To evaluate near and far visual acuity, subjective visual symptoms, and patient satisfaction with a monocular implant of aspheric multifocal IOL (AMO Tecnis ZM900®).

Thirty eyes of 30 patients received phacoemulsifications and monocular implantation of Tecnis ZM900 IOL. The main outcome measures at postoperative 1 week, 1 month, 3 months, and 1 year were uncorrected and corrected near and distant visual acuity, refractory errors, contrast sensitivity, subjective visual symptoms (glare and halo), spectacle independency, and satisfaction.

At a 3 month postoperative visit, the mean uncorrected near and distant visual acuities were 0.29±0.17 (logMAR) and 0.16±0.12 (logMAR),respectively. At 1 year, the mean uncorrected near and distant visual acuities were 0.25±0.17 (logMAR) and 0.11±0.08 (logMAR). Glare and halo decreased, and contrast sensitivity increased upon 1-year follow-up after monocular implantation of ZM900. Most patients (87%) were satisfied with their visual outcome.

Monocular implantation of multifocal IOL Tecnis ZM900 shows stable surgical outcomes with a high satisfaction rate and enables a high rate of spectacle independency. Postoperative glare and halo, youth, and residual refractive error could be risk factors for dissatisfaction with monocular implantation of multifocal IOL Tecnis ZM900. Proper patient selection can lead to satisfying outcomes.
