PRIMARY outcome

Timeframe: V1 (Initial), V2 (Day-7), V3 (Day-14), V4 (Day-30)

Population: Not all subjects completed the study measures at each outcome measurement time frame before the study was terminated. 20 participants completed V1 and only 1 participant completed the V2 follow-up. V3 and V4 cannot be analyzed.

Subjective responses of participants administered by questionnaire and measured on a linear scale (0-100) measured at each visit.

PRIMARY outcome

Timeframe: Change from baseline over 30 days measured at V1 (Initial), V2 (Day-7), V3 (Day-14), V4 (Day-30)

Population: Not all subjects completed the study measures at each outcome measurement time frame before the study was terminated. 20 participants completed V1 and only 1 participant completed the V2 follow-up. Change from baseline V1 over 30 days V4 cannot be analyzed.

Ocular health determined by biomicroscopy recorded on a severity scale (0-4) for change from baseline over 30 days.
