PURPOSE: To evaluate binocular visual function, refraction, and subjective outcomes of intermediate optimization of vision after simultaneous bilateral implantation of the nonaspheric AcrySof SA60D3 ReSTOR multifocal @entity2790 ( @entity2790 ). SETTING: Private clinic, Abbotsford, British Columbia, Canada. METHODS: Intermediate optimization was performed by overcorrection of 1.00 diopter (D) to induce mild @entity1714 in the nondominant eye in @entity1 having bilateral implantation of the multifocal @entity2790 . Distance manifest refraction and visual acuity at several distances were determined; contrast sensitivity function (CSF), near-point stereo acuity, and subjective outcomes were assessed postoperatively at 2 weeks and 1, 3, 6, and 12 months. RESULTS: Thirty-two @entity1 with intended intermediate optimization and 5 @entity1 with unintended intermediate optimization were prospectively evaluated. The mean manifest refraction spherical equivalent was stable from 2 weeks (-0.94 D+/-0.22 [SD]) to 12 months (-0.93+/-0.23 D) in the intermediate optimization eyes. Overall, postoperative mean binocular uncorrected near, intermediate, and distance visual acuities were 20/23, 20/23, and 20/22, respectively. No significant differences were found between best distance-corrected and uncorrected stereo acuity or between best distance-corrected and uncorrected binocular CSF under most conditions (P> .05). On questioning, 97% of @entity1 had little or no difficulty seeing and were bothered occasionally or never by the visual fluctuation between the near range and intermediate range. CONCLUSION: Intermediate optimization with slight @entity1714 in 1 eye after bilateral implantation of the multifocal @entity2790 offered consistent good vision at all ranges, indicating it a safe option for @entity1 who require good vision at intermediate ranges.
