TECNIS® Multifocal Lens Implant
How Vision Changes Over Time
Understanding how your eyes change over time can help bring you one step closer to reclaiming younger vision.
In a healthy eye, the crystalline or natural lens is flexible and pliable. Muscles and fibers within the eye relax and contract, reshaping the lens in order to change focus to near, far or in between, and back again.
In a healthy eye, light enters through the eye’s natural lens and focuses directly onto the retina, yielding a clear image.
Presbyopia is a common age-related condition that is usually first noticed around the ages of 40 and 50. As we age, the once-flexible natural lens becomes firmer and less responsive to the eye’s efforts to change focus. This lack of flexibility reduces the eye’s ability to switch from seeing objects at a distance to seeing objects up close, resulting in the need for reading glasses or bifocals.
Presbyopia occurs when the eye’s lens loses its ability to change focus and direct light precisely onto the retina. This typically results in blurred vision when reading or looking at objects up close.
SIGNS OF PRESBYOPIA
- Loss of ability to read up close
- Difficulty viewing a computer screen
- The need for reading glasses or bifocals
- The need to hold objects farther away to read
Cataracts are a common vision disorder that occurs as a normal part of the aging process. As we age, proteins in the eye slowly begin to cluster together, causing the eye’s natural lens to become clouded and discolored. When this occurs, light rays passing through the eye become scattered and unfocused, resulting in a blurry image.
Cataracts cause light to scatter as it passes through the eye’s natural lens, resulting in blurred, hazy vision.
SIGNS OF CATARACTS
- Difficulty driving, especially at night
- Difficulty seeing at night
- Difficulty viewing a computer screen
- Colors appear dim and faded
- Frequent change in eyeglass prescription
What Are the Solutions?
Cataract surgery is the only treatment that allows you to regain lost vision due to cataracts. When cataracts are removed during your surgery, a surgeon will replace the eye’s natural lens with an intraocular lens (IOL). There are two main types of IOLs: monofocal and multifocal. Monofocal IOLs treat cataracts only. Multifocal IOLs are designed to treat both cataracts and presbyopia.
Make an Informed Decision
Over 18 million people choose to restore their vision and undergo cataract surgery every year.1 Cataract surgery is a straightforward outpatient procedure that removes the clouded natural lens in your eye and replaces it with an artificial lens called an intraocular lens (IOL).
Multifocal IOL vs. Monofocal IOL: What You Need to Know
When selecting a lens, there are two general types of lenses to choose from: multifocal or monofocal lenses. Both will treat your cataract and reestablish your vision, but there are a few key differences.
A multifocal IOL is designed to correct both cataracts and presbyopia. Presbyopia is a common age-related condition. Beginning around the age of 40, the natural lens inside the eye begins to harden and becomes less flexible. This reduces the eye’s ability to switch focus from near to far to in between and back again, resulting in vision loss and, in most cases, the need for reading glasses or bifocals.
A multifocal lens has several different focus regions that are designed to allow you to see clearly up close, far away and in between, and, in most cases, will eliminate your need for glasses. After surgery, you may experience an adjustment period during which you may see rings around lights at night. This is normal, and as the eye adjusts to the lens over time, the visual impression of these rings typically lessens or goes away.
In contrast, a monofocal lens has only one focus region. It allows you to see objects far away, but you will continue to need glasses for reading and other up-close activities.
Monofocal IOL vs. Multifocal IOL
Monofocal IOLs provide good distance vision, but you will continue to need reading glasses to see up close.
Multifocal IOLs are designed to provide you with improved near, intermediate and distance vision and reduce or eliminate your need for reading glasses.
Talk to your doctor about all the benefits of a multifocal IOL and if the TECNIS® Multifocal IOL is the right choice for your lifestyle.
The Superior Results of the TECNIS® Multifocal Lens
The TECNIS® Multifocal Intraocular Lens (IOL) offers patients with age-related vision loss an excellent chance to regain younger vision and become free of glasses.
Designed to provide you with clearer, crisper vision at near, far and everywhere in between, theTECNIS® Multifocal IOL is an implantable lens that improves vision after cataract surgery and corrects presbyopia (the need for reading glasses). If you enjoy activities such as reading, boating, quilting, playing golf, sightseeing or surfing the Internet, the TECNIS® Multifocal IOL may be the right lens for you.
The TECNIS® Multifocal IOL is proven to provide excellent vision at all distances and all lighting conditions1—day and night. In a clinical study, nearly 9 out of 10 patients implanted with theTECNIS® Multifocal IOL did not require reading glasses after their cataract surgery.1 Additionally, an overwhelming majority of people who have received the TECNIS® Multifocal IOL are very satisfied with their vision following the procedure, and 91.7% said they would elect to do it again.1
With the TECNIS® Multifocal IOL, you may comfortably enjoy everyday activities such as reading a menu in a dimly lit restaurant, taking a walk at dusk or even driving at night. Be sure to ask your doctor about whether you are a candidate for the TECNIS® Multifocal IOL.

What to Expect
Immediately after surgery, patients may notice rings around light when driving at night.
As the eye adjusts to the lens over time, the visual impression of rings typically lessens or goes away.
The TECNIS® Multifocal Lens Procedure
Each year, over 18 million cataract surgeries are performed around the world, making it one of the most commonly performed surgical procedures.1
The surgery is generally a 15- to 30-minute outpatient procedure that is performed under local or topical anesthesia. You will be fully awake, but you will be comfortable and feel no pain. Typically, you will be asked to arrive an hour or so prior to your procedure and will be allowed to leave after a period of observation following your procedure.
The TECNIS® Multifocal IOL Procedure
STEP 1: REMOVING THE CATARACT
Your surgeon will make a small incision in your eye, through which your cataract will be removed. To remove your cataract, your doctor will break apart the cataract and extract it, a technique called phacoemulsification. An IOL will then be inserted through the same tiny incision into the lens capsule of your eye.
STEP 2: INSERTING THE IOL
The IOL will be used to replace your cataract-affected natural lens. The lens is made of a material that is flexible, which allows the surgeon to fold and insert it through the small incision described in Step 1.
STEP 3: RENEWING YOUR VISION
Once the IOL is in position, you should begin to notice an immediate improvement in your vision. Because this procedure is performed through an incision that is very small, your eye should be able to heal rapidly with little or no discomfort.
What to Expect After the TECNIS® Multifocal IOL Procedure
1. THE FIRST FEW HOURS AFTER SURGERY
- You will most likely notice an immediate improvement in your vision.
- Most patients are able to leave their doctor’s office and return home soon after surgery.
- Do not rub or touch your eye.
- Be sure to follow your doctor’s instructions when using the postoperative eye drops.
2. THE NEXT FEW DAYS
- Your eye may feel itchy and become sensitive to light. This is normal and should go away after a day or two.
- You will be able to resume simple daily activities, such as reading, watching TV, using the computer and walking.
- Remember to wear the protective eyewear your surgeon provides outside in the sunlight and while sleeping.
- As your brain adapts to the TECNIS® Multifocal IOL, your vision should continue to improve over the next several months.
- Avoid using any soaps, lotion or makeup near your eye.
3. THE NEXT FEW WEEKS
- Continue to avoid strenuous activity and using soaps or lotions near your eye.
- You may use eye makeup with careful application.
- Some itching and redness may still be noticeable but should be decreasing as your vision continues to improve.
- Some patients may notice rings or glare around lights when driving at night. Remember, it takes time for the brain to adjust to seeing with the TECNIS® Multifocal IOL.
4. THE NEXT FEW MONTHS
- Usually, after one month, your eye will be completely healed.
- Most people who experience rings or glare find they are no longer noticeable after about six months.
- With your doctor’s approval, you can get back to your normal daily activities, including active ones such as driving, golfing, jogging, gardening and traveling.
Questions About the TECNIS® Multifocal Lens
Q: Is the TECNIS® Multifocal Lens procedure safe?
A: Every surgical procedure has risks and potential side effects. Your doctor will explain all of these in full detail. However, the lens removal and lens implant technique used in the TECNIS® Multifocal Lens procedure is performed over 18 million times per year worldwide1 and is recognized for its safety and predictability.
Q: How long will it be before I see well?
A: Everyone heals at a different rate, but in most cases, you will notice improved vision almost immediately after your procedure. You may, however, have an adjustment period during which you see some glare or halos around bright lights. In most cases, this goes away over a period of weeks or months.
Q: Will I be totally free from glasses?
A: Many people with the TECNIS® Multifocal Lens experience the best eyesight they’ve had in years. In fact, nearly 9 out of 10 people do not require glasses after receiving a TECNIS® Multifocal implantable lens.2
Q: Am I a candidate for the TECNIS® Multifocal Lens?
A: If you’ve been diagnosed with cataracts, you may be a candidate for the TECNIS® Multifocal Lens. Whether theTECNIS® Multifocal Lens is the right choice for you depends on your personal preferences, lifestyle and the overall health of your eyes. Your doctor will make a recommendation following a complete eye exam.

Indication: TECNIS® Multifocal intraocular lenses are indicated for primary implantation for the visual correction of aphakia in adult patients with and without presbyopia in whom a cataractous lens has been removed by phacoemulsification and who desire near, intermediate, and distance vision with increased spectacle independence. The intraocular lenses are intended to be placed in the capsular bag.
Risks: As with many things, there may be a trade-off. If you decide to have a multifocal lens, your use of glasses may decrease, but at the cost of losing some of the sharpness of your vision. Even with glasses, this loss of sharpness may become worse under poor visibility conditions such as dim lighting or fog. There may also be some visual side effects, such as halos and glare from lights at night that are more common than with a monofocal IOL. Halos are rings of light that you may notice when looking directly at a source of light, such as oncoming car headlights. Glare is a scattered light effect that can appear around a source of light.
General risks with cataract surgery and IOL implantation: Whatever your lens choice, there are risks and possible complications of cataract surgery and lens implantation. Complications could be minor or temporary, or could permanently affect your vision. Complications are rare and may include the worsening of your vision, bleeding, or infection. Contact your eye doctor right away if you have any of the following symptoms after surgery: itching, pain, flashing lights, “floaters”, a “curtain” in your vision, redness, severe headache, nausea/vomiting, sensitivity to light, or watery eye.
PLEASE NOTE: Warnings and precautions accompany all IOLs because they are prescription-only medical devices. The following warnings and precautions apply to all multifocal IOLs.
Warnings: A very small number of patients (less than 1% in U.S. clinical studies) may be dissatisfied and request removal of their multifocal IOL. Under poor visibility conditions, your vision may be reduced more than it would be with a monofocal IOL. Under these conditions, you may have more difficulty recognizing some traffic signs and hard-to-see objects in the road. Therefore, you may need to take extra care when driving, especially in poor light conditions. In rare instances, multifocal IOLs may make some types of retinal surgery more difficult.
Precautions: If your eye is not healthy (including glaucoma), your vision may not be good even after your cataract is removed. In this case, you may not get the full benefit of the multifocal IOL. Before surgery, your eye doctor will check to see if you have any eye diseases. Be sure to tell your eye doctor if you have any health conditions that may affect your surgery or vision, and provide an updated list of medications to the doctor. There is a chance that your vision with a multifocal IOL may not be good enough to perform very near or detailed “up-close” work without glasses. The TECNIS® Multifocal IOL is designed for near vision at approximately 13 inches. Take all prescribed medicines and apply eye drops as instructed. You should avoid any activity that could harm your eye while you are recovering from surgery. Before and after the surgery, your eye doctor will tell you about activity restrictions. If you wear contact lenses, your eye doctor may ask you to discontinue wearing your lenses prior to being evaluated for the multifocal IOL. There were no patients 21 years old or younger included in the clinical study. As a result, there are insufficient data to support safety and effectiveness of this IOL in this age group.
Adverse events: The most frequently reported adverse event that occurred during the clinical trial of the TECNIS® Multifocal lens was macular edema, which occurred at a rate of 2.6%. Other reported reactions occurring in 0.3%–1.2% of patients were inflammation of the eye and secondary surgical intervention (including biometry error, retinal repair, iris prolapse/wound repair, trabeculectomy, lens repositioning, and patient dissatisfaction).
