Refractometer

The automatic 3D alignment function conserves the appropriate alignment with the patient. 
The automatic 3D alignment conserves the XYZ alignment even during the small moves of the eyes, providing continuous and repeated measurements. The user follows the alignment direction on the screen for initial alignment and eventually the alignment and measurement start automatically. The automatic 3D alignment function supports the easy function. 

Unlimited accuracy
The unique Rotary Prism technology, exclusively for Topcon, allows uncomparable accuracy and reliability. This system measures a wider area in the retina, while allowing measurement through through even a small pupil of up to 2mm diameter.
