Keratometer is based on Hartmann-Shack wavefront sensor, which analyzes many focal spots of a light wavefront
It has the ability to measure not just the basic refraction error of a customer, but to obtain a spatially resolved refraction map
The instrument utilizes a unique wavefront analysis algorithm and surpasses conventional and simple refraction offering added values with high order aberration data output for customized lenses and observation of patients before and after refractive surgery
