A treatment-emergent adverse event was defined as any event that occurred or worsened on or after the day randomized study intervention was initiated. At each study visit, subjects were verbally asked by clinic staff to report any changes to any aspect of their ocular health. Ocular treatment-emergent adverse events reported by the subject or observed by the investigator were summarized by preferred term for overall incidence calculation. This was a subject-based assessment.

Cell density in the central corneal endothelium was assessed using specular microscopy imaging. Overall average cell density was calculated as the average of the average cell densities of three images and was measured in cells per millimeter squared (cells/mm^2). A negative change from baseline represents a less desirable outcome.

Visual acuity with correction in place (spectacles or a trial frame with lenses) was measured using Early Treatment Diabetic Retinopathy Study (ETDRS) letter charts (original or modified) at a distance of 10 feet. Each line on the ETDRS chart typically has five letters, and each letter correctly identified adds to the overall score. ETDRS letter scores range from 0 to 100, with each letter correctly identified representing a score of 1. A perfect score of 100 is achieved when all 70 letters on the chart are correctly identified. 85 letters correctly identified corresponds to normal distance eyesight.

Visual acuity with correction in place (spectacles or a trial frame with lenses) was measured using Early Treatment Diabetic Retinopathy Study (ETDRS) letter charts (original or modified) at a distance of 10 feet. Each line on the ETDRS chart typically has five letters, and each letter correctly identified adds to the overall score. The overall letter score was converted to Logarithmic minimum angle of resolution (LogMAR). LogMAR scores typically range from -0.3 to 1.0, where zero represents normal vision, negative values indicate better than normal vision, and positive values indicate poorer than normal vision.

Total corneal (fluorescein) staining score ranges between 0 and 5. Total conjunctival staining score is collected as the sum of lissamine green staining nasal and temporal scores and ranges between 0 and 10 per eye. Total ocular staining score is collected as the sum of total corneal and conjunctival scores (0 to 15) with a maximum possible score of 15 per eye. A higher total score indicates greater staining (or worse condition).
