To evaluate clinical outcomes of unilateral implantation of a diffractive multifocal intraocular lens (IOL) in patients with contralateral monofocal IOL. Twenty-two patients who already had implantation of a monofocal IOL in unilateral eye underwent implantation of a diffractive multifocal IOL in contralateral eye were enrolled. After 1, 6, and 12mo, uncorrected and distant corrected distant visual acuity (UCDVA and DCDVA), uncorrected and distant corrected intermediate-visual acuity (UCIVA and DCIVA), uncorrected and distant corrected near visual acuity (UCNVA and DCNVA), and contrast sensitivity were obtained. Halo/glare symptoms, spectacle dependence, and patient satisfaction were also evaluated. The mean age was 67.86±7.25y and the average interval between two IOL implantations was 645.82±878.44d. At 1mo, binocular UCDVA was lower than 0.20 logMAR in 76% of patients (mean 0.12±0.13 logMAR), which increased to 90% by 6 and 12mo. The binocular UCDVA was significantly better than the monocular results (
