Cataract surgery lens implant options have have changed over new years to give you more selection as to how to definite your vision after surgery. The only selection used to be a clear lens to replace the removed lens and coke-bottle glasses to be able to see well. Intraocular lens implants (Iols) have changed that by allowing the surgeon to replace the clouded cataract lens with a remedial lens. There are also options as to what type of lens to use depending on what type of vision you want to have after surgery. Do you want monovision, monofocal, multifocal, accomodating, or Toric? Each has distinct functions, let's take a look at them.
[b]Lens[/b]Monovision. Monovision is not a lens, but a type of correction. It means one eye is corrected for close vision and the other for far vision. Monofocal lenses are commonly used for this type of correction. Many people adapt well to this type of correction, especially if they have been wearing touch lenses with this type of correction former to surgery.
Monofocal. A monofocal lens has one power of correction and is normally used to definite whether nearsightedness or farsightedness, similar to touch lens correction.
Multifocal. Multifocal lenses have 2 distinct powers of correction, one in the center and the other power in the periphery so the eye can be corrected for both near and far vision. Similar to the concept of bifocal glasses.
Accomodating. Accomodating implants are made to turn shape when you focus on something close up like reading. Similar to monofocal lenses in that they only have one power of correction.
Toric. Toric lens implants have 2 focus points instead of one, similar to multifocal lenses. These are used to definite astigmatism like your glasses, but within the eye itself. The Toric lens implant will not definite close or far vision unless set for monovision.
As you can see there are a lot more options for cataract surgery lens implants than there used to be. Talk to your eye surgeon about which selection would work best for you.
