Lens Implants | Multifocal Lens | TECHNIS® Multifocal
The TECHNIS™ multifocal lens procedure is an advanced treatment for cataracts that helps most people see near, far and everything in between without depending on glasses all the time.
The lens is a clear, foldable implant made of a high-refractive-index acrylic material, which has been specially designed with multifocal zones that provide good vision across any distance, and in any light condition -- even in low light.
FREQUENTLY ASKED QUESTIONS ABOUT TECHNIS® MULTIFOCAL LENS AND THE PROCEDURE
Will I still need to wear glasses if my surgeon recommends a TECHNIS® multifocal lens?
The results will vary depending upon your vision, lifestyle and the anatomy of your eyes. Most people find that they need glasses to read small type. Some may require glasses for night driving. Most people, however, can go to the store or conduct many of their day’s activities without depending on glasses. In a clinical study, 92% of those who received the technology in TECHNIS™ Multifocal Lenses never or only occasionally needed to wear glasses.
How is the TECHNIS lens different from traditional monofocal intraocular lenses?
The TECHNIS multifocal lens is a multifocal intraocular lens. Unlike traditional monofocal (single-vision) lens implants, the TECHNIS lens provides quality vision at all distances – near (reading), intermediate (computer use or cooking), and far (driving).
Traditional monofocal lenses usually provide good vision only at a distance with limited ability to see objects that are near without glasses. Unlike other earlier multifocal lens designs, the TECHNIS multifocal lens has proportioned the size of its zones to provide for good vision in a range of light conditions. For instance, some zones have been designed to offer greater low light/distance vision support during night driving.
How does the TECHNIS lens replace the cataract?
The natural lens inside the eye is gently removed through a tiny incision in the periphery of your eye’s cornea (the clear windshield to the eye). The cataract-impaired lens is then removed through this incision and the lens implant is inserted in its place to permanently replace it. The procedure usually takes about 15 to 45 minutes and vision is usually improved the day after surgery. The vision usually continues to improve the first few weeks after surgery.
What if my medical history or current medication prevents me from considering an injection of local anesthesia?
Today, anesthesia may also be administered topically, with eye drops. In the majority of cases, no injection is required. Our specialist can tell you if this is an appropriate option for you.
How long after surgery until I see my best?
Like most procedures, this depends upon the overall health of your eye. For most people, vision is noticeably the day after surgery and continues to improve during the first few weeks after the procedure.
Does the TECHNIS lens require an adjustment period?
Yes. For most people there is a period of weeks when your brain is learning to see up close and at a distance with the new lens. This adjustment period is usually complete within 6 to 12 weeks. Also, like all multifocal lenses, some people report halos or glare around lights. Again, for most people this diminishes over time. For some, it becomes less troublesome but never completely goes away. Most people report that the ability to see near, intermediate and far outweighs any visual side effects associated with the lens.
Are there any risks of having the TECHNIS lens procedure?
As with any surgical procedure there are risks. The biggest risk with any cataract procedure is infection. Fewer than 1% of patients having a lens implant procedure ever get an infection and most are treated successfully with medications. Infections, however, can cause a severe or total loss of vision.
