Tecnis® Intraocular Lens
In the past, you had to accept that your vision would be better after cataract surgery, but never as good as your vision before you developed cataracts. However, advanced technology now gives you many options for getting vision that is comparable to, and in some cases better than, you had before developing cataracts. Tecnis® is a multifocal lens designed to give you great vision at all distances after cataract surgery.
This page will help you understand how Tecnis® works, including its benefits and disadvantages, but it will not be able to tell you whether it is the right lens for you. To talk to an ophthalmologist about which intraocular lens (IOL) is the best solution for your vision, please contact Silverstein Eye Centers to schedule a consultation at our Kansas City location.
How Tecnis® Works
When your natural lens becomes clouded by cataracts, there is no way for it to be made clear again. Cataract surgery involves removing the eye’s natural lens and replacing it with an artificial lens. When this happens, the eye loses its ability to accommodate or change focus to look at objects at different distances. There is one replacement lens, Crystalens®, that comes closest to replicating this ability, but Tecnis uses a different technique to give you clear vision at all distances.
Tecnis is a multifocal lens, meaning it focuses light from many different distances on your retina at the same time. When you look at an object, there is not one, but many images on your retina – one that is clear, and many that are unfocused. Your brain simply picks the clear image, and that’s what you see. This may seem complicated, but it’s actually a visual trick that your brain performs all the time.
Benefits of Tecnis®
Tecnis® is the first lens designed using wavefront mapping of the cornea. This advanced optical technology that has improved the ability of LASIK to correct higher-order aberrations has the potential to give you clearer vision after cataract surgery. The goal of Tecnis is to counteract aberrations in your cornea to give you sharper vision than other types of intraocular lenses.
Tecnis gives great close and distance vision. In fact, it has been shown to improve functional vision in night-driving conditions. Your vision results may vary, but there are a number of studies that indicate the technology behind Tecnis does give overall better vision correction.
Disadvantages of Tecnis®
Tecnis is a multifocal lens, which means that your brain has to adapt to a new way of seeing. This may take some time, and a very small number of people find they are simply unable to adapt. Tecnis is designed for “near vision” at 13 inches, and visual tasks closer than that distance may require the use of glasses.
