This is a bilateral, open-label dispensing evaluation of two daily lens types. Eligible subjects will wear the study lenses for 3-months daily wear. 1-Day Acuvue will be worn by spherical subjects and 1-Day Acuvue for Astigmatism will be worn by astigmats.
There is a total of 4 study visits (baseline, contact fitting and dispensing, 1 week, 1 month and 3 month follow-up). Tests conducted include manifest refraction and over-refraction, keratometry, visual acuity, ACA ratio, lens fit assessment, slit lamp biomicroscopy and parent/patient questionaires.
Each child was provided with a supply of lenses to last until the next scheduled follow-up visit, unit-dose rewetting drops for rinsing their lenses if necessary, and a daily log to complete each day until the next follow-up visit.
Informed consent was obtained from all subjects after the nature of the study had been fully explained. The study gained approval from the Ethics Committee of the Singapore Eye Research Institute.
