| Distance VA (logMAR) With Study Lenses - Completed Eyes | Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned. | Dispense, Week 1 follow-up, Week 2 follow-up, Month 1 follow-up, Month 2 follow-up, Month 3 follow-up (at least 4 hours after lens insertion at each follow-up assessment visit) |
| Distance VA (logMAR) With Study Lenses - Discontinued Eyes | Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned. | Dispense, Week 1 follow-up, Week 2 follow-up, Month 1 follow-up |

Adverse events (AE's) were collected from time of consent to study exit, approximately 3 months.
AE's were obtained through solicited and spontaneous comments from subjects and through observations by the Investigator. "At Risk" population for ocular AEs is reported in units of eyes; all other populations are reported in units of participants. This analysis population includes all enrolled and dispensed subjects.
