US Patent 11703695 Tear shaping for refractive correction
Article
A lens for refractive tear shaping, including a curved lens body defining an anterior partial thickness cavity indented into its anterior surface. The anterior partial thickness cavity has an anterior facing tear shaping surface structured to form a tear lens within the anterior partial thickness cavity. The anterior partial thickness cavity is structured to define a tear lens within the anterior partial thickness cavity by interaction between a tear film of the eye and the anterior facing base tear shaping surface. The posterior curvature of the tear lens is dependent on the shape of the anterior facing base tear shaping surface.
