摘要
PURPOSE: To evaluate the optical quality of 3 multifocal intraocular lenses (IOLs): the Mini Well Ready progressive multifocal aspheric IOL, the AT LISA trifocal diffractive IOL, and the Fine-vision full diffractive trifocal IOL. SETTING: University of Valencia, Valencia, Spain. DESIGN: Experimental study. METHODS: An instrument designed for measuring real-time modulation transfer function (MTF) and IOL power was used to measure the optical quality of each IOL for 3.0 mm and 4.5 mm apertures. This instrument measures both sagittal and tangential MTFs. The optical quality of each IOL was evaluated with the MTF, through-focus MTF, defocus tolerance, Strehl ratio MTF, and relative percentage of light in each focus. These metrics were evaluated at best focus for each IOL. RESULTS: Through-focus graphs corresponding to trifocal IOLs showed 3 mean peaks. Nevertheless, the progressive multifocal aspheric IOL showed 2 main areas, 1 corresponding to distance vision focus and the other including both intermediate and near vision foci. CONCLUSIONS: The results obtained in the present study suggest that the progressive multifocal aspheric IOL might be considered for cataract surgery.
