If you or someone you know has been diagnosed with cataracts, you are not alone. Millions of people worldwide have reduced vision as a result of cataracts. This site will help you better understand how your eyes change with age, what a cataract is, how the cataract procedure is performed and why the TECNIS® lens may be right for you. Click on one of the links and get on the road to safer, sharper vision.

Indications and Important Safety Information



TECNIS® lenses are indicated for the visual correction of aphakia in adult patients in whom a cataractous lens has been removed by extracapsular cataract extraction. These devices are intended to be placed in the capsular bag.

General risks with cataract surgery and IOL implantation

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.


Physicians considering lens implantation under any of the following circumstances should weigh the potential risk/benefit ratio:

1. Patients with recurrent severe anterior or posterior segment inflammation or uveitis.
2. Patients in whom the intraocular lens may affect the ability to observe, diagnose or treat posterior segment diseases.
3. Surgical difficulties at the time of cataract extraction, which may increase the potential for complications.
4. A compromised eye due to previous trauma or developmental defect in which appropriate support of the IOL is not possible.
5. Circumstances that would result in damage to the endothelium during implantation.
6. Suspected microbial infection.
7. Patients in whom neither the posterior capsule nor the zonules are intact enough to provide support for the IOL.
8. Children under the age of 2 years are not suitable candidates for intraocular lenses.


Physicians should not resterilize or autoclave the lens. Only sterile irrigating solutions such as balanced salt solution or sterile normal saline should be used to soak the lens prior to implantation. Physicians should not store the lens in direct sunlight or over 45°C.

Adverse Events

Adverse events occurred at rates between 1.6% and 3.3% during the clinical trials for TECNIS® IOLs or their “parent” IOLs. These events included macular edema, endophthalmitis, anterior lens tissue ongrowth, lens dislocation, hypopyon, corneal edema, iritis, hyphema, secondary glaucoma, and secondary surgical intervention.
