Simulation of angularly and radially segmented multifocal patterns in an adaptive optics simulator, published in Vision Research.



We evaluated, optically and psychophysically, the quality provided by multizone radial and angular segmented phase designs in 8 subjects using a custom-developed Adaptive Optics (AO) We found that 2-zone segmented designs (angular & radial) provided better performance for far and near vision, 3- and 4-zone segmented angular designs performed better for intermediate vision. AO-correction of natural aberrations of the subjects modified the response for the different subjects but general trends remained. 

The Adaptive Optics Visual Simulator developed in the current study allows evaluating vision with any multifocal solution, while controlling the natural aberrations of the subject and  allows a better understanding of optical and visual interactions in multifocal simultaneous vision corrections, and to investigate whether these interactions are driven by optical or by neural effects, These results are important to improve intraocular lens design and to select the optimal design for a patient.
