RTVue Premier has created a name for itself as the first Optical Coherence Technology (OCT) cleared device in corneal and retinal imaging in the United States. Real time active eye tracking is thus its noted feature. With the tracking feature, it is possible to collect excellent details of patients who are unable to sit still during scans. This feature is also useful for high myopic patients. This helps the ophthalmologist to give optimal care to patients by providing accurate diagnosis.
