AL-VIEW Optical Biometer
Mode Number: AL-VIEW, AL-VIEW LITE
Item Name: Optical Biometer
Features:
This biometer obtains measurements of corneal curvature, lens thickness, astigmatic axis, axial length, central corneal thickness, anterior chamber depth, white-to-white distance, and pupil diameter in just one measurement. It features automatic alignment and focusing for ease of use, and comes standard with eight IOL calculation formulas for immediate processing of measurements.
AL-VIEW LITE, without IOL calculation function.
