Lens Wearing Experience and Biocompatibility of a Marketed Multi-Purpose Disinfecting Solution in Silicone Hydrogel and Soft Contact Lens Wearers

Mean Change From Baseline (Day 0) in Average Corneal Staining Area at Day 30

Percentage corneal staining was assessed by the investigator for each of five regions of the cornea; i.e., four quadrants plus central. The investigator instilled flourescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and yellow filter. Percentage corneal staining was recorded in increments of ten, and the percentages of the five regions were averaged together.

Mean Change From Baseline (Day 0) in Total Corneal Staining Type at Day 30

Corneal staining type was assessed by the investigator for each of five regions of the cornea, i.e., four quadrants plus central. The investigator instilled flourescein dye and examined the cornea with a slit lamp, i.e., biomicroscope and yellow filter. Corneal staining type was recorded on a 5-point scale for each region: 0=none; 1=micropunctate; 2=macropunctate; 3=coalesced macropunctate; 4=patch (\>/= 1 mm). The five regions were summed, for a summed total range of 0-20.
