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 after cataract surgery. 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.

Multifocal IOLs such as ReSTOR®, and Tecnis® preserve distance vision and correct presbyopia in cataract surgery patients -- and patients seeking treatment for presbyopia alone -- can enjoy clear sight without relying on glasses.
Through recent advancements in lens technology, an IOL is now available that can provide the patient with a greater range of vision while reducing the need for glasses and contacts. The ReSTOR intraocular lens from Alcon Company provides a full range of functional vision for patients that desire a significant decrease in their dependence on glasses or contacts
Crystalens™ is a new cataract replacement lens (IOL) that works naturally with muscles in the eye to retain the eye's ability to "accommodate" - shift focus between nearby and distant objects - after cataract surgery. It is the first FDA-approved accommodating lens. With other IOLs, patients lose this ability and require corrective measures such as glasses or contact lenses. Crystalens can treat both cataracts and presbyopia, exactly like multifocal lenses but in different way.
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 5 diopters of astigmatism.
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.
