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. |
