Is pupil size a consideration when choosing a lens for cataract surgery?
may be a consideration when choosing certain types of intraocular lenses (IOLs)

. The Light Adjustable Lens (LAL) requires at least a 7 mm dilated pupil, so the power can be adjusted after surgical healing. Pupil size can also affect the performance of multifocal IOLs. A too small pupil may decrease the sharpness of near and intermediate vision, while a bigger pupil may cause problems with glare and distance vision.
