Abstract:
A lens for refractive tear shaping, having a curved lens body with a peripheral edge and a central opening therein. The central opening is shaped and sized and has a tear shaping edge structured to form a tear meniscus within the central opening. The tear meniscus being formed by interaction of a tear film of the eye and the tear shaping edge and having a posterior curvature conforming to an anterior corneal curvature and an anterior curvature. The anterior curvature is dependent on the size and shape of the central opening and structure of the tear shaping edge.
