Designed in-house and fully integrated into the iVis Suite™, pMetrics®, by means of the patented Ideal Pupil determination, allows the customization of the optical zone for refractive surgery purposes, to minimize surgical invasiveness.
pMetrics® assess six (6) different lighting environments in order to simulate a full range of scotopic to photopic variable environments and thus, accurately pinpoint pupil dynamics. The recorded data are matched with patient’s lifestyle in order to determine the Ideal Pupil which encompasses 95% of all pupil conditions of the patient during awake hours.
pMetrics® accurately defines the real optical zone of the ablation to be treated, based upon the Ideal Pupil computation while taking into account the anterior chamber depth, and thus minimizing the invasiveness of the treatment.
pMetrics® also allows the determination of the customized near vision inner refractive zone for multifocal refractive treatments and to support the customized selection of multifocal IOLs.
Ideal Pupil
Contemporary refractive and cataract surgeries require complete analysis of the patient’s pupil dynamics. To estimate pupil dimensions or to assume that pupils are “normal” sized, applying standard-size ablation dimensions results in either too small optical zone with lasting halos or starbursts, or conversely the unnecessary corneal tissue removal.
pMetrics® applies strong science to eliminate the one-size-fits-all ablation dimension approach in refractive surgery.
pMetrics® tests dynamically the binocular pupil responses to 6 calibrated light conditions ranging from scotopic to photopic and includes diffuse lighting and glare sources.
