21 Method for correcting eye aberration JP2002160256 2002-05-31 JP2003107342A 2003-04-09 ABITBOL MARC
PROBLEM TO BE SOLVED: To provide the design of a spectacle lens for the correction of human vision, including the correction of high order aberrations, and super-normal vision having a remarkably satisfactory function by using spectacles. SOLUTION: Different lenses are described for use at a partial or a fuller field of view. This method applies corrective measures based on data obtained from high order wave front measurements of a subject's eye. According to one method, the Modulation Transfer Function (MTF) of the overall eye and lens optical system is optimized. According to another method, the optimization is performed on the wavefront of the overall eye and lens optical system. Both methods use weighted functions in the optimization procedure. This method of high order aberration correction is also applicable for the design of contact lenses and intra-ocular lenses, and for the execution of refractive eye surgery.

29 Toric intraocular lens with spatially-variant astigmatism US13544593 2012-07-09 US08562131B2 2013-10-22 Huawei Zhao
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.

35 Contact or intraocular lens and method for its preparation US09910491 2001-07-20 US06533416B1 2003-03-18 Bruno Fermigier; Richard Legras; Nicolas Chateau
Toric contact or intraocular lenses having a correcting portion characterized by one or more novel constructions that each produce an optical path that improves angular misalignment tolerance. The lens may be constructed with a “smooth atoric” aspect where the optical path through the correcting portion of the lens corrects for both astigmatism and an axisymmetric aberration other than astigmatism, there being no sudden surface discontinuity between the regions that provide the different corrections (thus, “smooth”). In another embodiment, the lens may be constructed with so-called “sectors” circumferentially arranged around the optical axis such that an optical path through the correcting portion of the lens varies as a function of the angular separation from the reference meridian plane, and the correcting portion is divided into at least two sectors having different astigmatism correction axes. In either embodiment, the correcting surface may be provided on either or both of the anterior or posterior faces of the lens, and the optical performance of the lens in case of angular displacement (the “angular misalignment tolerance”) is increased. Specifically, the angular misalignment tolerance is increased by at least 30% over a standard toric lens of the same class. Definition of the particular shape of the lens enables a mold die of that shape to be formed, or lens machining tools may be used.

38 Aspheric toric lens designs US708362 1996-09-04 US5796462A 1998-08-18 Jeffrey H. Roffman; Edgar V. Menezes
Aspheric toric lens designs are disclosed which reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof. The present invention pertains to ophthalmic lenses, and in particular to contact lenses such as soft hydrogel contact lenses, particularly designed to fit astigmatic patients who are either non-presbyopic or presbyopic. One of the front and back surfaces of the aspheric toric lens defines a spherical surface corresponding at least to the patient's basic distance prescription Rx. The other of the front and back surfaces defines an aspheric toric curve, wherein the toric surface is constructed with aspheric radii, such that the aspheric curve desensitizes axial misalignment of the toric curve by providing an enhanced depth-of-focus. When the aspheric toric surface is on the back surface of the lens, the spherical curve on the front surface of the lens can comprise a single spherical curve corresponding to the patient's basic distance prescription Rx. When the aspheric toric curve is on the front surface of the lens, the spherical curve on the back surface of the lens can comprise a multifocus concentric annular ring spherical surface design.

An ophthalmic lens has front and rear optical surfaces, a central optical axis substantially perpendicular to the lens and comprises a plurality of concentric, contiguous circular refractive bands provided on at least one of the front and rear optical surfaces. The bands have a continuous cross-section in the shape of a segment of an ellipse having a given major axis length and eccentricity. The bands are of alternating optical power to focus light on at least two focal planes to provide simultaneous multifocal vision. The major axis of each ellipse segment intersects the central optical axis and a respective one of the at least two focal planes. The bands are continuous at their boundaries between neighboring ones of the bands. The entire optical surface of the lens may be used with minimal distortion caused by the intersections of the continuous bands.
