65A Single-Center study to demonstrate the non-inferiority of EM-100 to Zaditor® in the treatment of ocular itching.
Subjects will receive one drop in one eye only based on the randomization list, one time over the course of the trial.

Ocular itching scores were self-assessed by the participant using a 5-point scale with 0.5 unit increments, wherein 0 = None (normal, no itching), 1.0 = Intermittent tickle sensation involving more than just the corner of the eye, 2.0 = Mild continuous itch without desire to rub, 3.0 = Severe itch with desire to rub, and 4.0 = Incapacitating itch with irresistible urge to rub.
The investigator assessed conjunctival redness scores using a 5-point scale with 0.5 unit increments, wherein 0 = None (normal, no dilated blood vessels), 1 = Mild (slightly dilated blood vessels: pink color; can be quadrantal), 2 = Moderate (more apparent dilation, with redder color, involving majority of the vessel bed), 3 = Severe (numerous and obvious dilated blood vessels, with deep red color and no color, or less red with chemosis), and 4 = Extremely Severe (large, numerous, dilated blood vessels characterized by unusually severe deep red color regardless of chemosis and involving the entire vessel bed).
