Daifs corneal visual center (cvc) localizer (locator) is a point light source of infra red (ir) light, attached and fixed to any eximer laser machine, located at equal distance and in exactly opposite direction from the middle of a detecting camera that detects ir light reflection from the corneal surface and the pupillary margin of the iris with a point fixation target or its virtual extension, perpendicular to the plan containing the localizer and the middle point the inlet of the detecting camera, exactly in the middle of the distance between the localizing point light source and the middle point the detecting camera. With the localizer in position and activated, the cvc will be seen on the screen of ir eye tracking as a white dot somewhere inside the white circle that represents the detected pupillary margin.

Pull-out device for at least two pull-out furniture parts


A device for blocking the pull-out movement of pull-out furniture parts including, for each of the pull-out furniture parts, a driver, a blocking unit which has a shiftable actuating, and a retraction spring and blocking rods which cooperate with the actuating parts, a respective actuating part that is shifted due to movement of the driver when the pull-out furniture part is pulled out and that displaces a blocking rod in a longitudinal axis direction, the blocking rods being blocked from any further axial displacement by a stop. Each of the blocking units has a pivotable catch arm that swivelable about a stationary pivot axis lying parallel to the longitudinal axes of the blocking rods and is loaded by the refraction spring, the catch arm being pivoted by the driver from an initial position to a final position when the pull-out furniture part is pulled out, thereby shifting the actuating part..

Methods and devices for refractive correction of eyes


Methods and devices are provided to obtain refractive correction with superior visual acuity (e.g., 20/10) by achieving an astigmatism-free customized refractive correction. The astigmatism-free customized refractive correction involves obtaining an objective and precise measurement of cylindrical power in a resolution between 0.01 d and 0.10 d in an eye using an objective aberrometer, reliably relating the cylindrical axis obtained from the objective aberrometer to that in a phoroptor, determining an optimized focus error of an eye through subjective refraction with a phoroptor, generating a customized refraction by combining the objective measured cylindrical power, the objective measured cylindrical axis, and the subjectively measured focus power, fabricating a custom lens with a tolerance finer than 0.09 d based on the generated customized refraction, and delivering an ophthalmic lens that can provide an astigmatism-free refractive correction for an eye..
