• The iris-plane (Copeland) pseudophakos was evaluated in two 81-case surgical series. An early series consisted of the first 81 operations performed in the Miami community before a temporary moratorium on Oct 1, 1969. This series was compared with the first 81 operations performed after the moratorium was lifted on Oct 1,1971. The follow-up period of those available for study was 63 months in the early series and 19 months in the later series. Objectivity was assured since all surgery was performed by one author (N.S.J.) and all examinations performed by the other author (L.R.D.). Visual acuity of 6/12 or better was obtained in approximately 80% of patients. The most frequent problems encountered were recurrent iritis and cystoid macular edema. The optic benefit was apparent in this elderly group of patients who avoided the optical problems of aphakia.
