    • 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.
    • 装置系统和方法可以测量,诊断和/或表征患者的眼睛,包括生理和光学性质,例如相对于眼睛的光学表面的水合和泪液体积,包括眼睛的角膜表面的形貌 和/或眼睛的波前高程图。 该系统沿着眼睑形成泪液半月板的图像。 可以照亮眼睛,使得半月板在图像中呈现为暗带。 撕裂体积可以通过测量穿过泪液半月板的高度来确定。 撕裂体积可用于确定眼睛撕裂的光学性质并诊断眼睛的状况。 可以使用测量的瞳孔大小,水合和地形和/或波前来对患者进行屈光手术的眼睛治疗。
