Multifocal & TORIC IOL |
| Toric Intraocular Lenses |
| When the natural crystalline lense of the eye is removed during cataract surgery, it can be replaced with a toric intracular lens (IOL) to correct astigmatism. Toric intraocular lenses are not multifocal lenses, but they can provide significantly improved vision for people suffering from moderate to high astigmatism. |
Intraocular Lenses – Multifocal and Monofocal Lens Implant |
| Intraocular lenses - also called IOLs - come in two varieties: monofocal and multifocal intraocular lenses. IOLs are implantable lenses that replace the lens of the eye when it is removed during cataract surgery. Originally, IOLs were monofocal, or corrective of vision at one distance only, whether near, intermediate, or far. Since they correct vision at just one distance, glasses are still needed, especially if the patient suffers from presbyopia (or age-related farsightedness). Newer, multifocal intraocular lenses will correct vision at multiple ranges, without the use of glasses or regular contact lenses. |
ReSTOR® |
| AcrySof® ReSTOR® multifocal intraocular lenses are uniquely designed to improve vision at all distances, giving cataract patients the opportunity to experience life without glasses. ReSTOR® is modeled after microscope and telescope technology and focuses at both near and far distances, decreasing your dependency on glasses. Learn more about the AcrySof® ReSTOR® intraocular lens.

Crystalens® |
| Crystalens® is the first intraocular lens for cataracts that also provides accommodation, the ability to adjust focus between near, far, and midrange vision. Crystalens® is designed to mimic the eye’s natural process of accommodation. Other monofocal IOLs are fixed and stationary within the eye. Learn more about Crystalens® IOLs. |
TECNIS™ |
| TECNIS™ intraocular lenses minimize glare and have been shown to allow significantly greater detail and contrast than traditional IOLs. TECNIS™ lenses have shown particular effectiveness in patients with reduced contrast sensitivity in low-light situations. Learn more about the TECNIS™ IOL.

Types of IOLs |
If you are considering cataract surgery to replace the lens in your eye, you should discuss with your doctor which of the different types of IOL may work best for you. There are two main types of IOL to consider: monofocal and multifocal intraocular lenses. |
A multifocal lens implant is designed for the correction of both near and far vision. Your brain must learn to select the visual information it needs to form an image of either near or distant objects, so multifocal lenses may require a period of adjustment. A person may adjust better to multifocal intraocular lenses if they are placed in both eyes. |
The IOL Procedure |
| The IOL procedure is performed on an outpatient basis, usually requiring just a few hours to complete. The eye(s) is treated with anesthetic to limit any discomfort. A tiny incision is made at the edge of the eye and the cataract is removed. The monofocal or multifocal lens implant is then inserted through the same tiny incision. |
Am I a Candidate? |
| Generally, to be a candidate for monofocal or multifocal intraocular lenses, a patient should have healthy eyes and a stable refraction. Patients must demonstrate at least six months of stable refraction prior to surgery. If you have noticed a blurring of your vision or other symptoms of cataracts, or if presbyopia has made reading small print a frustrating ordeal, you may be a good candidate for vision correction with intraocular lenses. |
Risks of Intraocular Lenses |
| Although complications are rare, there are certain risks associated with intraocular lens surgery. Your ophthalmologist will perform a thorough examination of your eyes and will review your medical history to determine any factor or factors that may increase your susceptibility to IOL risks. Statistics show complications occur in less than 5 percent of cases. |
