PURPOSE: To evaluate the visual outcome, spectacle independence, and patient satisfaction after implantation of two Acrysof ReSTOR (Alcon Laboratories, Inc., Fort Worth, TX) intraocular lenses (IOLs) with different addition power or their combination in both eyes. METHODS: One hundred twenty eyes of 60 patients with bilateral multifocal IOL implantation were divided into three groups of 20 consecutive patients each: the SV25T0 (the T0 group), the SN6AD1 (the D1 group), or a combination of both the SN6AD1 and SV25T0 (the combined group). Patients were observed 18 months postoperatively for visual acuity (40, 50, and 60 cm, and 4 m), defocus curves (range: +1.0 to −4.0 diopters), and contrast sensitivity. Quality of vision, patient satisfaction, and spectacle independence were evaluated by the National Eye Institute Refractive Error Quality of Life Instrument-42 questionnaire. RESULTS: The D1 group achieved better results for near vision ( P < .01), whereas the T0 group achieved better intermediate vision ( P = .01). The combined group showed a wider range of spectacle independence at all distances evaluated ( P < .05). The contrast sensitivity was similar within the groups. The incidence of glare was lower for the T0 group ( P = .054). The combined group had better results in terms of expectation ( P = .021) and activity limitation ( P = .003). CONCLUSION: Although the bilateral implantation of the same multifocal IOL can maximize the vision for near or intermediate distances, the combination of these IOLs in both eyes can increase the range of spectacle independence without compromising the contrast sensitivity and quality of vision.
