OPERATION PRINCIPLE
Refraction (REF)
The instrument projects a near infra red ring of light onto the retina and the reflection of the ring is cap-
tured by a CCD camera. An internal computer analyzes the image and calculates the spherical, cylin-
drical and axial values.
Keratometry (KRT)
The instrument projects a near infra red ring of light onto the cornea and the reflection of the ring is
captured by a CCD camera. An internal computer analyzes the image and calculates the curvature
radius, corneal astigmatic axis and the corneal refractive values.
