Embodiments of light-based enhancing apparatuses and methods of use are described. In one embodiment, the light based-enhancing apparatus may comprise a toothbrush that includes a light source, a head with a plurality of bristles (and/or other materials that may be used to brush a tooth such as, e.g., a sponge, plastic prongs or resilient massaging rods/tips) and a window so that light emitted from the light source can pass through the window. In another embodiment, the light-based enhancing apparatus may comprise a razor or an electric razor that has a head with at least one blade and a light source that is adapted for emitting light proximal to the head of the razor.

An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an 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 a haptic portion to 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. Displacement of fluid to the actuator may either increase or reduce the degree of deflection imposed on the lens element by the actuator.
摘要:
An accommodating intraocular lens is provided, in which optical parameters are altered in-situ using forces applied by the ciliary muscles, and in which a lens body carries an actuator separating two fluid-filled chambers having either the same index of diffraction or different indices of refraction. The actuator causes the relative volumes of fluid within an optic element of the lens to change, thereby altering the optical power of the lens.

摘要:
Fiber delivered laser pulses emulsify thrombus by mechanical stresses that include a combination of pressure, tension and shear stress. Laser radiation is delivered to the locality of a thrombus and the radiation is absorbed by blood, blood dot, or other present materials. The combination of a leading pressure wave and subsequent vapor bubble cause efficient, emulsification of thrombus. Operating the laser in a low average power mode alleviates potential thermal complications. The laser is operated in a high repetition rate mode to take advantage of ultrasound frequency effects of thrombus dissolution as well as to decrease the total procedure time. Specific parameter ranges for operation are described. The device includes optical fibers surrounding a lumen intended for flow of a cooling agent. The fibers may be arranged concentrically around the lumen to deliver radiation and heat over as large an area as possible. An alternative design approach incorporates the optical fibers into the wall of the guiding catheter and utilizes the catheter lumen as the cooling channel. An eccentric tip enables rotation of the device to address all parts of the vasculature. The eccentricity can be provided via a variety of means: spring dip, balloon, protrusion, etc.
摘要:
An accommodating intraocular lens is provided in which a deflectable lens element is anchored to a substrate along its optical axis to define a fluid filled space. Fluid-filled haptics disposed in fluid communication with the space vary the fluid volume in the space responsive to forces applied by the ciliary muscles, thereby causing the periphery of the lens element to deflect relative to the substrate and changing the optical power of the intraocular lens.
