Pupil Size Independence with Multifocal Contact Lenses: Fact or Fiction?

Key Points:

 

  • Multifocal (MF) contact lenses are designed to provide functional vision to presbyopic patients of different ages, refractive errors and pupil sizes
  • Pupil size decreases slightly with age; however, the correlation is weak and there is substantial variation among individuals 
  • There is no clinically significant relationship between pupil size and refractive error
  • Neither age nor refractive error are relevant with respect to multifocal optic zone designs 
  • A recent study showed that Alcon multifocal contact lenses are pupil size independent and demonstrated that pupil size did not affect the number of lenses required for a proper lens fitting or visual performance
