- Primary Outcome Measures
Name Time Method Vision Quality after 1 week of lens wear This outcome is a weighted combined score calculated from individual vision-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.
Subjective Rating of Handling after 1 week of lens wear This outcome is a weighted combined score calculated from individual lens handling-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.
Subjective Rating of Quality Perceptions after 1 week of lens wear This outcome is a weighted combined score calculated from individual quality perception-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.
Corneal Staining after 1 week of lens wear Investigator assessment of the corneal staining. Staining is an indication of dryness on areas on the cornea. Here it is measured over 5 regions of the cornea: central, temporal, nasal, inferior, and superior. The staining is graded using the National Eye Institute (NEI)0-3 scale: grade 0 = normal, grade 1 = mild, grade 2 = moderate, grade 3 = severe.
Limbal Hyperemia after 1 week of wear This outcome is assessed by the investigator during biomicroscopy examination using the following 0-4 scale: 0 = none, 1 = trace, 2 = mild, 3= moderate, 4 = severe.
Subjective Rating of Comfort after 1 week of lens wear This outcome is a weighted combined score calculated from individual comfort-related questions asked on a 1-5 scale: 1 = most negative response to 5 = most positive response.
