What are the different types of lens implants?
Intraocular lenses are broadly grouped into monofocal lenses, which focus at one distance, multifocal and extended depth of focus lenses, which spread the focus over a range, and toric versions of each, which correct astigmatism.

In more detail
The choice is a trade-off rather than a hierarchy. Lenses that extend the range of focus can reduce dependence on glasses, and they can also introduce halos or reduced contrast that not everyone tolerates. Which is the better lens depends on your eyes, your habits and how you feel about the trade.
