SSR (spatially resolved refractometer): a null-seeking aberrometer.
The spatially resolved refractometer is an aberrometer used to measure the wave-front aberrations of the human eye. In its original form and the new configuration that we report, it uses the patient's perception in a psychophysical task to evaluate the wave-front errors at a variable number of loci (typically 40 or 160) across the cornea. This configuration includes pupil tracking and the ability to choose the measurement loci in software. An automated configuration that does not require patient input is also described.
