<p>A wavefront sensor for measuring ocular aberrations includes a calibration test component (32) and comparative calibration measurement information stored in the device to insure that the device is properly calibrated for reliable aberration measurement. Wavefront calibration, focusing calibration, and retinal illumination level monitoring are contemplated calibration measurements. An optional interlock function prevents diagnostic/therapeutic operation of the aberrometer if it is out of calibration or unsafe for use. A method for calibrating an aberrometer is described.</p> |
