ABSTRACT:
A toric intraocular lens is provided to eliminate or substantially reduce the expected postoperative astigmatism induced by eye surgery. The lens is constructed such that the finally placed vertical meridian is optically weaker than the horizontal meridian. The lens is constructed to ensure that the vertical meridian will be properly aligned when placed in the eye, such as by disposing the haptics along the vertical meridian.
