摘要:
In various embodiments, high-viscosity fluids are utilized to fill implantable reservoirs while filling accuracy is improved via elimination of dead space and/or utilization of pushing fluids to urge the high-viscosity fluid into the implantable reservoir.
摘要:
In various embodiments, an intraocular lens features multiple compartments that, depending on the angular position of the lens, present different combinations of fluids to the central optical region of the lens to alter the refractive power of the lens.
摘要:
The lens geometry and power of an intraocular lens is optimized to provide both distance and near vision correction for a patient. The optimization may be based on one or more measured accommodation-related parameters and one or more estimated accommodation-related parameters. An accommodative amplitude may be predicted based on the measured and estimated accommodation-related parameters, and the optimized the intraocular lens geometry and power established based thereon.
摘要:
In various embodiments, ocular treatment systems, intraocular lenses, and treatment methods are utilized for the treatment or prevention of posterior capsule opacification of the eye by, for example, targeting portions of the posterior lens capsule for ablation while minimizing damage to implanted intraocular lenses.
摘要:
An implantable intraocular lens and methods of manufacturing them provide a target degree of optical accommodation. In various embodiments, the lens includes at least one internal optic, an outer shell for enclosing at least a portion of the internal optic, and a fluid at least partially filling the outer shell.
摘要:
Monochromatic or multichromatic images may be created on surfaces. The surface is moved to first, second and third stations. The surface is electrically biased, and powder is transferred to the surface electrostatically at the first station. The powder is fused or sintered selectively on the surface at the second station. Unfused or unsintered portions of the powder are removed from the surface at the third station.
摘要:
A method for preparing a sample by utilizing a mechanical force in the presence of a size stabilizer to break apart the sample to obtain nucleic acid molecules in a usable size range.
摘要:
Implantable reservoir structures include an interior and/or exterior modifying element joined to the interior and/or exterior surface of the membrane defining the reservoir in order to alter one or more physical properties thereof. The physical properties can be mechanical (e.g., material strength, flexibility, shear modulus, Young's modulus, hardness, and/or ductility); optical (e.g., refraction, transparency, transmission spectrum, absorption spectrum, fluorescence spectrum, and/or color); and/or permeability to liquids generally or to a particular type of liquid, solute, or suspended material.
摘要:
Embodiments of intraocular lenses described herein include features that enhance depth of focus and/or reduce chromatic aberration. These features may include different optical fluids, multiplexed or asymmetric lens arrangement, dispersive or diffusive elements, and others.
摘要:
In various embodiments, implants including reservoirs, such as intraocular lenses, feature flexible membranes and valves integrated therewith, the valves having apertures that are normally closed.
