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.

Abstract: A polymer material is provided that can be used to produce an intraocular lens having a high refractive index and low adhesion on a lens surface and suppressing the occurrence of glistening and sub-surface nano glistening. Further, an intraocular lens with the properties mentioned above is provided. The polymer material can preferably be used to produce an intraocular lens. The polymer material is formed by polymerizing a liquid monomer mixture containing 11 to 30% by mass of a macromonomer (A) represented by the following formula (I) and at least a (meth)acrylate monomer (B) with an aryl group. [In the formula, four n respectively and individually representing 1 or 2, a, b, c, and d being respectively and individually integers of 4 or more, and four Z being respectively and individually substituent groups containing a (meth)acryloyl group.
