Research accommodating lens
They are much more successful at allowing “glasses free” reading than are the accommodating lenses that only allow most to read objects when they are further away, at about arm’s length or “computer distance”.
The primary disadvantage of multifocal lenses is that they can cause some halos and glare at night around lights.
These implants can provide better quality vision, especially at night.
Two examples are the AMO Tecnis and Alcon Acrysof® lenses.
In the past, all intraocular lenses were monofocal, which means that they only focused at one distance.
Most patients find this to be a wonderful way to enhance their lifestyle.
Many are not bothered by the haloing, and of those in whom it is more initially prominent, most find that they adapt or have the symptoms minimize or disappear with time.
In summary, we have found that if the goal is to see at distance and read up close well without glasses, the multifocal lenses tend to be the best choice.
There are traditional as well as “new technology” aspheric monofocal implants.
Unless there is a reason not to, we only use aspheric lenses.
