Question:
Is pupil size a consideration when choosing a lens for cataract surgery?
Answer:
Pupil size may be a consideration when choosing
certain types of intraocular lenses (IOLs) before
cataract surgery. 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.
