Abstract:
An aspheric toric intraocular lens (IOL) having toricity and asphericity in a single lens. The toricity and asphericity may be provided on separate surfaces, such as an anterior surface and a posterior surface, or the toricity and asphericity may be combined onto a single surface. The edge thickness may be varied sinusoidal to maintain equal edge thickness at 45 degree meridian.
