Eligibility
Inclusion criteria
* were at least 18 years old; * were experienced contact lens wearers; * were correctable to at least 20/40 or better in both eyes with contact lenses; * were in good general health, with healthy eyes (other than requiring vision correction); * had not worn lenses for at least 12 hours before each baseline visit; * had a corneal staining score no greater than Grade 1 in either eye at time of enrollment; * had previously used an MPS or hydrogen peroxide solution successfully.
Exclusion criteria
* had a confirmed diagnosis of Sjögren's syndrome or other condition that results in a chronic and/or pathologic dry eye condition; * required concurrent ocular medication or have used ocular medication within 24 hours of entering the study; * had a known sensitivity or intolerance to any MPS, study products or ingredient(s); * were currently participating in any other clinical study; * had a condition or are in a situation that, in the investigator's opinion, may put them at significant risk, confound the study results, or interfere significantly with their participation in the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Eyes With No Change in Corneal Staining | Change from baseline after 1, 2, 4 and 6+ hours of wear | Subjects examined after corneal staining (a method used to assess the condition of the cornea) using a slit lamp to determine change from baseline and rated based on the following scale: 0=no change from baseline, 1=trace, 2=mild, 3=moderate, 4=severe. |

Recruitment details
Recruitment of employees occurred 7/8/2010 - 10/1/2010 thru employee bulletin for study taking place at in-house optometric clinic.
Pre-assignment details
Prior to baseline visit subjects were instructed to undergo a washout period where no contacts were worn for 12 hours. Slit lamp exam was conducted prior to randomized group assignment. Eyes were thoroughly rinsed with unit-dose aline before pre-soaked study lenses were inserted.

Outcome results
Number of Eyes With No Change in Corneal Staining
Subjects examined after corneal staining (a method used to assess the condition of the cornea) using a slit lamp to determine change from baseline and rated based on the following scale: 0=no change from baseline, 1=trace, 2=mild, 3=moderate, 4=severe.
Time frame: Change from baseline after 1, 2, 4 and 6+ hours of wear
