Abstract:
A method for customizing corneal corrections includes superposing an imaginary reference field (grid) on the anterior surface of the cornea of an eye to divide the corneal surface into reference areas. Also, a diagnostically determined refractive power map for the cornea is created. An incising laser beam is then directed through an individual reference area to a focal spot. Next, movement of the focal spot along the laser beam path is selectively accomplished to photoalter a predetermined volume of stromal tissue. Subsequently, based on the refractive power map, the predetermined volume of stromal tissue that is to be photoaltered is identified for each specific reference area. Accordingly, the steps of directing the beam and moving the focal spot are then repeated using selected reference areas until the required corneal correction is achieved.
Method And Apparatus For Oscillator Start-Up Control For Mode-Locked Laser

International Classification:
H01S 3091
US Classification:
372 18, 372 70, 372 75
Abstract:
The invention is directed to an apparatus and method for oscillator start-up control, and more particularly to an apparatus and method for overdriving a laser to obtain mode-lock operation. The oscillator with start-up control has a lasing medium mounted on a base. A laser pumping source is mounted on the base for inducing a laser beam from the lasing medium. A mode-lock detection device is mounted about the base. An overdrive circuit is coupled with the mode-lock detection and signal processing device for determining mode-lock status of the oscillator. The overdrive circuit overdrives the pump source when the oscillator is not in mode-lock status.

International Classification:
A61F009/008
US Classification:
606 4, 128898, 606 5
Abstract:
A method and system for improved material processing using a laser beam. The method and system includes directing a laser beam above, at or below the surface of the material in one or more preferred patterns and with preferred laser pulse characteristics specific to the material to reduce or mitigate the accumulation or effects of gas, debris, fluid, or other by-products of photodisruption either at the location where additional laser pulses are being placed or in other sensitive locations in the material.

International Classification:
G01B 11/00
US Classification:
356399, 356400, 356124
Abstract:
The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.

International Classification:
G06F 19/00
US Classification:
235385, 235375, 606 10
Abstract:
System and method for identifying a component, such as an optical probe or pneumatic scissors, of an ophthalmic surgical device. A component of a surgical device includes an identifier, such as a RFID tag. Data from the RFID tag is transmitted to a RFID reader in the device. A controller determines whether the component corresponding to the received data is operable with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller enables or disables the operation of the device with the component based on whether the criteria is satisfied, the number of uses of the component, an amount of time that has passed since the component has been used, or a geographic location. The RFID data can also be used to calibrate the surgical device for use with the particular component and for inventory and monitoring purposes.

Abstract:
A multifunction surgical footswitch is disclosed, one embodiment of the surgical footswitch comprising: a base assembly, wherein the base assembly comprises a shroud and a heel plate; a stand-by/ready switch attached to the base assembly and operable to provide a stand-by/ready control signal to switch a laser between a stand-by and a ready state; and a firing switch attached to the base assembly and operable to provide a firing control signal to fire the laser. The surgical footswitch can further comprise an interface communicatively coupled to the firing switch and the stand-by/ready switch and operable to communicate the firing and the stand-by/ready control signals to the laser.

Abstract:
Generally speaking, the output brightness of an illuminator is varied by chopping an output light beam such that the beam is alternately interrupted and unhindered. An interrupter can be rapidly moved into and out of the transmission path of a light beam. The brightness of the light beam received at a site will be attenuated based on the amount of time per cycle the light beam remains obstructed versus unhindered.
