Abstrakt: A 58-year-old airline pilot had cataract surgery with implantation of a posterior chamber intraocular lens with four positioning holes around the optic edge. During periods of maximum pupil dilation, such as at night, visual aberrations including glare, monocular diplopia, and haloes occurred and he was unable to work in his occupation. The symptoms were severe enough that lens exchange was required, and a posterior chamber lens with no positioning holes was successfully implanted. The symptoms immediately subsided postoperatively and his last known visual acuity was 20/15. This case, and the report of another patient with similar postoperative problems, illustrates that implantation of lens optics with a larger effective optical zone for posterior chamber lens implantation is desirable. This is particularly true now that younger, more active patients, many still engaged in occupations, are having lens implantations.
