1) Monofocal IOLs – These lenses provide good distance vision and most patients are not dependent on their distance glasses for daily activities. However, patients implanted with monofocal IOLs typically require reading glasses after cataract surgery.
In the recent years, monofocal lenses have been designed with aspheric surfaces. These state-of-the-art FDA approved aspheric or aberration-free IOLs greatly improve image quality by enhancing contrast, eliminating glare and haloes, and improving night vision.
2) Toric IOLs – These special lenses correct high cylindrical powers reducing the patient’s dependence on distance glasses.
3) Multifocal IOLs and Accommodative IOLs – These lenses are designed to provide good unaided distance and near vision with less dependence on glasses.
