Purpose To report the preliminary efficacy and safety of zero diopter (D) intraocular lens implantation in highly myopic eyes. Design Retrospective surgical case series. Methods Three highly myopic eyes with axial lengths greater than 30 mm were implanted with zero D Alcon model MA60MA 3-piece acrylic posterior chamber lenses at the time of cataract surgery. Results Uncorrected visual acuity improved from counting fingers to 20/20− and 20/40− in two eyes. Best-corrected visual acuity improved from 20/80 and 20/60+ to 20/20− in the same eyes. A third eye was at counting fingers before and after surgery, because of a staphyloma. The range of preoperative, intended postoperative, and achieved postoperative spherical equivalent refractive errors was −15.1 to −25.0 diopters, −0.20 to −1.44 diopters, and +0.13 to +0.50 diopters respectively. Conclusions All eyes experienced mild hyperopic refractive errors after surgery. No retinal detachments occurred during the follow-up interval.
