Ophylosa tear supplement
Tear film dynamics is assessed by non-invasive tear film breakup time (NI-BUT) in parallel with continuous recordings of ocular sensations during forced blinking. Corneal sensitivity thresholds to selective stimulation of corneal mechanonociceptors, thermal receptors and chemical nociceptors are assessed using the Belmonte gas esthesiometer. All baseline measurements are repeated after one month of tear supplementation with zinc-hyaluronate (Ophylosa eye drop) 4x/day
