Accommodating intraocular lenses and methods of use

A bidirectional gas discharge tube (GDT) includes a discharge chamber, first and second cathodes, a gas disposed within the discharge chamber, and a control grid. The first and second cathodes are disposed within the discharge chamber and include first and second faces, respectively. The first face and the second face are plane-parallel. The gas is configured to insulate the first cathode from the second cathode. The control grid is disposed between the first and second cathodes within the discharge chamber. The control grid is configured to generate an electric field to initiate establishment of a conductive plasma between the first and second cathodes to close a conduction path extending between the first and second cathodes.

Bidirectional gas discharge tube

A DC circuit breaker includes a gas discharge tube (GDT) coupled in parallel with an extinguishing path. The GDT conducts and interrupts a load current through a normal current path. The GDT includes a thermionic cathode, an anode, and a control grid. The control grid is configured to regulate opening and closing of the normal current path. The extinguishing path is configured to lengthen a break time for the DC circuit breaker.

A cold-cathode switching device is presented. The cold-cathode switching device includes a housing defining a chamber; an ionizable gas disposed in the chamber; and a plurality of electrodes disposed in the chamber. The plurality of electrodes includes a cathode and an anode defining a discharge gap, and wherein at least one of the cathode and anode comprises a material that is liquid at an operating temperature of the cathode or the anode.

Accommodating intraocular lenses

An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

A gas switch includes an anode and a cathode spaced apart from the anode, wherein the cathode includes a conduction surface. The gas switch also includes a plurality of magnets arranged to generate a magnetic field that defines an annular path over a portion of the conduction surface at a radial distance from a switch axis, and a control grid positioned between the anode and the cathode. In operation, the control grid is arranged to establish a conducting plasma between the anode and the cathode, wherein, in the presence of the conducting plasma, a voltage drop between the anode and the cathode is less than 150 volts, and wherein the conducting plasma forms a cathode spot that circles the annular path.

Low voltage drop, cross-field, gas switch and method of operation

Methods of adjusting an intraocular lens after implantation. In some embodiments the methods include positioning an accommodating intraocular lens within an eye, the intraocular lens comprising an optic portion in fluid communication with a peripheral chamber, wherein movement of a fluid between the peripheral chamber and the optic portion in response to ciliary muscle movement changes the optical power of the lens, and reducing a power of the intraocular lens by causing the fluid to move between the optic portion and the peripheral chamber, wherein the reduction in power of the intraocular lens is not in response to ciliary muscle movement, and wherein the positioning step occurs prior to reducing the power.
