What Are Extended Depth Of Focus Lenses?

The premier way to get cataract surgery or refractive lens exchange these days is to get a lifestyle or premium lens. Getting a special lens during your surgery unlocks vision that just isn't possible with the older and more basic style of lenses. Toric lenses can correct astigmatism to provide the best distance vision. Multifocal lenses came along to provide good up close vision as well. There is now a third type of lens in our vision correction toolbox called the extended depth of focus lens.

Multifocal lenses work by splitting light. Part of the light goes towards distance vision, part towards computer and part for up close. These lenses work very well. The PanOptix by Alcon is an example of a multifocal lens. A byproduct of splitting the light is some night time driving symptoms such as halos and starbursts which gradually fade away over time.

Extended depth of focus lenses are an alternative way to provide more range to the vision without splitting the light. Instead of focusing on a single point like the older basic lenses, these lenses stretch out the focus to cover more distance. The Vivity lens, recently released by Alcon, achieves this goal. And the cool part about this lens is it does it without creating difficult night time symptoms!

The great part about extended depth of focus lenses is that they improve our ability to meet vision needs after cataract surgery and refractive lens exchange. But this still isn't a one size fits all approach. While extended depth of focus lenses work best for some, toric lenses and multifocal lenses work best for others. But no need to worry, visiting an experienced refractive surgeon can sort it all out for you!
