This optical biometric instrument is used for the measurement of the optic axis and the calculation for correct IOL readings with full accuracy. The fast measurement speed and non-contact are intended for patient comfortability. Capturing 8 different measurements in less than 5 seconds which are corneal thickness, anterior chamber depth, lens thickness, axial length, corneal curvature, axial angle, white to white distance measurement (corneal diameter), and pupil diameter.
