20130335701 | LENSES, SYSTEMS AND METHODS FOR PROVIDING CUSTOM ABERRATION TREATMENTS AND MONOVISION TO CORRECT PRESBYOPIA - A lens, system and/or method for providing custom ocular aberrations for enhanced higher visual acuity. Scaled versions of a patient's aberration pattern may either attenuate or amplify the overall amount of ocular aberrations, to either correct or partially correct a patient's aberrations leading to enhanced visual acuity and/or extended depth of focus. This may be binocularly applied in order to provide high visual acuity in a patient at least at near, far and intermediate distances. The method may include obtaining an optimized binocular summation of both eyes of the patient; designing a first lens solution to correct or partially correct the dominant eye's aberrations according to an attenuated scaled version of a patient's ocular aberrations in the dominant eye; and designing a second lens solution to provide an additional customized extension of depth of focus by the induction of scaled patterns of ocular aberrations in the non dominant eye. | 12-19-2013 |
