Abstract: Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes determining a deviation in position of at least one optical element from a reference line corresponding to alignment of the apex of the cornea, center of the pupil, center of the IOL, and fovea, and/or determining a tilt of at least one of the optical elements relative to the reference line. The method can further include applying a plurality of focused laser pulses to a selected area of the implanted IOL to produce, through refractive index writing, a phase change pattern on the IOL that is configured to compensate for the deviation(s) and/or tilt to improve the foveal vision of the subject.

Abstract: Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method for vergence matching includes calculating vergence of a wave after refraction on a surface of an IOL and, based on an estimated curvature, converting an initial phase map into a vergence-matched phase map, such that the initial phase map follows the curved vergence of the wavefront.

Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects.

Abstract: Lenses and methods are provided for improving peripheral and/or central vision for patients who suffer from certain retinal conditions that reduce central vision or patients who have undergone cataract surgery. The lens is configured to improve vision by having an optic configured to focus light incident along a direction parallel to an optical axis at the fovea in order to produce a functional foveal image. The optic is configured to focus light incident on the patient's eye at an oblique angle with respect to the optical axis at a peripheral retinal location disposed at a distance from the fovea, the peripheral retinal location having an eccentricity between ?30 degrees and 30 degrees. The image quality at the peripheral retinal location is improved by reducing at least one optical aberration at the peripheral retinal location. The method for improving vision utilizes ocular measurements to iteratively adjust the shape factor of the lens to reduce peripheral refractive errors.
