Evaluation of the True Wavefront Aberrations in Eyes Implanted With a Rotationally Asymmetric Multifocal Intraocular Lens published in Journal of Refractive Surgery
Is it possible to separate the wavefront aberrations of the eye from the multifocal intraocular lens pupillary power distribution after a cataract surgery? Our recent paper answers this question using OCT and LRT measurements in the case of a commercially available rotationally asymmetric segmented refractive multifocal intraocular lens, Lentis Mplus (Oculentis GmbH, Berlin, Germany). Custom analysis of ray tracing–based retinal spot diagrams allowed decoupling of the true higher order aberrations of the patient’s eye from the power pupillary distribution of the Lentis Mplus IOL, therefore providing the appropriate phase map to accurately evaluate through-focus optical quality. The method was tested using ray tracing optical simulations in a computer eye model virtually implanted with the Lentis Mplus IOL, with a generic cornea or with anterior segment geometry obtained from custom quantitative spectral-domain optical coherence tomography in a real patient. The method was applied to laser ray tracing aberrometry data at near and far fixation obtained in a patient implanted with the Lentis Mplus IOL.
