Scanning 400 lines over 60° provides high quality images, which are essential for accurate analysis.


Using new algorithms, axial length measurements and IOL power calculations are performed twice as rapidly as the conventional model.


The pachymetry mode offers precise measurement of the corneal thickness within a ±5 μm error. (The model without pachymetry is also available.)

Internal printer

B-scan image is easily printed with the internal thermal printer and can be attached to the patient's medical record sheet.
