tracey1

 

 

As the name indicates, this device investigates the optical aberration of the eye in general and corneal aberration alone, with single ray tracing method. Contrary to other devices in this method, only one ray of light is projected into the eye in each turn, and the reflected ray is detected.

Eventually, the device analyzes the information obtained. By eliminating the interference effect of the optical rays on each other, this method leads to higher analysis accuracy.
