  3. 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).

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.
Arm/Group Title Clear Care LCS (Stainers) Clear Care LCS (Non-Stainers) ReNU MPS (Stainers) ReNU MPS (Non-Stainers)
Arm/Group Description Clear Care LCS users: Any subject that presented with diffuse punctate staining in three or more peripheral sectors in each eye was classified as a 'stainer' during slit-lamp examination, those who did not were termed 'non-stainers'. Clear Care LCS users: Any subject that presented with diffuse punctate staining in three or more peripheral sectors in each eye was classified as a 'stainer' during slit-lamp examination, those who did not were termed 'non-stainers'. ReNU users: Any subject that presented with diffuse punctate staining in three or more peripheral sectors in each eye was classified as a 'stainer' during slit-lamp examination, those who did not were termed 'non-stainers'. ReNU users: Any subject that presented with diffuse punctate staining in three or more peripheral sectors in each eye was classified as a 'stainer' during slit-lamp examination, those who did not were termed 'non-stainers'.
