Abstract: System and method for customizing multifocal ophthalmic lenses, such as an intraocular lens (IOL) or the like, that may be tailored for an individual patient or group of patients beyond the selection of a particular IOL power. One or more eye factors of the patient are determined, a set of different multifocal intraocular lenses having a similar base power are determined based on the eye factors, and a multifocal intraocular lens is selected for the patient from the set based on the eye factors.

Abstract: An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

Abstract: Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include a circular surface structure which acts as a diffractive or phase shifting profile. In some cases, a single ring IOL includes an anterior face and a posterior face, where a profile can be imposed on the anterior or posterior surface or face. The profile can have an inner portion such as a microstructure or central echelette, and an outer portion. Between the inner portion and the outer portion, there may be a transition zone that connects the inner and outer portions.

Abstract: The present invention provides improved ophthalmic lenses and methods for their design and use. Monofocal and multifocal diffractive ophthalmic lenses having reduced light scatter, improved light energy distribution properties, and/or other improvements in optical performance are provided. These properties are provided, at least in part, by the diffractive profiles of the invention, often having subtlety shaped echelettes with appropriately curving profiles. Smooth diffractive profiles may be used reduce light scatter. Diffractive profiles may be configured to limit the light energy in certain selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia. Diffractive profiles of may additionally or alternatively vary the light energy distributed between individual echelettes, providing additional advantages in various viewing situations.

Abstract: An ophthalmic lens for providing a plurality of foci includes an optic having an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens has a first region and a second region. The first region has a first refractive optical power and includes a first base curvature having a finite radius of curvature and a first phase plate having at least one diffraction order with a diffractive optical power.
