Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Is the degree of pupildilation, achieved after administrating a 4.5 microliter microdrop tropicamide 0.5% equivalent to the pupildilation after a regular 30 microliter eydrop tropicamide 0.5% in healthy volunteers? ;Secondary Objective: Is there a subjective difference in the degree of physical discomfort, experienced after administration of a microdrop compared to a regular eyedrop? Qualitative evaluation of the mydriatic reponse/time curves of both the microdrop and the regular eyedrop.;Primary end point(s): Within-subject pupildilation (compared to baseline) of a regular eyedrop and a microdrop at t=40 min.;Timepoint(s) of evaluation of this end point: 40 minutes after eyedrop administration | — |
