Implantation of a disc lens in the capsular bag

We report a series of 65 cataract extractions with implantation of a rigid, posteriorly vaulted, disc-shaped lens in the capsular bag. Eight-nine percent achieved 20/40 vision or better, and 54% achieved 20/20 vision or better. The lens remained well centered in all cases. The method is described, and the practical and theoretical advantages of implantation of a lens approaching a natural shape are discussed.
