What types of intraocular lenses are implanted?
Most intraocular lenses (IOL) are made of silicone or acrylic that has been coated with a material that helps to protect the eyes from harmful ultraviolet lights, one of the key functions of a natural lens. The types of IOLs available include:
Monofocal fixed-focus IOL
A monofocal intraocular lens provides clear vision at distant, intermediate, or near range. However, this lens can only correct vision in one of these ranges--not all three--at one time. Patients may correct distance vision but still need reading glasses.
A multifocal intraocular lens provides clear vision at multiple distances by incorporating different capabilities into various zones of the lens. These lenses can frequently be used to replace reading glasses.
A toric intraocular lens incorporates different vision capabilities in specific zones of the lens to correct the different refractive errors associated with astigmatism.
An accommodative intraocular lens is a type of monofocal lens that corrects vision at different distances by changing its position or shape inside the eye.
