AcrySof® ReSTOR® Lens Cataract Surgery
For most cataract patients, life without reading glasses or bifocals is something they either experienced before presbyopia or they just dreamed about for most of their lives. But today, the AcrySof® ReSTOR® IOL is turning those dreams into reality with its revolutionary lens technology, which is designed to allow patients to see clearly at all distances without bifocals or reading glasses. The AcrySof® ReSTOR® IOL is now available and delivers a high level of glasses-free vision for cataract patients.
In the clinical study, 80% of patients receiving the AcrySof® ReSTOR® IOL reported that they never wear glasses for any activities. With the AcrySof® ReSTOR® IOL they can read a book, work on the computer, and drive a car – day or night – and play golf or tennis with an increased freedom from glasses. In fact, patients were so pleased with their vision, nearly 94% of patients said they would have the AcrySof® ReSTOR® IOL implanted again, if given the choice.
The ReSTOR® Procedure:
Cataract surgery is performed on an outpatient basis, and usually requires just a few hours of your time from start to finish. Your eye will be treated with anesthetic prior to the procedure so you’ll feel little, if any, discomfort. First, a tiny incision will be made in the eye allowing your surgeon to use a small instrument (about the size of a pen tip) to break up or wash away the cloudy cataract. Once the cataract is removed, the AcrySof® ReSTOR® IOL will be inserted through the same tiny incision and set into its permanent position.
After the Procedure:
After the procedure you’ll rest for a short while before you go home. Your doctor will typically examine your eye within 24 hours. You’ll need to use prescription eye drops to guard against infection and help your eye heal. For a few days, you may need to wear a protective shield, especially at night to prevent you from rubbing your eye. Everyone heals somewhat differently, but most patients see well enough to return to most of their routine activities the day after surgery. Once both eyes have been treated, you will fully appreciate the AcrySof® ReSTOR® IOL and realize that your cataract was one thing you could definitely live without.
AcrySof® ReSTOR® Frequently Asked Questions
:: What can I expect after the procedure?
Similar to other lens implant procedures, you can expect your vision to be good the day following surgery.
:: How soon after the procedure will I be able to see at varying distances?
For most patients, near vision is good the next day and improves over the following week. Results are best when both eyes have ReSTOR® lenses implanted.
:: How many patients are 100% glasses free after having this procedure?
The results are very good. After having ReSTOR® lenses implanted, 80% of patients say they never wear glasses. Nearly 94% were so satisfied that they would have the procedure again.
:: Who is a candidate for this procedure?
Anyone who has a normal eye exam and is dependent on reading glasses or bifocals may be a candidate. Although ReSTOR® lenses are a breakthrough technology initially approved for cataract patients with or without presbyopia, it is not necessary to need cataract surgery to qualify for the ReSTOR® lens, just a desire to restore eyesight at a range of distances without corrective eyewear.
There are no known contraindications. However, based on the FDA clinical trials, Alcon, the lens manufacturer, has indicated the following types of patients should not have the AcrySof® ReSTOR® Apodized Diffractive IOL:
- Patients who are hypercritical with unrealistic expectations.
- Patients with excessive complaints about their prescription.
- Patients who drive at night for a living or whose occupation or hobbies depend on good night vision.
- Patients who are amateur or commercial airline pilots.
- Patients who have lifelong complaints about glare.
- Patients who are happy wearing glasses.
- Patients who want guarantees on surgical outcomes.
March 23, 2005. It has been approved for use in Europe since April 4, 2003.
:: How many people in the US have had the ReSTOR® lens procedure?
During clinical trials, 566 people received the ReSTOR® lens.
:: What are the risks/contraindications of this procedure?
The greatest risk is infection, which is very rare. Patients receive several days of preoperative antibiotics to minimize this risk. Statistically, the amount of risk for the ReSTOR® lens implant procedure is not much different from LASIK Surgery. Lens implant surgery is one of the most commonly performed surgeries in the United States.
:: Is this a reversible procedure?
Once the natural lens is removed, it cannot be replaced. However, if one is over 40 and dependent on reading glasses or bifocals, the lens is already not normal. It has lost its accommodation ability. If the patient desires, the ReSTOR® lens implant can be removed and replaced. In the United States arm of the FDA Clinical Trials for ReSTOR®, no patient requested removal of the lens because the benefit of a full range of vision outweighed their complaints of visual disturbances. The only medical indication for lens replacement is if the lens power needs to be changed to help distance vision.
:: Is the ReSTOR® lens more effective than other IOLs?
The ReSTOR® lens is like two lenses in one. One refractive lens is for distance, and the other one, a diffractive lens, is for near. ReSTOR® is not dependent on the movement of the lens but has a unique Apodized Diffractive optic that is new to IOL design. The optical design of the lens distributes light between near vision and distant vision to accommodate vision at a range of distances.
