摘要： A method and system are provided for sensing eye motion, such as saccadic eye motion, in a non-intrusive fashion. An optical delivery arrangement converts a laser beam pulse into a plurality of light spots. The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary whose movement is coincident with that of eye motion. 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 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.

摘要： A surface treatment laser beam delivery and tracking system is provided. The laser generates laser light along a original beam path at an energy level suitable for treating (e.g., eroding) a surface. An optical translator shifts the original beam path onto a resulting beam path. An optical angle adjuster changes the angle of the resulting beam path relative to the original beam path such that the laser light is incident on, and spatially distributed, the surface to be treated. A motion sensor transmits light energy to the surface and receives reflected light energy from the surface via the optical angle adjuster. The light energy transmitted by the motion sensor travels on a path that is parallel to the shifted beam as they travel through the optical angle adjuster. The reflected light energy is used by the motion sensor to detect movement of the surface relative to the original beam path and generate error control signals indicative of the movement. The optical angle adjuster is responsive to the error control signals to change the angle of the resulting beam path and the angle of the motion sensor's light energy in correspondence with one another. In this way, the beam originating from the treatment laser and the light energy originating from the motion sensor track together with the surface movement.

摘要： Vision in an eye is corrected using an energy source for generating a beam of optical radiation and focusing optics disposed in the path of the beam for directing the beam through the eye, where the beam is reflected back from the retina of the eye as a wavefront of radiation to be measured. An optical correction based on an optical path difference between the measured wavefront and a desired plane wave, and refractive indices of the media through which the wavefront passes is provided to a laser delivery system with a laser beam sufficient for ablating corneal material from the cornea of the eye. The laser beam is directed at selected locations on the cornea for ablating the corneal material in response to the optical correction to cause the measured wavefront to approximate the desired plane wave, and thus provide an optical correction.

摘要： A system is provided for use with an ophthalmic treatment laser that produces a treatment laser beam. The system automatically inhibits transmission of the treatment laser beam when a threshold amount of eye movement is detected. An eye movement sensor determines measurable amounts of eye movement such as saccadic eye movement. The eye movement sensor generates light energy that is eye safe, focuses the light energy on the eye, and detects energy reflected from the eye due to the incident light energy. The eye movement sensor determines the measurable amount of eye movement based on changes in the reflected energy. A dichroic beamsplitter is optically disposed between the ophthalmic treatment laser and the eye to direct the treatment laser beam to the eye. The beamsplitter is also optically disposed between the eye movement sensor and the eye to direct the sensor's light energy to the eye and the resulting reflected energy back to the sensor. When the measurable amount of eye movement exceeds the threshold amount, control logic outputs a treatment laser inhibit signal to the ophthalmic treatment laser.
