Ocular optical quality dynamics during accommodation in subjects with accommodative dysfunctions

Abstract

Complaints of blurred distance vision after performing a near-vision task are common in the optometric practice. Several of these subjects showed no alterations in the optometric tests that are normally performed. In this work a new technique to study the accommodative response to different stimulus is presented. Ocular accommodation is evaluated from ocular wavefront aberrations that are continuously measured during the response to different accommodative demands. Several accommodative parameters can be computed from the collected data: accommodative response, lag of accommodation, latency, response time. These parameters are computed for both accommodation and disaccommodation process and results are present for subjects with accommodative disorders before and after a visual therapy program was applied. The results could help us perform an early diagnose, better understand the accommodative dysfunctions and objectively evaluate the results of vision therapy in the treatment of these conditions.
