SECONDARY outcome
Timeframe: at 12 monthsPopulation: Subjects analyzed were those who were enrolled, randomized to a study arm, and completed the study.
Comprised of 8 categories (conjunctival hyperemia, limbal hyperemia, corneal vascularization, microcysts, Oedema, corneal staining, conjunctival staining and papillary conjunctivitis) each scored on a scale of 0 to 4 where 0=none, and 4=maximum score for each category.

SECONDARY outcome
Timeframe: at 12 monthsPopulation: Subjects analyzed were those who were enrolled, randomized to a study arm, and completed the study.
Visual acuity is measured at high and low contrasts, via the Snellen scale which is then mathematically converted to logMar units. High contrast refers to a darker print on the Snellen chart and is an easier testing environment compared to the low contrast which has a grayer print.
