Secondary Outcome Measures
- Intensity of Physiological Outcomes [24 weeks]

Mean of physiological outcomes for those subjects who are identified as susceptible versus non-susceptible for "Solution Induced Corneal Staining (SICS)". Average wearing time and average comfortable wearing time.
- Physiological Responses [24 weeks]
Mean of physiological outcomes for those subjects who are identified as susceptible versus non-susceptible for "Solution Induced Corneal Staining (SICS)". Physiological findings are done through a slit lamp examination and are known as biomicroscopy measurements. Measures are given in terms of average score with a minimum of zero and a worse grade the higher the value with a range of 0 to 4, (tarsal roughness is 0-7 scale).

Title | Physiological Responses |
---|---|
Description | Mean of physiological outcomes for those subjects who are identified as susceptible versus non-susceptible for "Solution Induced Corneal Staining (SICS)". Physiological findings are done through a slit lamp examination and are known as biomicroscopy measurements. Measures are given in terms of average score with a minimum of zero and a worse grade the higher the value with a range of 0 to 4, (tarsal roughness is 0-7 scale). |
Time Frame | 24 weeks |
Outcome Measure Data
Analysis Population Description |
---|
All subjects, enrolled, randomized, and completed the study. Subjects where identified as 'stainers' or 'non-stainers' and outcomes were reported by this stratification. |
