Real-time measurement of ocular wavefront aberrations in symptomatic subjects

Te purpose of this work was to study the real-time changes of the optical properties of the eye with accommodation in subjects with symptoms of accommodative disorders. From ocular aberrations, it is possible to compute several parameters like the response and lag of accommodation. Te ocular aberrations were measured in 4 subjects, with diferent accommodative disorders, during several cycles of accommodation/disaccommodation and for diferent accommodative stimuli. Te measurement was done continuously and in real time during diferent accommodative stimuli. It was possible to see the changes in accommodative response during the several stimuli of accommodation. Subjects with accommodative disorders showed diferent accommodative responses. Te use of wavefront ocular aberrations can be a tool to diagnose accommodative disorders. In some subjects with complaints, this method showed irregularities even when the results of the usual clinical exams were normal.This work was supported by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UID/FIS/04650/2013.
