Types of Intraocular lenses (IOLs):

All IOLs include fitters against the UV lights.

1- MonoFocal IOL:
The most common type with one power set most of the time for distance. (it can be set for near or intermediate if the patient request it). Glasses will be used to correct for near vision if the IOL set for distance. some patient elect to have " Monovision" by set the IOL for one eye for distance and the other eye for near.

2- Multifocal IOL:
Multiple focal zones are designed into the IOL (Intraocular lens) that enable the patient to see both near and distance vision. These IOLs reduce but not eliminate the need for reading glasses (reading glasses May be needed for very fine print). It takes 6-12 weeks to adapt to these lenses.

The success of these IOL depends to the patient pupil size and the degree of astigmatism. The possible side effects are seeing glare, halos around the light, decreased sharpness of vision (decreased contrast sensitivity) especially at night.

3- Toric IOL for astigmatism
Astigmatism (type of irregularity in corneal curvature) can lead to vision distortion.

Toric IOL is a monofocal IOL with correction of astigmatism built into it.
