  • Patent number: 11460711
    Abstract: Embodiments of the present invention include a backscatter reductant anamorphic beam sampler. The beam sampler can be implemented to measure a power of a reference beam generated by an electromagnetic radiation source in proportion to a power of a working beam. The beam sampler can provide astigmatic correction to a divergence of the working beam along one axis orthogonal to a direction of propagation. The beam sampler can further be implemented to prevent backscatter reentrant radiation from impinging upon a photodetector of the beam sampler resulting in a reduction of error and instability in an assay of the working beam.

  • Patent number: 7404638
    Abstract: A method and apparatus for increasing the depth of focus of the human eye is comprised of a lens body, an optic in the lens body configured to produce light interference, and a pinhole-like optical aperture substantially in the center of the optic. The optic may be configured to produce light scattering or composed of a light reflective material. Alternatively, the optic may increase the depth of focus via a combination of light interference, light scattering, light reflection and/or light absorption. The optic may also be configured as a series of concentric circles, a weave, a pattern of particles, or a pattern of curvatures. One method involves screening a patient for an ophthalmic lens using a pinhole screening device in the lens to increase the patient's depth of focus. Another method comprises surgically implanting a mask in the patient's eye to increase the depth of focus.

  • Patent number: 6830332
    Abstract: According to the invention the ophthalmic lens further comprises a refractive part comprising at least one surface, which is configured to compensate a passing wavefront at least partly for at least one type of monochromatic aberration introduced by at least one of the optical parts of the eye. Said diffractive part is capable of compensating a passing wavefront at least partly for chromatic aberration introduced by at least one of the optical parts of the eye. Furthermore said refractive and diffractive parts together contribute to a required power of the lens.

  • Patent number: 6800091
    Abstract: This patent represents a deformable artificial intraocular lens and method for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. The method of correcting a loss of accommodation includes removing the natural crystalline lens from the eye and inserting an intraocular lens in the eye. This lens represents a breakthrough in removal of mass from the lens. After insertion into the eye, the ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient.

  • Patent number: 6656222
    Abstract: An IOL implantable in an eye comprising an optic having an optical portion for directing light toward the retina of the eye and a cell barrier portion for inhibiting cell growth from the eye in front of or in back of the optical portion. The cell barrier portion circumscribes the optical portion, is incapable of focusing light on the retina and includes an irregularly configured structure, for example, irregular grooves. At least one elongated fixation member is coupled to the optic for use in fixing the optic in the eye.

  • Publication number: 20030199976
    Abstract: A narrow profile, glare reducing, posterior chamber intraocular lens comprises an optic having an anterior surface and a posterior surface and an optical axis. The posterior surface is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power. A transition zone between the two imaging zones preferably has a surface of continuous curvature shaped to reduce direct glare from light incident on the transition zone in an individual's eye in which the intraocular lens is implanted by internal reflection of direct light incident on the transition zone. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye. In variations, the transition zones are formed at the optic edge to minimize direct and indirect in the eye of an individual wearing the intraocular lens.

  • Publication number: 20030078655
    Abstract: A deformable, artificial intraocular contact lens for implantation into the human eye to correct normal-vision problems. The lens may be positioned posteriorly from the iris, resting against the anterior surface of the posterior capsule's natural lens. Alternatively, the lens may be positioned in the anterior chamber of the eye. The implanted lens works in conjunction with the cornea and natural lens to provide proper vision, as a substitute for regular contact lens, spectacles, and radial keratotomy. The lens may be designed from a rigid or semi-rigid material. Due to the thinness of the structure, the lens may be rolled and inserted into the eye, minimizing both the length of the corneal incision and the stretching of the cornea.
