Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Treatment-Emergent Adverse Events (AEs)
Time Frame: Visit 2 [1 to 7 days after Visit 1/Screening (Day 1)] through Exit Visit. Exit Visit will occur 3 to 13 days after Visit 2 depending on observed visit windows.]
An AE is any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory findings) in subjects, users, or other persons, whether or not related to the investigational medical device (test product). The number of adverse events as observed or reported will be recorded.
Visit 2 [1 to 7 days after Visit 1/Screening (Day 1)] through Exit Visit. Exit Visit will occur 3 to 13 days after Visit 2 depending on observed visit windows.]
Number of Subjects with Biomicroscopy Findings Outside of Normal Limit
Time Frame: Visit 1/Screening (Day 1) through Exit Visit. Exit Visit will occur 4 to 20 days after Visit 1 depending on observed visit windows.
The investigator will observe the corneal and other ocular structures under white light of the slit lamp. The number of subjects with biomicroscopy findings outside of normal limits will be recorded.
Visit 1/Screening (Day 1) through Exit Visit. Exit Visit will occur 4 to 20 days after Visit 1 depending on observed visit windows.
Best Corrected Visual Acuity (BCVA)
Time Frame: Visit 1/Screening (Day 1) through Exit Visit. Exit Visit will occur 4 to 20 days after Visit 1 depending on observed visit windows.
BCVA will be assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) letter charts and recorded in logarithm Minimum angle of resolution (logMar).
Visit 1/Screening (Day 1) through Exit Visit. Exit Visit will occur 4 to 20 days after Visit 1 depending on observed visit windows.
