 The probe breaks up, or emulsifies the cloudy lens into tiny pieces and then suctions them out of the eye. Once the cloudy lens has been removed, a new artificial lens is implanted into the eye. This lens is known as an intraocular lens (IOL), and can often be inserted through the same incision that the old lens was removed from.There are several different IOLs available to help each patient achieve the best possible results from his/her cataract surgery. Multifocal IOLs allow for full vision correction at near, intermediate and far distances, completely eliminating the need for eyeglasses or contact lenses in most patients. Some IOLs can also correct astigmatism. These choices were not always available for cataract patients. In the past, cataract surgery only involved monofocal lenses, which could only focus on objects near or far, but could not adjust to accommodate varying distances. These patients still had to rely on glasses or contact lenses after surgery in order to see clearly at all distances.  This was especially problematic in older patients suffering from presbyopia, a loss of flexibility in the eye’s lens that causes nearby objects to look blurry.

Patients can return home the very same day. Cataract surgery is done as an outpatient procedure in an operating room, so you don't have to stay in the hospital. The actual surgery usually lasts less than an hour. It is safe and in many ways desirable to be awake with some level of sedation during the surgery, but will need someone to drive them home. A sedative is given and numbing drops are placed on the eyes.

 

Surgical Risk and Complications

Although cataract surgery is considered safe, there are certain risks associated with any surgery. Some of these risks may include pain, infection, swelling and bleeding. However, most patients undergo this procedure without any complications.  Complications after cataract surgery are uncommon, and most can be treated successfully.Cataract surgery risks include:

•             Inflammation

•             Infection

•             Bleeding

•             Swelling

•             Retinal detachment

•             Glaucoma

•             Secondary cataract

•             Loss of vision

Your risk of complications is greater if you have another eye disease or a serious medical condition affecting any part of your body. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.

 Multifocal Intraocular Lens Implant

 

The ReSTOR® lens improves upon the ordinary IOL by using anodized diffractive technology to provide a full range of focusing distances from near to far. A series of 12 gradual "step heights" of 0.2-1.3 microns each (thinner than a human hair and smaller than a red blood cell) in the center of the IOL create seamless focusing ability, while the peripheral refractive region helps to enhance distance vision. Apodization also allows the lens to work with the pupil to distribute light evenly in the eye in different lighting conditions and activity levels. Alcon® reports that up to 80 percent of patients who use the ReSTOR lens don't need glasses after surgery.

 
Toric (Astigmatic) Intraocular Lens Implant

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 three diopters of astigmatism. Cataract 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.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.
