For a number of years a special lens has been employed after operation for cataract. It gives fair vision to a number of aphakic patients. It can be used the day after operation, but ordinarily it is given at the first posthospitalization visit of the patient to his ophthalmic surgeon. This lens has an additional advantage in that it limits ocular rotation. It might therefore help forestall retinal separation and other postoperative complications.

Description of the Lens  The lens is 30 mm. in diameter and has a paper-thin edge. Its proximal curvature equals −6.00 D. sph, and its distal curvature equals +18.00 D. sph. Thus the effective refractive power of the lens is +12.00 D. sph. It fits readily on the outside of the patient's own glasses, which frequently have a base curve of +6.00 D. sph.

Use of the Lens  The lens is placed on the patient's old glasses
