WHAT IS THE Tecnis MULTIFOCAL LENS?
The Tecnis Multifocal Intraocular Lens (IOL) is the most recent innovation in lens implant technology. The Tecnis Multifocal 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 Austin cataract surgery patient who is 45 or older and dependent on glasses and/or contacts to see near, far and in-between.
HOW DOES IT WORK?
The Tecnis Multifocal lens replaces the natural lens and is implanted into the eye during cataract surgery. It has a patented optic design that works like a bifocal lens inside the eye. For long-distance vision, the Tecnis multifocal 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 Tecnis multifocal lens creates a clear, sharply focused near image and a second highly defocused far away image that is typically not perceived. This unique multifocal 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 Tecnis Multifocal Lens? The lens has the ability to consistently offer patients improved vision at a range of distances, from close-up to middle and far. Because the Tecnis multifocal lens 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 Tecnis Multifocal lens is similar to two lenses in one. One, a refractive lens is for distance, the other, a lens for near vision. This gives the Tecnis multifocal IOL more consistent results and more satisfied patients who can enjoy activities like reading, sewing, seeing your smartphone or looking at the fine print on documents, all without the hassle of reading glasses, bifocals, progressive lenses or contact lenses.
WHEN IS IT USED?
The Tecnis multifocal 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 Tecnis multifocal 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 Tecnis multifocal lens, just a desire to reduce or eliminate your dependence on glasses.
WHAT WILL THE Tecnis MULTIFOCAL LENS ACCOMPLISH?
The Tecnis multifocal 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. Patients with the Tecnis multifocal lens in both eyes have a 90% chance of not needing glasses for any activity.
WHEN SHOULD IT NOT BE USED?
There are no known contraindications. However, based on past experience the following types of patients possibly should not have the Tecnis multifocal lens implant:
- 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 Tecnis multifocal 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 Tecnis multifocal IOL revealed that maximum visual performance is achieved when the 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 the Tecnis multifocal IOL greatly reduces dependence on glasses or bifocals:
- Over 94% of patients said they would choose the Tecnis multifocal lens again.
- Nearly 9 out of 10 patients enjoy freedom from glasses after receiving the Tecnis multifocal lens.
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 for long periods of computer work.
After surgery with the Tecnis multifocal 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 basic 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 Tecnis MULTIFOCAL 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. Austin Eye is proud to offer both traditional cataract surgery and bladeless cataract surgery in Austin, using the LenSx laser. During your eye exam, we will determine if there are pre-existing conditions that would make lens replacement surgery with the Tecnis multifocal lens not advisable.
People who have had prior corneal refractive surgery (i.e. LASIK, iLASIK, or PRK) may be acceptable candidates for Tecnis multifocal IOL 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 Tecnis multifocal implant. Also individuals with more extreme levels of nearsightedness or farsightedness may be better candidates for lens replacement surgery with the Tecnis multifocal 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 Austin Tecnis IOL patients, near vision is good the next day, and improves over the following week. Results are best when both eyes have Tecnis multifocal lenses implanted.

WHAT ARE THE RISKS OF LENS REPLACEMENT SURGERY WITH THE Tecnis MULTIFOCAL 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 U.S. today with 3 million procedures performed annually.
Additionally, individuals who are planning to receive the Tecnis multifocal lens may need additional surgery to “fine-tune” their vision. These procedures may be done before, during or after the lens is inserted. In rare instances a monofocal lens implant may be used during surgery rather than the Tecnis multifocal.
IS THE Tecnis MULTIFOCAL LENS MORE EFFECTIVE THAN OTHER LENS IMPLANTS?
The Tecnis multifocal lens is like two lenses in one. One refractive lens is for distance, and the other one for near. Tecnis multifocal is not dependent on the movement of the lens but has a unique 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 Tecnis multifocal 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/or 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 advantage of the Tecnis multifocal lens over the ReSTOR lens: 1) the Tecnis lens implant design gives better reading vision in low light environments than the ReSTOR lens.
WHAT IS THE DIFFERENCE BETWEEN THE Tecnis MULTIFOCAL LENS AND A BASIC INTRAOCULAR LENS (IOL)?
The Tecnis multifocal 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, basic (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 AM I STILL A CANDIDATE FOR THE Tecnis MULTIFOCAL LENS?
Yes. People who have had prior corneal surgery are acceptable candidates for the Tecnis multifocal lens as long as their eye is in good health. Consult with your ophthalmologist to understand the issues associated with use of the Tecnis multifocal lens after prior laser vision correction.
