Abstract
An intraocular lens with an iris retention loop that is attached to an optical section of the lens by a pair of shank sections. Each shank section has a noncircular cross sectional area to provide a more flattened contact surface for engaging an inner edge of the iris. Such structure reduces cutting of the iris when the iris is stretched over these shank sections to retain the lens in the eye.
