摘要： A system (200) or method of positioning an ophthalmic device relative to an eye is provided. The method first obtains a series of images of an eye. In these series of images, the distance between the ophthalmic device and the eye is varied while the region of the eye image remains substantially the same. It is possible then to process these images to determine the high frequency content associated with each image. By comparing the high frequency content associated with each image, it is possible to determine which image has the largest amount of high frequency content. The high frequency content is maximized when the image is the sharpest. An optimally focused image will have the largest amount of high frequency content . By examining the high frequency content associate with the series of images is impossible to adjust the relative position and distance between the eye and the ophthalmic device to the distance associated with the image having the largest amount of high frequency content (i.e., optimally focused) .

摘要： A method for assessing a performance of a laser system (11) for use in corneal ablation is provided that includes directing (101) a beam (13) of laser (14) shots onto a fluorescent indicator (12). 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 (18) of a cornea (21) of an eye desired to be ablated and also onto a cornea positioned at the corneal plane. Light reflected (20) from the indicator is detected (102) using a camera (22), 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 (107). The predetermined pattern is then corrected (108) to compensate for the calculated difference.

摘要： A method for assessing a performance of an ablation laser system is provided including ablating (102) a substrate surface (13) to achieve a predetermined ablation pattern. A beam of light is directed (103) across the ablated substrate, and reflected light is received to detect an actual ablated pattern, which is compared (104) with the predetermined ablation pattern. The resulting comparison is displayed (105) to a user so that the performance of the laser system can be assessed. A system (10) includes a support (12) that is adapted to hold an ablation substrate (13) at a treatment plane. An optical scanner (19) directs a beam of light (20) across the ablated substrate (13) and receives light (21) reflected therefrom to detect an ablated pattern. An analyzer (22) compares the detected ablated pattern with the predetermined ablation pattern. A display (24) in signal communication with the analyzer displays a comparison of the detected ablated pattern and the predetermined ablation pattern.

摘要： An optical wavefront sensing system (10,30) includes a lenslet array (11,31) positioned for receiving an incoming wavefront (12,32). Downstream of the lenslet array is positioned an image transformer (16,36), which transforms the image emerging from the lenslet array at a focal plane (20,40) thereof into a real image. A sensor (22,42) is positioned at a final image plane (21,41) for sensing the transformed image. This sensor may comprise, but not intended to be limited to, a charge-coupled-device (CCD) camera. The method for sensing an optical wavefront includes the steps of receiving an incoming wavefront using a lenslet array and transforming an image emerging from the lenslet array at a focal plane thereof into a real image. The transformed image positioned at a final image plane is then sensed, and, in a preferred embodiment, analyzed to determine wavefront distortions.

摘要： A calibration device (10,30) for an aberroscope is provided which includes an optical element (40,50) that is insertable into an optical path of a wavefront analyzer. The optical element is adapted to induce a predetermined aberration in a wavefront. The optical element, which may be transmissive or reflective, may comprise a lens optimized for a specific power and aberration; a computer-generated hologram; or a spatial light modulator. A substantially unaberrated wavefront (35) is passed along an optical path leading to a wavefront analyzer. A predetermined aberration is induced in the unaberrated wavefront to form an aberrated wavefront (37,37') using an optical element positioned in the optical path. The aberrated wavefront is then analyzed using the wavefront analyzer, which is calibrated using data generated by the wavefront analyzer from the aberrated wavefront.

摘要： A light-translation system (10) includes a fixed base (15,16) and translatable mirror mount (23,24) having mirror-supporting brackets (110,114). A first and second arm (27,28) are pivotally attached in parallel, spaced-apart relation adjacent first ends to the base and adjacent second ends to the mirror mount to form a parallelogram-shaped attachment with the base and mirror mount. The pivotal attachments are formed using flexural pivots (63), each having a thick portion (64,65) oriented for achieving minimal angular deviation of the mirror (11). A first bracket (110) has three pads (111,112,113) for supporting one side (104) of the mirror. A second bracket (114) has two surfaces (115,116) shaped to support an edge (109) of the mirror, each surface positioned opposite a pad. A washer (119) dimensioned to admit a mounting screw (117) is positionable opposite a third pad (113) against an outside wall (118) of the mirror mount to removably retain the mirror without imposing appreciable bending stress thereon.

摘要： A method for optimizing a prescription for laser-ablation corneal treatment includes receiving a measured correction prescription for a current patient. Next a database of treatment outcomes on a plurality of previously treated patients is accessed. The database contains a desired correction, and an actual correction. A difference between the desired correction and the actual correction represents an over- or undercorrection resulting from surgery. From the difference data is calculated a distribution of data points as a function of correction level. From the data-point distribution is calculated a statistically based offset applicable to the correction prescription for matching actual corrections with desired corrections. From the data-point distribution is calculated a confidence interval of the data using a predetermined confidence level. The statistically based offset is then adjusted based upon the confidence interval to provide an optimized prescription. The adjusted offset is then output for use in performing a refractive procedure.

摘要： An illumination system (301) and method of illuminating a surgical site are disclosed. One embodiment of the illumination system comprises: a composite illumination source (302), comprising a plurality of light sources operable to emit a plurality of collinear light beams (310); and an illumination lens (304), operable to receive and focus the plurality of light beams at a focal plane; wherein the plurality of collinear light beams are directed onto an off-axis portion (306) of the illumination lens and wherein the illumination lens is aligned co-axially and confocally with an objective lens (305) of an observation device. The light sources can be solid-state lighting devices, such as light-emitting diodes. The observation device can be a surgical ophthalmic microscope. The illumination lens can have a larger diameter than the objective lens, and the off-axis portion of the illumination lens can comprise a Fresnel type lens. The illumination lens can have a clear central portion (307) of a diameter sufficient to prevent interference with the focusing function of the objective lens, or the illumination lens can comprise a ring with a central opening of a diameter sufficient to prevent interference with the focusing function of the objective lens (305).

摘要： Deinterlacing is applied to a composite video image that includes alternating even and odd rows of pixels. The even rows form a first image; the odd rows, a second image; these are recorded at different times, introducing a possibility of motion artifact. A first average horizontal intensity difference is computed (105) between the first image and the second image. The first image is offset (106) by one pixel in each horizontal direction to form a horizontally offset image, and another average horizontal intensity difference is computed (107). A minimum average intensity difference is determined (110) from a comparison of the average horizontal intensity differences. The first image is shifted (113) in a horizontal direction determined to achieve the minimum average horizontal intensity difference, and the horizontally shifted first image is combined (114) with the second image to form an imiproved composite image. An analogous series of steps is carried out in a vertical direction.
