Once your cataract is removed, a new lens implant is inserted to replace it. Your lens implant choice will determine your vision after cataract surgery. There are many different types of intraocular lens implants (IOLs) to choose from. In addition, many people with clear lenses are opting for lens exchange to improve near and distance vision. Lens replacement is the most frequently performed surgery in the U.S. and one of the safest. You have three categories of lens implant to choose from.
Correcting distance vision with a monofocal IOL
A monofocal IOL is designed to provide clear distance vision. This means, after cataract surgery, you will be able to see objects far away. However, you will need glasses for reading and any type of close detailed work. Monofocal IOLs have been the standard implant used for decades to help patients see after a cataract is removed. Millions of monofocal IOLs have been successfully implanted providing cataract patients with clear distance vision.
Correcting distance vision and astigmatism
Astigmatism Management is a vital new area of cataract surgery. Astigmatism is a common condition where your eye is out-of-round, shaped more like a football than a basketball. Your vision is potentially affected by two types of astigmatism — corneal and lenticular — and we can correct both with new astigmatism management tools. Today’s cataract patient demands excellent vision after surgery, and wants their astigmatism and refractive error corrected at the same time. There are two ways we correct pre-existing astigmatism during cataract surgery. The most advanced method uses a new type of lens implant, called a Toric lens, which incorporates unique optics to compensate for specific deficiencies in your vision. Toric lenses greatly reduce the likelihood of needing a second procedure to correct residual astigmatism. For those patients who suffer from astigmatism so pronounced that they are outside the power range of the Toric lens, we recommend a combination treatment of lens replacement and relaxing incisions that delivers both improved vision and astigmatism correction. Once we fully understand your level of astigmatism, and desire for improved distance vision and/or near vision, we will recommend the appropriate lens implant option for you.

Correcting vision with multifocal or accommodating IOLs
Previous lens replacement technologies provided only one focal point – distance – leaving people dependent upon reading glasses or bifocals after cataract surgery. Recent advances in accommodative and multifocal technology now make it possible for you to read the words on prescription bottles, magazines, newspapers and computer screens, without magnifying glasses or bifocals, while still clearly seeing objects at a distance. These lenses have the ability to consistently offer improved vision at all ranges — near through distance. With the introduction of three advanced technology lenses — ReSTOR, Crystalens and Tecnis – the vision we can help you maintain as you age is better than ever before in the history of ophthalmology.
The AcrySof® ReSTOR® multifocal lens uses patented technology similar to that used in microscopes and telescopes to improve image quality. Twelve very small, concentric circles work together to focus light for both near and distance vision.
With the ReSTOR, vision delivery is ideal for reading at a comfortable distance, improving mid-range clarity for items like store labels and computer screens, and seeing clearly at distance. Learn More About ReSTOR
The Crystalens® accommodating lens is designed to restore the eye’s accommodative ability, which is gradually reduced as presbyopia progresses. Crystalens has hinges on both sides of the IOL, so it can be moved more easily by the ciliary muscle, allowing the eye to focus more naturally at a greater range of distances than traditional IOLs.

The Tecnis® multifocal IOL uses concentric refractive zones to create multifocal vision. Diffractive rings start very close to the center of the lens and then continue out toward the periphery, with an increasing distance between the rings. This design performs well regardless of pupil size, providing excellent near vision even in the presence of relatively small pupils. The Tecnis implant was designed with an aspheric shape to correct for certain, more complex vision errors, known as higher-order aberrations, which helps improve ability to see contrasting objects, particularly at night.

ReSTOR, Crystalens and Tecnis IOLs have demonstrated effectiveness in improving near, intermediate and distance vision in FDA clinical trials. We believe these lens implants provide excellent vision quality to those weighing their lens choice options. Dr. Zimm will discuss with you which lens will be best-suited for your vision needs at your Lens Evaluation.
