ABSTRACT:
The present invention is an intraocular lens for implantation into the posterior chamber of a human eye. The intraocular lens includes a plano-convex lens, which is formed from an optical material that is suitable for an implantable lens. The plano-convex lens is adapted to be inserted into the posterior chamber of the human eye within the capsular membrane thereof. The intraocular lens also includes a first supporting loop and a second supporting loop, which are formed from a material that is suitable for implantation into the eye, mechanically coupled to the peripheral edge of plano-convex lens and disposed at an angle in the range of 0.degree. to 25.degree. to the plane surface of the plano-convex lens so that their end portions are below the plane surface of the plano-convex lens. The second supporting loop has a notch which is disposed between the peripheral edge of the plano-convex lens and its end portions so that a temporary securement to the iris of the human eye may be accomplished.
