Dry Eye
Conditions
Brief summary
The purpose of this study is to evaluate the safety profile of test formulations for an artificial tear product versus a comparator product.
Detailed description
Subjects will be randomized to one of five different treatment sequences. Subjects will attend 6 scheduled visits with an expected individual duration of participation of 11 to 42 days. This study will be conducted in Australia.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Treatment-Emergent Adverse Events (AEs) | Up to Day 30 (Study Exit) | 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. |
| Number of Subjects with Biomicroscopy Findings Outside of Normal Limits | Screening, up to Day 30 (Study Exit) | The cornea, conjunctiva, and eyelid will be assessed using a slit lamp. The number of subjects with biomicroscopy findings outside of normal limits will be recorded. |
| Mean Total Ocular Surface Staining Score | Screening, up to Day 30 (Study Exit) | Ocular surface staining will be assessed using a slit lamp and recorded on a 15-point scale. |
| Mean Best Corrected Visual Acuity (BCVA) | Screening, up to Day 30 (Study Exit) | Visual Acuity will be assessed with correction in place using letter charts. BCVA will be measured in logarithm Minimum Angle of Resolution (logMAR). |
| Number of Device Deficiencies | Up to Day 30 (Study Exit) | A device deficiency is inadequacy of a medical device with respect to its identity, quality, durability, reliability, safety, or performance. The number of device deficiencies as observed or reported will be recorded. |
