Advances made in intraocular lens technology in the past few years have accounted for a dramatic decrease in complications and restoration of vision as has never been possible with glasses or contact lenses.Criticism of the currently used intraocular iris- or capsule-mounted lens devices is out of date and applicable only to the earlier, mechanically primitive implants. It is analagous to complaining of the limitation of computers because of their weight, size, heat production, and energy consumption. This may have applied in 1950, but today, a computer of the same capacity—and better—can literally be held in the hand.We are now working with "third generation" lenses—past the Ridley lens and
