Brief Summary

Evaluation of the safety and tolerability of PRO-201 (0.01% sulfate atropine) after its instillation on the ocular surface of healthy volunteers through the following variables: unexpected adverse events incidence and photophobia (primary outcome variables); as well as pupillary diameter, expected adverse events incidence, best near corrected visual acuity (BNCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal and conjunctival staining, heart rate, blood pressure and ocular confort index (OCI),
