Abrégé
(EN)
Devices systems, and methods can measure, diagnose and/or characterize an eye of a patient, including physiologic and optical properties, such as hydration and tear volume in relation to an optical surface of the eye, including topography of a corneal surface of the eye and/or a wavefront elevation map of the eye. The system forms an image of a tear meniscus along an eyelid. The eye can be illuminated so that the meniscus appears as a dark band in the image. Tear volume can be determined by measuring a height across the tear meniscus. The tear volume can be used to determine the optical properties of the tear of the eye and to diagnose conditions of the eye. The patient can be screened for treatment of the eye with refractive surgery using a measured pupil size, hydration and topography and/or wavefront.
