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:
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.

摘要:
Peripheral surgical systems are used for insertion and filling of fluid-filled intraocular lenses, reaccessing and modifying fluid-filled intraocular lenses, and explantation of lenses. Although one peripheral surgical unit may perform all of these functions, in some embodiments different units perform different functions—i.e., each function may be performed by a separate unit, or the functions may be distributed over a smaller number of functional units.

Embodiments of method of manufacturing an implantable pump, including providing an upper layer comprising a dome structure for housing a drug chamber and a cannula in fluid communication with the drug chamber, providing a middle deflection layer adjacent the drug chamber, providing a bottom layer comprising electrolysis electrodes, and bonding the upper layer, middle deflection layer, and bottom layer to form the pump.
摘要:
A variable capacitor, a microfabricated implantable pressure sensor including a variable capacitor and an inductor, and related pressure measurement and implantation methods. The inductor may have a fixed or variable inductance. A variable capacitor and pressure sensors include a flexible member that is disposed on a substrate and defines a chamber. Capacitor elements extend indirectly from the flexible member. Sufficient fluidic pressure applied to an exterior surface of the flexible member causes the flexible member to move or deform, thus causing the capacitance and/or inductance to change. Resulting changes in resonant frequency or impedance can be detected to determine pressure, e.g., intraocular pressure.
