Neuroadaptation of presbyopia-correcting intraocular lenses

Abstract

Purpose of review: Advances in the design of intraocular lenses give options to patients for some return to the optical accommodation needed to focus on objects at different distances. Technology is only improving these options for presbyopic-correcting intraocular lenses. Surgeons must consider the possible neuroadaptation abilities in patients that may help in the success of using these lenses.

Recent findings: The hierarchy of the visual system allows two disparate retinal images to combine to form a single picture with depth. Attempts to correct presbyopia with intraocular lenses add complexity to the pathway with the possible introduction of monovision or intraocular rivalry. The neuroadaptation involved in successful use of these lenses has not been study but has been well established in other neurologic processing.

Summary: Understanding what patient selection factors are important for neuroadaptation may contribute to outcome success.
