摘要： A system for providing vision contains an aberrometer, a wavefront sensor, and a transfer optical system. The aberrometer is configured to measure a received wavefront. The aberrometer includes a wavefront sensor and a transfer optical system for transferring an input wavefront so as to the provide the received wavefront at or near the wavefront sensor. The system also includes a processor in communication with the aberrometer, a readable memory, and instructions located within the memory. The readable memory contains one or more system error parameters and instructions available to the processor. The instructions are for determining at least one aberration of the received wavefront and calculating the input wavefront based on the received wavefront and the one or more system error parameters.

摘要： A shielded superconducting MRI magnet system uses a multi-layer shielded coil design. By splitting the magnet coils into a plurality of coil layers, an increased number of degrees of freedom is achieved which, in turn, permits minimization of the overall length of the magnet while nevertheless avoiding excessive magnet field and stress values in the coils. A compact coil system is thereby designed which also satisfies the plurality of MRI requirements with regard to sufficiently large investigational volume, magnet field strength, acceptable homogeneity, and magnet stray field limitation while achieving sufficiently low maximum coil B field strengths and stress values to avoid quenches and maintain the structural integrity of the magnet.

摘要： An intraocular lens for correcting or reducing the astigmatism of a cornea includes an optical element that has optical properties and characteristics that make it tolerant of rotational misalignment, when compared to a comparable lens having a uniform astigmatism orientation across its entire optical element, leading to more relaxed tolerances for a surgeon that implants the lens. The optical element of the toric ophthalmic lens has meridians associated therewith, including a high power meridian and a low power meridian orthogonal to the high power meridian. The optical element has at least one radially modulated meridian along which power monotonically varies with increasing radial position.

摘要： An intraocular lens for providing vision to an animal or human subject has anterior and posterior sides. The lens includes an optic body, one or more haptics, and one or more marks. 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.

摘要： 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.

摘要： 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.
