摘要： A method for assessing a performance of a laser system for use in corneal ablation is provided that includes directing a beam of laser shots onto a fluorescent indicator. The indicator is adapted to emit a first wavelength of light different from a second wavelength of light impinging thereon. The directing step is performed in a plane of a cornea of an eye desired to be ablated and also onto a cornea positioned at the corneal plane. Light reflected from the indicator is detected, and a difference between a detected light pattern from the camera and a predetermined ablation pattern desired to be made on the cornea is calculated. The predetermined pattern is then corrected to compensate for the calculated difference.

摘要： A system for tracking eye movement includes a detector that is adapted to receive radiation reflected from a retina defining a spatial extent of a pupil of an eye. The detector acts to generate data indicative of a positioning of the received radiation on the detector. A processor is in communication with the detector and has software resident thereon for determining from an analysis of the data a pupil position. A controller is in communication with the processor and with a device for adjusting a direction of radiation emitted by an illumination source responsive to the determined pupil position in order to substantially center the emitted radiation on the pupil. The illumination source is preferably coaxial with the detector, and emits a beam having a diameter less than the pupil diameter.
