Once the cloudy human lens is removed, an intraocular lens ( IOL) is inserted in it's place. IOL's - smaller in diameter than a dime - are made from thin flexible acrylic and are designed to last your entire lifetime without replacement. IOL's have an optical power -- like glasses or contacts -- to help you see clearly. Many patients have much less reliance on glasses after surgery thanks to their IOL's.
There are two classes of IOL's to think about before you have surgery. The standard IOL is a single focus implant that can improve your focus for distance vision. These IOL's are covered by insurance. While they provide excellent vision they do have some limitations in that they: do NOT correct for astigmatism and do NOT allow for close up vision. Consequently, patients with these IOL's will require reading glasses and possibly distance glasses.
The second class of IOL's are are Premium IOL versions of standard implants. Their enhanced designs can correct for corneal astigmatism and allow various degrees of close up reading power to allow you to see distance and near vision without relying on glasses. Premium IOL's one time costs are not covered by insurance.
Corrects for general distance correction but not astigmatism
Does not correct for intermediate or near vision (computer and reading)
Reading or bifocal type glesses are required after surgery
Covered by standard insurance with surgery
Corrects for almost all refractions, including those with astigmatism
Will allow for various levels of intermediate and reading without glasses
Enhances natural vision with greater depth of field than standard IOL
IOL's are typically not covered by insurance
