This is a prospective, single center, randomized, bilateral crossover, dispensing clinical trial to evaluate the effects of the water gradient lens, DAILIES TOTAL1, on the biology of corneal epithelium over two months of daily wear compared to wear of a control high oxygen permeable silicone hydrogel daily disposable contact lens, the ACUVUE TruEye; and to correlate these changes with alterations in the lid wiper, tear film and cellular changes at the limbus. The total proposed duration of this study is 12 months to ensure enrollment of up to 94 established contact lens wearers, with anticipated completion of 84. Data will be collected at baseline and following 2 months of daily wear for each lens type. Based upon data from the investigators previous contact lens clinical trials, a 1 month washout period is required prior to initiating lens wear to eliminate any potential residual solution or lens effects on the corneal epithelium and restore homeostasis. The study is scheduled to commence upon Institutional Review Board approval.
