摘要
An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.
