New Technology Allows You to See Near and Far Without Glasses

If you have undergone cataract surgery, there are three primary methods that can allow you to see near and far. These include:

Monovision
Multifocal Intraocular lens (IOL)
Accomodating IOL

Monovision
This is a process of setting the focus of one eye on close-up objects and the focus for your other eye on far-away objects. In doing this, your brain combines the two images to create a clear picture.

Multifocal IOLs
These include the ReZoom, ReSTOR, and Tecnis lenses. Multifocal IOLs are lenses that have concentric rings of varying focal power, like a bullseye. Some rings provide focus for near objects, others for mid-range objects, and some for seeing objects at a distance.

The Tecnis Multifocal Foldable IOL also has concentric rings for different distances. It received FDA approval in January, 2009 for use in cataract surgery, where the natural lens is replaced. In the clinical trials most participants achieved 20/25 distance vision or better and 20/32 or better for near vision. It is designed using Wavefront data - the same precise level of information that is gathered when you are having Wavefront LASIK.

Accommodating IOLs

These lenses are designed to change focus. An accommodating IOL allows you to see distant objects, and then is can change focus and allow you to see objects that are close up. The only accommodating IOL approved in the United States is the Crystalens.

If you live in the Los Angeles area want to enjoy near and far vision, please contact our Los Angeles office today. Orange County ophthalmologist Dr. Khanna and his staff can help you find the IOL that is best for your condition and needs. Please call today to schedule your free vision screening.
