摘要： A slit lamp for illuminating an eye comprises several LEDs electrically coupled to an LED driver. A user input accepts input for a length, a width and an intensity of a shaped beam of light. An LED driver selectively drives a set of LEDs of an LED array to form a shaped light beam having a desired size across a beam cross-section. In some embodiments, several optical fibers at a first end of a fiber optic manifold are optically coupled to LEDs of an LED array, and an optic is placed near a second end of a fiber optic manifold. Several ends of optical fibers of the fiber optic manifold are optically coupled to the set of selectively driven LEDs, and are arranged so as to form the shaped light beam having a desired size across the beam cross-section.

摘要： The present invention provides methods, systems, and apparatus for calibrating a laser ablation system, such as an excimer laser system for selectively ablating a cornea of a patient's eye. The invention also facilitates alignment of eye tracking cameras that measure a position of the eye during laser eye surgery. A calibration and alignment fixture for a scanning laser beam delivery system having eye tracking cameras may include a structure positionable in a treatment plane. The structure having a feature directing laser energy incident thereon to a calibration energy sensor, at least one reference-edge to determine a characteristic of the laser beam (shape, dimensions, etc.), and an artificial pupil to determine alignment of the eye tracking cameras with the laser system.

摘要： Devices, systems, and methods for treating and/or determining appropriate prescriptions for one or both eyes of a patient are particularly well-suited for addressing presbyopia, often in combination with concurrent treatments of other vision defects. High-order spherical aberration may be imposed in one or both of a patient's eyes, often as a controlled amount of negative spherical aberration extending across a pupil. A desired presbyopia-mitigating quantity of high-order spherical aberration may be defined by one or more spherical Zernike coefficients, which may be combined with Zernike coefficients generated from a wavefront aberrometer. The resulting prescription can be imposed using refractive surgical techniques such as laser eye surgery, using intraocular lenses and other implanted structures, using contact lenses, using temporary or permanent corneal reshaping techniques, and/or the like.

摘要： An eye measurement system may include a target that moves transverse to an optical path from the target to eye, so as to relax accommodation of the lens of the eye. The target may move transverse to the optical path on a display. The patient may be fogged while the target moves transverse to the optical path, and the target may become smaller such that the patient perceives the target to be moving away from the patient. A pupil camera may measure eye position that can be correlated with the position of the target on the display to determine that the patient has maintained fixation on the moving target. A visible measurement light beam may be pulsed subsequent to and/or during motion of the target that relaxes accommodation of the eye so as to avoid visual interference of the measurement light beam with the target on the display.

摘要： Devices, systems, and methods often by measuring characterize optical structures and systems, the standard refractive error and irregular aberrations. A retinal spot can propagate through optical tissues of an eye and can be directed to refractive correction optics for correcting standard refractive errors. The corrected image is then directed to wavefront analysis optics, which form a coarse pitch lenslet array pattern and a fine pitch lenslet array pattern. The coarse pitch pattern indicates the standard refractive error of the eye, and can be used to adjust the refractive correction optics. The fine pitch pattern is formed with the corrected retinal image, facilitating precise wavefront reconstruction, measurement of high order aberrations, and the like. The coarse pitch pattern and fine pitch pattern may be formed sequentially or simultaneously.
