The Ridley lens has not been widely adopted, chiefly because of the technical difficulty of inserting the lens behind the iris and the increased hazard of postoperative complications that the procedure entails. But the idea of an intraocular artificial lenticulus to alleviate the disadvantages of aphakia and to correct high refractive errors in patients who retain the crystalline lens has stimulated a number of efforts to improve upon the Ridley lens.
