Video-oculography to evaluate Dynamic Visual Acuity to subjects with Intraocular Lens implant as a treatment for high refractive errors

摘要

The purpose of this paper is to describe the methodology based on video-oculography used to evaluate changes in Dynamic Visual Acuity (DVA) in subjects with Intraocular Lens (IOL) implant. This is done before and later of the implant. The luminance conditions were established. The visual stimulus to show is copied from Lovie-Baley chart. Those are projected in front of the subject starting in a movement frequency of O.I Hz. It is gradually increasing until the subject refers is no possible to appreciate the stimulus form. A preliminary study is done in two subjects. The suggested methodology let to know frequency changes in DVA in subjects with IOL implant.
