Abstract: A surface treatment laser beam delivery and tracking system. The laser (500) generates laser light (502) along a path at an energy level suitable for treating a surface. An optical translator (520) shifts the path onto a resulting beam path. An optical angle adjuster (310, 316, 320, 326) changes the angle of the resulting beam path relative to the original path such that the laser light is incident on the surface to be treated. A motion sensor (100) transmits light energy (101-T) to the surface and receives reflected light energy (101-R) from the surface via the optical angle adjuster. The light energy travels on a parallel path to the shifted beam through the optical angle adjuster. The motion sensor detects movement of the surface relative to the original path and generates error control signals indicative of the movement. The optical angle adjuster responds to the error control signals to change the angle of the resulting beam path.

Abstract: A system and method for objective measurement and correction of focusing optical systems comprising optics disposed in the path of the beam (18) which directs the beam through the focusing optical system, e.g., and eye (120) and focuses the beam at its rear portion (122). The beam is diffusely reflected back and a wavefront analyzer (26) is disposed in the path of the wavefront projected from the optics and calculates the distortions as an estimate of aberrations of the focusing optical system.

Abstract: A method and system are provided for sensing eye motion, such as saccadic eye motion, in a non-intrusive fashion. An optical delivery arrangement (105) converts a laser beam pulse (104) into a plurality of light spots (21-24). The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary (12) whose motion is coincident with that of eye movement. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement (156) detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye motion.

Abstract: A method and system are provided for eroding or ablating a shaped volume of an eye's corneal tissue (10) in accordance with the treatment of a specified eye condition. To determine the laser beam shot pattern, a plurality of laser beam shots of uniform intensity are first selected to form a uniform shot pattern of uniform shot density. The laser beam shots applied in accordance with the uniform shot pattern of uniform shot density would be capable of eroding a volume of the corneal tissue (10) of uniform height. The volume of uniform height is approximately equivalent to that of the shaped volume. The laser beam shots are applied to the corneal tissue in a spatially distributed pattern spread over an area approximately equivalent to the surface area of the shaped volume to be eroded. The spatially distributed pattern extends the uniform shot pattern in fixed angles from a reference position on the shaped volume representative of the shaped volume's axis of symmetry. Shot density for the laser beam shots changes in correspondence with distance from the reference position.
