2nd hand ophtahlmometrie
That by BLOCK developed (patented) keratometer „RUBIN“ combines the modern computer controlled recording of measured values with the classical, distance independent coincidence principle.
The software, in connection with the microprocessor, allows the indication of the radiuses and the astigmatic difference on an LCD-module with background illumination. The chip further converts radiuses into dioptrines. The exact determination of sagittal radiuses at 25° and 30° are achieved by program-technically controlled setting marks, and both, the values of the sagittal radiuses and the eccentricity are indicated.
When measuring color edge free, reliable cross-test-marks are applied. Using a unique illumination by the especially pretreated halogen lights exact measuring, at minimal dazzling of the eye being subject of measuring even at regular room light, is possible.
Further, RUBIN allows a problem free measuring of soft contact lenses in fluids. The radiuses arc indicated directly, without any need of conversions, on the background illuminated LCD-module.
