Cataract Surgery > Types of Lens Implants

Intraocular Lenses

Intraocular lenses (IOLs) are medical devices that are implanted inside the eye to replace the eye’s natural lens when it is removed during cataract surgery.

These days there a wide variety of premium IOL’s to choose from. The best intraocular lens for you depends on many factors including your lifestyle and your specific visual needs.

Toric Lens

When the natural cataract has been removed during surgery, a Toric intraocular lens can be inserted. Toric IOLs are premium intraocular lenses that correct astigmatism as well as nearsightedness or farsightedness. Like toric soft contact lenses, toric IOLs can correct astigmatism because they have different powers in different meridians of the lens. They also have alignment markings on the peripheral part of the lens that enable me as the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction.
Just prior to cataract surgery, I usually place temporary markings on the front of the eye (the cornea) that identify the location of the most curved meridian of the front of the eye. Then, when the toric IOL is implanted during the cataract procedure, I rotate the IOL so the markings on the IOL are aligned with the markings on the cornea to insure proper astigmatism correction.
Please don’t hesitate to contact me and arrange a consultation if you would like to discuss Toric lens surgery.

Multifocal Lens

Multifocal IOLs are another category of intraocular lenses that can decrease your need for reading glasses or glasses for computer work after cataract surgery.

Just like multifocal contact lenses, these premium IOLs contain added magnification in different parts of the lens to expand your range of vision so you can see objects clearly at all distances without glasses or contact lenses.
Some studies have shown multifocal IOLs tend to provide better near vision than accommodating IOLs, but they also are more likely to cause glare or mildly blurred distance vision as a tradeoff.
In my professional experience a detailed consultation to help you decide if you are a good candidate for multifocal IOLs. Popular FDA-approved multifocal IOLs include: Tecnis Multifocal IOL (Abbott Medical Optics) and AcrySof IQ ReSTOR (Alcon).
