pseudoaccommodation

pseudoaccommodation 

Attainment of functional near vision in an emmetropic or distance-corrected eye without changing the refractive power of the eye. It may occur when the pupil is very small thus increasing the depth of field, in a presbyopic eye corrected with a progressive addition lens, in a pseudophakic eye corrected with a multifocal intraocular lens implant (IOL), or occasionally as a result of spherical aberration or astigmatism induced by corneal incisions made to insert an IOL.

Some of this variability can be accounted for by differences in an individual patient's lens but also pseudoaccommodation due to pupil size and non-refractive aberrations can also increase the depth of focus.
