Peripheral refraction
Webreadings, the device provides the peripheral (ø 6 mm) cornea simultaneously. KAI (Kerato-Asymmetry Index) and KRI (Kerato-Regularity Index) display irregularities of the cornea. Accurate starting values for subjective refraction are essential. The high-speed mode allows accurate results to be obtained – even in uncooperative patients.
