PRIMARY outcome

Timeframe: 12 months

Population: Subjects analyzed were those who were enrolled, randomized to a study arm, and completed the study.

Papillary conjunctivitis which is collected as part of the biomicroscopy data and is identified from a slit lamp examination. Grade 0 to Grade 4 with grade 0 implying no health concerns.

SECONDARY outcome

Timeframe: at 12 months

Population: 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 months

Population: 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.
