Although all intraocular lenses are used to restore clarity of vision, there are many intraocular lens choices available to patients today.
Standard lens implants are monofocal, meaning they are designed to correct the vision at one focal length. If a patient chooses to have IOLs implanted that correct for distance vision in both eyes, they will most likely need glasses to read. Some patients opt for an IOL that corrects their vision for distance in one eye and an IOL that corrects their vision for near in the other eye.
Premium IOLs include the presbyopia-correcting IOLs and the toric IOLs. The decision to use these lenses must be made on an individual basis.
Presbyopia-correcting intraocular lenses are designed to correct for distance and near vision. The intended goal of these lenses is to decrease the need for glasses.
Toric intraocular lenses are used for those patients with astigmatism. Astigmatism refers to an irregularity in the curvature of the cornea. Toric IOLs are designed to correct distance vision and astigmatism.
