Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Slit Lamp Findings | 3 months | Each subjects' eye was examined using a bio-microscope. Slit lamp findings were graded with a 5-point scale (i.e. Grade 0= None, Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe). The number of eyes with Grade 3 or higher for each lens was reported for each assessment. |
| Distance Visual Acuity (LogMAR) | Up to 3 Months | Distance visual acuity was collected at the 1-, 2-, 3-week and 1- and 3- month follow-up evaluations. The average LogMAR across all visits for each lens type was reported. |

Pre-assignment details
A total of 312 subjects were enrolled in this study. Of the enrolled subjects 12 did not meet the eligibility criteria and 300 were randomized to treatment using an allocation of 2:1 for test and control, respectively. Of the 300 randomized subjects 13 were discontinued from the study and 287 subjects completed the study.

Outcome results
Distance Visual Acuity (LogMAR)
Distance visual acuity was collected at the 1-, 2-, 3-week and 1- and 3- month follow-up evaluations. The average LogMAR across all visits for each lens type was reported.
Time frame: Up to 3 Months
Population: The analysis population consists of subjects that completed all study visits without a major protocol deviation.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Experimental Multi-purpose Solution | Distance Visual Acuity (LogMAR) | -0.030 LogMAR | Standard Deviation 0.0639 |
| ReNu MultiPlus Multi-Purpose Solution | Distance Visual Acuity (LogMAR) | -0.031 LogMAR | Standard Deviation 0.0634 |
Slit Lamp Findings
Each subjects' eye was examined using a bio-microscope. Slit lamp findings were graded with a 5-point scale (i.e. Grade 0= None, Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe). The number of eyes with Grade 3 or higher for each lens was reported for each assessment.
Time frame: 3 months
Population: The analysis population consists of all subjects that were dispensed a solution during the course of the study.
