Abstract: The present invention provides methods, systems and software for scaling optical aberration measurements of optical systems. In one embodiment, the present invention provides a method of reconstructing optical tissues of an eye. The method comprises transmitting an image through the optical tissues of the eye. Aberration data from the transmitted image is measured across the optical tissues of the eye at a first plane. A conversion algorithm is applied to the data, converting it to corrective optical power data that can be used as a basis for constructing a treatment for the eye at a second plane.

Abstract: An intraocular lens for insertion into a capsular bag in order to focus incoming light toward a retina and process for manufacturing thereof along with concomitant reduced glare and improved vision provides for a center lens portion of a lens for focusing incoming light toward the retina and the surrounding lens portion for mounting the lens within the capsular bag. A surface roughness disposed on the surrounding lens portion is provided for reducing the glare due to non-focused light directed toward the retina from the intraocular lens with the roughness having a roughness level of between about Ra 45 and about Ra 350.

Abstract: An ophthalmic lens for modifying or reducing non-axisymmetric higher order aberrations includes an optic body disposed about an optical axis having a primary meridian and an orthogonal secondary meridian. The optic body comprises an anterior surface and an opposing posterior surface. The optic body includes an optic zone comprising a base shape that is configured to form an image or focus from light incident on the surfaces, either alone or when used within an optical system. The optic body also includes a higher order toric shape that is imposed on or added to one of the surfaces. The higher order toric shape also includes a first profile disposed along the primary meridian and a second profile disposed along the secondary meridian that is different in shape from the first profile. The higher order toric shape is characterized by a profile along at least one meridian of the lens that changes with increasing radius from the optical axis raised to a power that is greater than two.

Abstract: An intraocular lens for correcting or reducing the astigmatism of a cornea includes a pupil that is spatially divided into discrete zones, with each zone having a particular astigmatism magnitude and astigmatism orientation. In one embodiment, the zones all have the same astigmatism magnitude, which is equal and opposite the cornea astigmatism magnitude to within a particular tolerance, such as 0.25 diopters. In one embodiment, some or all of the zones all have different astigmatism orientations, with the angular separation between astigmatism orientations being on the order of the rotational misalignment tolerance of the lens to the cornea. The visual performance of such a lens deteriorates more slowly with rotational misalignment, when compared to a comparable lens having a uniform astigmatism orientation across its entire pupil, leading to more relaxed tolerances for a surgeon that implants the lens.

The method, system and apparatus include a toric intraocular element for correcting astigmatism and having a cylinder power, and a depth of focus extender coupled to the toric intraocular element, the depth of focus extender extending a depth of focus. The extended depth of focus may reduce sensitivity of the toric intraocular element to at least one of rotation and selected cylinder power.

Each mark has four or more features disposed along an imaginary line when viewed from the anterior side and/or the posterior side. The mark(s) may be used as an aid in angularly aligning the lens during use.

At least a portion of the outer region has a curvature that varies with distance from the optical axis.
