Abstract: The present disclosure provides an orthokeratology lens. The orthokeratology lens includes a base curve zone, and a reverse curve zone, an adaptation curve zone, and a peripheral curve zone that are successively formed outward from a periphery of the base curve zone. A space defined between the reverse curve zone and a cornea varies periodically in a circumferential direction, and includes small spaces and large spaces that are cyclically and alternately disposed. Therefore, negative pressures applied on the cornea are different. As a result, a defocusing ring formed at a periphery in the cornea is not uniformly distributed. In comparison with a conventional orthokeratology lens, the orthokeratology lens of the present disclosure can produce higher-order aberrations during retinal imaging, which is more effective in slowing down growth of eye axes.

Abstract: A four-axis asymmetric orthokeratology lens includes a base curve zone, and a reverse curve zone, an adaptation curve zone, and a peripheral curve zone that are successively formed outward from a periphery of the base curve zone. A center of a circle of the base curve zone corresponds to a center of a cornea, and a zone, corresponding to the adaptation curve zone, of the cornea is defined as a specific annular zone. According to the four-axis asymmetric orthokeratology lens, four meridional lines of a lens body are determined based on a mean sagittal depth in the specific annular zone on the cornea. The four meridional lines divide the adaptation curve zone of the lens body into the four sector ring zones, and different curvatures are specifically set for each meridional line, to relatively independently design curvatures for curved surfaces of the four sector ring zones.
