background
Auto-Refractometer / Keratometer optometry equipment provide fast, accurate and precise measurements
during eye examination to provide an objective measurement of a person's refractive error
The Keratometry measuring Mode is integrated to measure the radius of curvature of the corneal anterior surface,
particularly for assessing the extent and axis of astigmatism.

*Retro-illumination

Retro-illumination
Retro-illumination is another form of indirect viewing, where the light is reflected off the deeper structures,
such as the iris or retina. This method is useful for examining the size and density of opacities,
but not their location. Retro-illumination is available at ARK-9910 Auto Refractometer / Keratometer.
