During cataract surgery, artificial lenses are implanted in the eye to replace the cloudy natural lenses. These artificial lenses, known as intraocular lenses (IOLs), were once only able to correct distance vision, leaving patients dependent on eyeglasses or contact lenses for near vision. Many cataract patients, in addition to suffering from either nearsightedness or farsightedness, also suffer from presbyopia, natural changes to the eyes that occur as we age.
Before premium lenses, patients were unable to see clearly at both near and far distances without the use of eyeglasses or contact lenses. Early lens implants were monofocal, meaning that they had only one focal point and could not adjust to varying distances.
New advances in technology have allowed for the development of multifocal IOLs, which let patients see clearly at all distances, and can even correct astigmatism as well. Premium lens implants are ideal for cataract patients who are also suffering from presbyopia and want a replacement lens that provides a full range of clear vision.
There are several different types of premium lens implants available for cataract patients. Your doctor will work with you to decide which lens is best for your individual eyes to help you enjoy long-lasting, clear vision at near, intermediate and far distances.

The Crystalens HD is an accommodating intraocular lens that provides continuous vision for distances near, far and everything in between. This lens is the most advanced intraocular lens currently available and is ideal for nearly every cataract patient. Patients using this lens can enjoy a full range of vision with only minimal side effects, making it ideal for those struggling from cataracts and presbyopia. This lens mimics the behavior of a normal human lens, with minimized incidences of halos and glares in night vision.
Crystalens is the only FDA-approved accommodating lens and continues to offer patients many advantages, including those offered with the fourth-generation Crystalens HD lens. Cataract surgery with the Crystalens HD lens takes about 20 minutes to perform and provides patients with clear distance vision within a day or two. Intermediate and near vision may be blurry, but will gradually improve over the next two weeks, during which time glasses or contacts may be needed. After the recovery period, many of our patients had good near and intermediate vision, and also had 20/20 or better distance vision.
Using apodization, diffraction and refraction technologies, the ReSTOR lens improves upon ordinary replacement lenses (IOLs) by providing comprehensive focusing capabilities so patients can see clearly in a range of lighting conditions and at all distances -- at noon or midnight, nearby or far away, and many distances in between. Up to 80% of patients who use the ReSTOR; lens don't need to rely on glasses or contact lenses after surgery.
Intraocular lenses are used to correct vision problems during cataract surgery by replacing the old, damaged lens with an artificial lens that clears up and corrects vision, often leaving patients with little to no dependence on glasses. While cataract surgery corrects cloudy lenses, it still leaves patients with astigmatism with distorted vision. Toric IOLs are specially designed to correct astigmatism along with overall vision during cataract surgery, offering complete vision correction.
Before Toric IOLs, people with astigmatism would need to undergo corneal refractive surgery after their lenses were implanted, or would remain dependent on glasses or contact lenses. The advanced Toric IOLs correct the imbalance caused by an irregular cornea shape in patients with astigmatism. There are several different types of FDA approved Toric IOLs, including AcrySof® Toric Lenses, which can correct up to 3 diopters of astigmatism.
The risks of a Toric IOL include poor vision as a result of the lens rotating out of position, although this risk exists with any type of intraocular lens. Toric IOLs are considered safe for most patients with astigmatism and are the only solution to correct vision problems associated with both cataracts and astigmatism. Talk to your doctor to learn more about these lenses and find out if you can enjoy the benefits of Toric IOLs.
Tecnis® Multifocal IOL
Manufactured by Abbott Medical Optics, the Tecnis® Multifocal IOL helps cataract patients achieve clear vision at all distances after surgery, including improved night vision and driving capabilities. Using wavefront technology, the Tecnis lens allows patients to restore the clear, functional vision of their youth. After surgery, up to nine out of ten patients no longer need to wear glasses, results much more successful than those achieved with standard multifocal lenses. It is the only lens FDA-approved to enhance functional vision and night-driving performance.
The advanced Tecnis lens is ideal for patients who have difficulty reading and seeing objects closely, as well as those with poor night vision. This lens is implanted during the same procedure that removes the cloudy lens, and does not require any additional incisions. Patients can enjoy immediate vision improvement in most cases.
