PRIMARY outcome

Timeframe: Post lens insertion (baseline)

Population: Analysis was conducted on subjects who were enrolled, randomized, and successfully completed the study.

Snellen monocular visual acutity (VA) assessed by the Investigator and was converted to the LogMAR scale.

PRIMARY outcome

Timeframe: Post lens insertion (baseline)

Population: Analysis was conducted on subjects who enrolled, were randomized, and successfully complete the study per protocol.

Snellen binocular visual acuity assessed by the Investigator and was converted to the LogMAR scale. A value \<0 implies clinically positive results, a value \>0 implies clinically negative results

SECONDARY outcome

Timeframe: After 6-8 days of lens wear

Population: Analysis was conducted on subjects who successfully completed the study.

Limbal redness was assessed using a 5-point slit lamp classification scale (5-Worst, 0-None). Only those eyes with limbal redness grade \>= 3 were reported for purposes of this analysis. Grades 3 -5 are considered to be part of the adverse events reporting.
