Abstract
Abstract Purpose To compare visual acuity, total and high order wavefront aberrations (coma, spherical aberration, and other terms of high order aberration), and contrast sensitivity in eyes implanted with the multifocal Restore IOL versus the multifocal Acrylisa IOL. Methods Patients were divided in two groups: group 1 (8 patients, 16 eyes implanted with Restor) and group 2 (15 patients / 30 eyes implanted with Acrylisa). All eyes were targeted for emmetropia. Complete ophthalmological examination, including uncorrected visual acuity (UCVA), best spectacle‐corrected visual acuity (BSCVA) was performed. Contrast sensitivity evaluation,and wavefront analysis, were performed with the Imagine Eyes IRX3 wavefront aberrometer. Measurements with the IRX3 were performed in triplicate in order to verify the robustness of the data. Results All eyes in all groups had BSCVA > or = 20/20 postoperatively. Measurements with the IRX3 were easily obtained. The triplicate measurements confirmed the robustness of the data. Mean total aberration root‐mean‐square (RMS) values and higher order aberrations (HOA) value were not significantly different between the two groups. Residual spherical aberration values were comparable in both groups and appeared inferior if to the ones previously obtained with non aspheric standard monofocal IOLs. Mean contrast sensitivity values were comparable in both groups. Conclusion The measurement of higher order aberrations in patients implanted with multifocal IOLs is easy and reproducible with the IRX3. There is no statistical difference between the values obtained in the 2 groups regarding RMS and HOA. Contrast sensitivity revealed similar values in both groups.
