However, they are less effective at achieving glasses independence when compared to multifocal IOLs, because their range of focus is more limited.
Currently, Crystalens and Trulign Toric IOLs are the only FDA-approved presbyopia-correcting IOLs for cataract surgery that improve near vision by a focusing process called accommodation.
This is uncommon, but if you choose one of these lenses, you should be prepared for this possibility.

However, you should expect to wear glasses for near work (reading, dialing the phone, operating the television remote, etc.) These lenses work well with a small amount of monovision to increase the range of focus to include near vision, but you must be a suitable candidate for monovision to receive this treatment option.
An accommodating intraocular lens (IOL) allows a patient to see at different distances without needing to worry about using glasses or readers.
