Purkinje Imaging System to Objectively Measure Corneal Haze and Lenticular Scattering


Ocular scattering increases with age, surgery and some pathology. Although physical changes in the cornea, the lens, the retina and the humors might contribute to alter the amount of ocular scattering, most techniques estimate the total ocular scatter without discriminating the different contributions. Here we describe a Purkinje imaging instrument that permits to objectively measure the amount of scattering associated with the cornea and the lens, avoiding the contribution from the retina.
