A retrospective study of 330 cataract surgery patients was undertaken to verify some of the differences between men and women. Six parameters were analyzed: the age of the patient at the time of surgery, the axial length, the lens implant power selected for emmetropia, the keratometry readings, and the corneal astigmatism. We found only one significant difference between the male and female groups. More women required cataract surgery than men by a 2:1 ratio. There were no significant differences in the other parameters. We conclude that these parameters need not be considered in the decision-making process regarding cataract and intraocular lens implant patients.
