Chicago Multifocal IOL Specialist Stuart Sondheimer, MD
What are IntraocuLar Lenses?
An intraocular lens, also known as an IOL, is an artificial replacement lens. These replacement lenses are implanted after the natural lens of the eye has been surgically removed during cataract surgery. After IOL placement, patients can often see without the need for glasses or contacts and have clear vision.
Multifocal IOL Options
In the past, monofocal intraocular lenses were the only option patients had. Now, patients can have multifocal IOLs placed at the conclusion of cataract surgery to correct vision at near, intermediate and far distances. As a result, multifocal lenses can completely eliminate the need for glasses or contact lenses for most patients. Multifocal intraocular lenses appeal to patients that prefer not to wear glasses or contact lenses. Dr. Sondheimer offers the following multifocal intraocular lenses:
- Alcon PanOptix
- AMO Symfony IOL
- Tecnis Multifocal
- Alcon ReSTOR® Multifocal IOL
Reasons For IntraocuLar Lenses
An Intraocular lens allows patients a quality range of vision. A cataract occurs because the eye’s natural lens becomes cloudy or opaque. As the lens becomes more cloudy over time, it prevents light from being focused on the retina, and thus, vision diminishes. Cataracts grow at different rates, some more quickly than others, and there is no cure but to have the cloudy lens removed.
Once the eye’s natural lens has been removed, a new, man-made intraocular lens (IOL) is used to replace it. There are many IOLs that will usually serve patients well for distance vision, but patients must still wear glasses for reading or for good vision at near.
WHAT IS THE RESTOR® INTRAOCULAR LENS (IOL)?
Chicago cataracts specialist, Dr. Stuart Sondheimer, is among the first surgeons in the United States to be trained and certified to implant the new Alcon AcrySof® ReSTOR® intraocular lens (IOL). According to Dr. Sondheimer, I believe this new lens is an innovative technology that can help many cataract patients see remarkably well without glasses or contacts of any kind following surgery. This is an important new advancement, and I want to be able to deliver the newest technology to my patients who want a lifestyle free from corrective eyewear, he explained.
What makes the restor iol different?
According to Alcon, Inc., the lens was approved in the United States by the Food & Drug Administration (FDA) in March 2005. It is the first and only lens to use a particular diffractive technology that achieves a range of vision for patients thus enabling it to function much like the eye’s natural lens. ReSTOR® does not rely on the eye’s ciliary muscle to change focus between near, intermediate and distance, but instead relys on the diffractive properties of the lens itself. Weakening of the ciliary muscle is the root cause of presbyopia which results in the need for reading glasses or bifocals.
That is the significance of this lens, explained Dr. Sondheimer. It potentially offers a great range of freedom from corrective eyewear that many patients are choosing. In fact, with this new lens, it is possible that people who have worn glasses for 10, 20, 30, or even 40 or more years, may enjoy good vision for the rest of their lives without corrective lenses.
According to the manufacturer, clinical trials were conducted in the United States and Europe to establish safety and effectiveness of the new lens. More than 11,000 ReSTOR® IOLs have been implanted by more than 900 surgeons in Europe and other countries. Further, it is estimated that more than 21 million implants used worldwide since the lens introduction in the early 1990s.
What Is a Symfony IOL?
Chicago eye surgeon Dr. Sondheimer is committed to long-term patient satisfaction. His training and continued interest in treatment advances allow patients to consider multiple options for bringing clear vision back into their lives. We are pleased to offer Symfony IOLs to our comprehensive menu or services. Traditional intraocular lens solutions have focused on providing clear vision after cataract removal surgery. More recently, IOLs have become an innovative type of medical device for correcting certain refractive errors, such as presbyopia. Historically, this common vision problem has been treated with some type of multifocal or trifocal lens. These lenses work by fractionating light into multiple points of focus.
In addition to traditional IOLs, manufacturers have also developed accommodating lenses to correct presbyopia. These lenses work through flexibility, changing shape as the muscle of the eye moves. An accommodating IOL may provide clearer vision at a distinct distance. The Tecnis Symfony IOL has been developed to offer continuous, full-range vision with a lower incidence of distortions such as halos or glare while correcting presbyopia.
What Is a Symfony Toric IOL?
The Tecnis Symfony Toric lens has been developed to correct astigmatism by featuring advanced materials and optics such as:
- A wide range of optical powers (diopters) to accommodate more patients
- Hydrophobic acrylic lenses are less likely to result in glare or halos
- Correction of spherical aberration results in sharper vision
- Tri-Fix 3-point fixation improves the stability of vision at various distances

Candidates for a Symfony IOL
Many adults who are good candidates for cataract removal are also good candidates for a Symfony IOL. Tecnis Symfony IOLs may also be used to correct presbyopia or astigmatism during lens exchange treatment. Dr. Sondheimer can help you determine which type of IOL is best suited to your needs during a thorough eye exam and consultation.
Benefits of Symfony IOLs
Lens replacement offers several general benefits. Symfony IOLs provide advantages including:
- Fewer issues with glare, halos, and loss of contrast. Vision remains sharper and clearer during the daytime and nighttime.
- Continuous vision adaptation reduces the need for eyeglasses or contacts for up close or distance usage.
What is the Tecnis Multifocal IOL?
Dr. Sondheimer is a leading Chicago eye surgeon who is adept at performing a range of vision correction procedures utilizing the latest technologies. His commitment to providing his cataract surgery patients with the most optimal vision correction results has motivated him to offer high-quality intraocular lens implants (IOLs) to serve the unique vision needs of each individual who seeks his services. Among several other advanced intraocular lens implants, Dr. Sondheimer offers the Tecnis Multifocal premium lens implant.
The Tecnis IOL was developed by Advanced Medical Optics, Inc. (AMO) using wavefront analysis of human corneas. It was specifically engineered to cater to patients who wish to obtain improved vision acuity at multiple distances following cataract surgery. Tecnis first gained FDA-approval in early 2009 as a new IOL that gives cataract surgery patients, with or without presbyopia, superior near and reading vision. In addition, Tecnis is also known to improve intermediate and distance vision, often without the need for eyeglasses or contact lenses.
Intraocular Lens Placement
Lens exchange may be performed in conjunction with cataract removal or as the primary procedure. Treatment is conducted on an outpatient basis. Before commencing with the minor surgical technique, we administer a local anesthetic into the eye to numb the ocular surface. These medicated eye drops work almost instantly and keep you comfortable throughout your procedure, which may be completed in an hour or less. In most cases, the tiny incision made to replace the natural lens does not require stitches. Once the new lens is in place, a bandage may be placed over the eye.
Symfony IOL Placement Recovery
Vision improves almost immediately after lens exchange surgery. Initially, the eye may be covered with a bandage to prevent irritation from debris or photosensitivity. It may be possible to remove the bandage after 24 hours. We will provide detailed post-operative instructions before your procedure.
Lens exchange surgery may result in temporary blurriness and minor discomfort. Eye drops may be prescribed to prevent dryness and infection. A post-operative eye exam may occur a few days after surgery and then again at one- to two-weeks and four-weeks post-op. As healing continues over several weeks, it is necessary to avoid rubbing or pressing on the eye. Usually, the eye is completely healed within eight weeks.
Results of IOL Placement
In one US study, results from the placement of an IOL demonstrated outstanding results. These included:
- 20/20 mean uncorrected binocular visual acuity for distance.
- 20/20 mean uncorrected binocular visual acuity for intermediate vision.
- 20/25 mean uncorrected binocular near visual acuity.
These results mean that the majority of patients studied did not need a new prescription for eyeglasses after their lens replacement.
Risks of IOL Placement
Ongoing clinical use has proven that refractive lens exchange, like cataract surgery, is safe and effective. The risk of severe complications is very low. Most complications that may occur after eye surgery can be easily treated. The most common risks of this procedure include:
- Increased intraocular pressure
- Dislocation of the implanted IOL (shifting)
- Bleeding in the eye
- Ptosis (drooping eyelid)
