Abstract: An apparatus and method are provided for performing ocular laser surgery using a patient interface having a posterior contact surface that may include surface irregularities that were generated during manufacturing of the patient interface. A beam delivery system having a focusing lens, scanning subsystem and adaptive optic (e.g. deformable mirror) is provided for guiding the surgical laser beam through the patient interface and to a desired focal spot location. An optical detector generates image data representing the posterior patient interface surface which is then processed by a computer system to identify surface irregularities by comparing the image data to a reference surface or axis. In particular, a surface irregularity can be identified as having a z-axis component; a tilt component and a surface profile component. Each irregularity component can be compensated separately by sending an adjustment signal to one of the beam delivery system components.

Abstract: A timing device that includes an anode layer, a cathode layer and an electrolyte attached to a base layer. The anode layer and the cathode layer are placed adjacent to one another along an axis of the timing device. Upon activation of the timing device the anode layer is depleted away from the cathode layer until the timing device is fully expired. Once the timing device is expired, a change is seen indicating that the timing device has expired. In some embodiments, a color change indicates that the timing device has expired. In some embodiments, as the timing device expires electronically readable information is uncovered.

Abstract: In accordance with the present invention, a system and method are provided for controlling postoperative shrinkage of the capsular bag, after the lens has been removed from the capsular bag. The purpose is to establish a proper optical alignment for a prosthetic Intraocular Lens (IOL). Included in the system are a laser unit for generating a laser beam, a detector for creating an image of the prosthetic IOL in the capsular bag, and a computer for evaluating the image to determine an alignment difference between the IOL axis and a defined axis of the eye. The computer is also used for guiding the laser beam to alter selected tissue in the eye, to thereby influence postoperative shrinkage of the capsular bag and minimize any potential alignment difference between the IOL axis and the defined axis of the eye during capsular bag shrinkage.
