Intraocular lenses (IOLs) are very small devices—with optics usually about 6.0 mm in diameter—that are used to replace the natural crystalline lens of the eye when it becomes clouded due to a cataract. When clouding occurs, light can no longer pass clearly through the eye to focus on the retina.
Approximately 15 million IOLs are implanted worldwide each year.
Prior to FDA approval of presbyopia-correcting IOLs that correct for distance, intermediate, and/or near vision, IOLs provided correction of vision at one plane—usually distance vision. Patients were required to wear glasses, bifocals, or trifocals for intermediate and near vision.
The TECNIS® Multifocal Lens
The TECNIS® Multifocal Lens is implanted in the eye and replaces the cataractous natural crystalline lens. The lens is normally implanted in both eyes.
The TECNIS® Multifocal Lens is designed to provide high-quality vision at all distances:
- Distance vision for driving, golfing, sightseeing
- Intermediate vision for computer use, cooking, talking face-to-face
- Near vision for reading, knitting
- Most people receiving the TECNIS® Multifocal Lens technology don’t need to depend on glasses for daily activities
- 90% of patients are able to function comfortably without glasses at ALL distances
- Nearly 9 out of 10 patients NEVER wear glasses
Due to advanced technology, the TECNIS® Multifocal Lens provides excellent vision in low-light environments, such as reading a menu in a restaurant and driving at night.
Immediately after surgery, some people may experience rings around lights when driving at night, but this typically lessens or goes away over time.
