- Limitations and caveats
The subjective nature of the OSDI may not be sensitive enough to detect the effects of preservatives on the corneal surface. The measurement and quantification of OSD remains a considerable clinical challenge. (Pflugfelder and Baudoin, 2011)

Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Mean Change at Day 90 From Baseline (Day 0) in Ocular Surface Disease Index (OSDI) Score | Baseline, Day 90 | The OSDI is a 12-question validated questionnaire (resultant overall 0-100 point score) used to measure ocular symptoms, visual function and environmental factors that may affect a patient's vision, where 0 = normal and 100 = severe. The OSDI questionnaire was administered at both visits and completed by the patient with no assistance from the office staff, physician, or anyone else. The baseline OSDI score was subtracted from the 90-day OSDI score and reported as change. A negative number represents a perceived improvement in ocular health. |
| Secondary | Percentage of Patients With Corneal Fluorescein Staining Score = 0 | Day 90 | The corneal surface was assessed by the investigator and graded on a scale of 0-3, where 0 = Absent (no staining present) and 3 = Severe (\>50% coverage). Percentage of patients with score = 0 at 90 days was calculated by dividing the number of patients with score = 0 by the total number of patients analyzed. |
