Well-known from:• RC-5000• RT-7000 • EM-3000• FT-1000• SS-1000 CASIA

Now on a new basis;touch screen operated, more measurements in less time than the competitors

IOL Calculation With Gaussian Optics Formulae

OA-2000 is prepared for: • Contact • Immersion• Optical

By reducing our potential we can simulate theIOL-master in order to use ULIB data


Every mode needs an own A-constant

Why to cut our potential? Courage for precision!

Real topography for IOL calculation by ray tracing: OKULIX and EASY IOL

• All eye types become „normal“ • IOL calculation becomes fast and easy

even after refractive surgery ...

As soon as a cornea is asymmetric, a keratometer will be insufficient! Only solution: topography

Measuring of pupil and cornea diameter (W-to-W) by means of video analysis

--- Pupil diameter: important for calculating the best focus with OKULIX--- White to White is used in ICL calculation.

Post-OP IOL position is critical in short eyes.

Solution:EASY IOL and OKULIX for precise prediction of post-OP IOL position

ACD and LT are essential for better IOL calculation!
