WHAT IS THE ReSTOR LENS?
The ReSTOR Lens is the most recent innovation in lens implant technology. The ReSTOR lens is implanted in the eye as a lens replacement at the time of cataract surgery or refractive lens exchange. The best candidate is the individual who is 45 or older and dependent on glasses and/or contacts to see near, far and in-between.
As top vision correction providers, the team of experienced Austin eye care professionals at Austin Eye use advanced techniques and technologies to provide Austin cataract patients with restored vision. As evidence of their dedication to provide the best vision correction solutions, they offer the ReSTOR lens to their patients from Austin and the surrounding area.
HOW DOES IT WORK?
The AcrySof ReSTOR IOL replaces the natural lens and is implanted into the eye in a procedure identical to cataract surgery. It has a patented apodized diffractive optic design that works like a bifocal lens inside the eye. For long-distance vision, the ReSTOR lens creates a clear image of the far away object while at the same time a second, highly defocused image is created for near vision that is typically not perceived. For near vision, the ReSTOR lens creates a clear, sharply focused near image and a second highly defocused far away image that is typically not perceived. This apodized diffractive optic design gives it the ability to provide clear vision near, far and in-between without mechanical movement of the lens.
What is unique about ReSTOR? The lens has the ability to consistently offer patients improved vision at a range of distances, from close-up to middle and far. Because ReSTOR doesn’t work with the muscles of the eye, it is not dependent on a mechanical process or the movement of the lens to give clear vision.
The ReSTOR lens is similar to two lenses in one. One, a refractive lens is for distance, the other, an apodized diffractive lens is for near vision. This gives ReSTOR more consistent results and more satisfied patients who can enjoy activities like reading, sewing, reading their smartphone, or looking at the fine print, all without the hassle of reading glasses, bifocals, progressive lenses or contact lenses.
WHEN IS IT USED?
The ReSTOR IOL is used in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased independence from glasses following cataract or lens replacement surgery.
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.
WHAT WILL THE ReSTOR LENS ACCOMPLISH?
The AcrySof ReSTOR IOL has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses in patients who have undergone cataract surgery.
WHEN SHOULD IT NOT BE USED?
There are no known contraindications. However, based on the FDA clinical trials, Alcon, the lens manufacturer, has indicated the following types of patients possibly should not have the AcrySof ReSTOR Apodized Diffractive IOL:
- Individuals that are hypercritical with unrealistic expectations
- Individuals with excessive complaints about their prescription
- Individuals who drive at night for a living or whose occupation or hobbies depend on good night vision
- Individuals who are amateur or commercial airline pilots
- Individuals who have life-long complaints about glare
- Individuals who are happy wearing glasses
- Individuals who want guarantees on surgical outcomes
- Individuals who have had previous Radial Keratotomy (RK) surgery
- Individuals with pre-existing retina conditions such as macular degeneration
The FDA-approved ReSTOR lens is a breakthrough in intraocular lens technology for most people with cataracts, with or without presbyopia, that may restore more youthful vision. Results from a controlled clinical study of the AcrySof ReSTOR IOL revealed that maximum visual performance is achieved when the ReSTOR lens is implanted in both eyes. Benefits are apparent with individuals in whom the lens is used in only one eye as well.
Clinical data demonstrates that AcrySof ReSTOR IOL greatly reduces dependence on glasses or bifocals:
- 80% of patients reported that after lens implant surgery with ReSTOR lenses, they never needed glasses or contact lenses to see clearly at all distances near, far and in-between.
- 99% of patients could see well enough to drive a car without glasses or contacts.
- 97% of patients could read the newspaper without reading glasses or bifocals.
- 90% of patients could shave or put on makeup without glasses or contacts.
- 80% of patients NEVER wear glasses for any activities.
Everyone’s focusing ability is different. Most people will be able to see clearly in the distance, have very good reading vision and functional intermediate vision without glasses, but some people may be more comfortable with additional correction, particularly at night or in dim light or for long periods of computer work.
After placement of the ReSTOR lens, it may be necessary for some people to wear glasses for distance, intermediate and/or near vision to obtain optimal visual acuity. The difference from standard lenses is that most people will not be as dependent on these supplemental vision aids to function normally.
WHO IS A GOOD CANDIDATE FOR THE ReSTOR IOL?
Virtually everyone who has cataracts and/or presbyopia (loss of ability to refocus vision, noticed after age 45) and is in good general health may be candidate for refractive lens exchange and/or cataract surgery with the ReSTOR, Tecnis multifocal or the Crystalens. During your eye exam, we will determine if there are pre-existing conditions that would make lens replacement surgery with the ReSTOR lens not advisable.
People who have had prior corneal refractive surgery (i.e. LASIK, iLASIK, or PRK) may be acceptable candidates for ReSTOR implantation as long as their eyes are in good health. After a thorough examination, we will be able to better advise you if you qualify for the ReSTOR implant. Also individuals with more extreme levels of nearsightedness or farsightedness may be better candidates for lens replacement surgery with the Crystalens and/or the ReSTOR lens than laser vision correction.
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. There is minimal discomfort after surgery that usually resolves within hours. Most individuals can return to a normal work schedule/routine the day after 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 THE ReSTOR LENS IMPLANT?
The results are very good. After having ReSTOR lenses implanted to both eyes, 80% of patients say they never wear glasses.
WHEN DID THE ReSTOR RECEIVE FDA APPROVAL?
March 23, 2005. It has been approved for use in Europe since April 4, 2003.
WHAT ARE THE RISKS OF LENS REPLACEMENT SURGERY WITH THE ReSTOR LENS IMPLANT?
Lens replacement surgery is identical to cataract surgery and results in safe and successful outcomes in approximately 98% of eyes treated. Like any surgical procedure, there are risks. During your visit with Dr. Mitchel Wong, Dr. Shannon Wong or Dr. John Odette, the risks, benefits and surgical alternatives will be discussed with you. Fortunately, cataract surgery is one of the most common and safest surgical procedures performed in the US today with 3 million procedures performed annually.
Additionally, individuals who are planning to receive the ReSTOR lens may need additional surgery to “fine-tune” their vision. These procedures may be done before, during or after the ReSTOR lens is inserted. In rare instances a monofocal lens implant may be used during surgery rather than the ReSTOR.
IS THE ReSTOR LENS MORE EFFECTIVE THAN OTHER LENS IMPLANTS?
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. The ReSTOR lens does not rely on movement of the lens implant inside the eye to produce clear near and far vision.
Basic monofocal (fixed-focus) lens implants provide excellent vision after cataract surgery. With a basic lens implant, most individuals will need bifocal glasses and/or contacts to have clear vision near and far. With the Tecnis multifocal lens, ReSTOR and/or Crystalens, you have the opportunity to see near and far seamlessly without glasses and have more youthful vision. The Tecnis multifocal, ReSTOR and the Crystalens implants work very well in properly selected individuals. Still each lens implant has its relative strengths and weaknesses. During your evaluation, Dr. Mitchel Wong, Dr. Shannon Wong or Dr. John Odette will determine which lens is best suited to your visual needs.
The advantages of the ReSTOR lens over the Crystalens: 1) in some individuals, the ability to see very fine print up-close will exceed the near vision of the Crystalens, 2) FDA studies show that 80% of patients who have ReSTOR lenses in both eyes “never” wear glasses for any tasks on a daily basis.
The disadvantages of the ReSTOR lens in comparison with the Crystalens: 1) intermediate (mid-distance) or computer vision distance vision with the Crystalens has been proven to be better with the Crystalens than the ReSTOR, 2) there is a 5% chance of severe nighttime glare and haloes with the ReSTOR that may make night driving difficult…..night vision problems with the Crystalens are much less than the ReSTOR lens.
In some individuals, the optimal combination will be a Crystalens in the one eye and a ReSTOR lens in the other eye.
WHAT IS THE DIFFERENCE BETWEEN THE RESTOR LENS AND A STANDARD INTRAOCULAR LENS (IOL)?
The ReSTOR lens allows for continuous vision up close, far away and at all distances in between, in most cases with patients experiencing the same vision they had when they were younger, without the inconvenience of corrective lenses.
In contrast, standard (single vision, fixed focus) lens implants provide vision at a fixed distance and do not have the ability to provide a full range of near, intermediate and far vision. Most people with single vision implants must wear glasses for near vision and may need to wear glasses for intermediate/arm’s length vision as well.
IF I’VE HAD LASIK OR iLASIK CAN I STILL BE A CANDIDATE FOR CRYSTALENS, ReSTOR OR TECNIS MULTIFOCAL LENS?
Yes. People who have had prior corneal surgery are acceptable candidates for the ReSTOR lens as long as their eye is in good health. Consult with your ophthalmologist to understand the issues associated with use of the ReSTOR lens after prior laser vision correction.
