Video Pupillometer

pMetrics® is a fully integrated component of the iVis Suite™ that was developed in-house. It enables the customization of the optical zone for refractive surgery purposes, thereby reducing the invasiveness of the procedure, through the use of the patented Ideal Pupil determination.



The pMetrics® system evaluates six (6) distinct lighting environments to accurately pinpoint pupil dynamics and simulate a complete range of scotopic to photopic variable environments. In order to ascertain the Ideal Pupil, which encompasses 95% of all pupil conditions of the patient during awake hours, the recorded data are compared to the patient's lifestyle.input:
output:The invasiveness of the treatment is minimized by pMetrics®, which accurately defines the real optical zone of the ablation to be treated. This is achieved by considering the anterior chamber depth and the Ideal Pupil computation.input:
output:The customized near vision inner refractive zone for multifocal refractive treatments and to support the customized selection of multifocal IOLs can also be determined using pMetrics®.input:
output:Optimal Student

A comprehensive examination of the patient's pupil dynamics is necessary for modern refractive and cataract surgeries. The application of standard-size ablation dimensions to estimate pupil dimensions or to assume that pupils are "normal" sized results in either an optical zone that is too small, resulting in lasting halos or starbursts, or, conversely, the unnecessary removal of corneal tissue.input:
output:In refractive surgery, the one-size-fits-all ablation dimension approach is eliminated by pMetrics®, which employs robust science.input:
output:The binocular pupil responses to six calibrated light conditions, which include diffuse lighting and glare sources, are dynamically tested by pMetrics®. These conditions range from scotopic to photopic.
