision is restored.1
Standard IOLs vs Advanced IOLs
Most frequently, a standard IOL is used during cataract surgery to replace a cloudy lens. Standard IOLs can reverse the effects of cataracts and may also provide clear distance vision, and they are covered by insurance for cataract treatment. However, patients who undergo cataract surgery and have astigmatism or presbyopia may still require glasses or contacts after their surgery.
At Valley Eye Institute, we also offer advanced IOLs to our patients undergoing cataract surgery. These lenses are specially designed to help correct refractive errors like astigmatism and presbyopia, which means that patients may no longer require glasses or contacts after cataract surgery with an advanced IOL.
Types of Advanced IOLs
Toric IOLs for Astigmatism
Toric IOLs are especially designed for patients with astigmatism, which is an irregular curvature of the cornea that causes vision to be distorted or blurred. We offer a range of toric IOLs, with options available to correct astigmatism and vision at one distance or multiple distances.
Presbyopia is age-related loss of near-focusing, and is a common part of the eye’s aging process that begins to affect people at around age 40. Presbyopia makes it difficult to focus on objects up close, so people with this refractive error often require bifocals or reading glasses for certain tasks.2 We offer a number of types of presbyopia-correcting IOLs that can help patients correct near, intermediate and distance vision, giving patients the best chance at freedom from corrective eyewear after surgery.
The presbyopia-correcting IOLs we offer include:
- Multifocal IOLs including the Acrysof® ReSTOR® and the Tecnis®
- Extended Depth of Focus (EDOF) IOLs including the Acrysof® Vivity® lens
- Trifocal IOL using the Acrysof® PanOptix® lens
