The first intraocular lens (IOL) that helps improve visual acuity at near, intermediate, and far distances for patients with cataracts has received FDA approval.
Conventional monofocal IOLs improve distance vision with 1 fixed focus point, but patients still need glasses for near and intermediate vision. Multifocal lenses that focus on 2 or more points may reduce or eliminate the need for glasses, but they’re more likely to cause adverse effects such as halos (http://bit.ly/2aeCiyT).
