Research summary
The purpose of this study is to compare the subjective performance over a three week period of two brands of contact lenses worn on a daily disposable basis. Both brands are CE marked products i.e. approved for use in the European Union.
This is a 54 participant, double-masked (participants will be masked to lens type and investigators will be masked to the lens coding) three-part, crossover dispensing study. For the first week, participants will wear both brands of lenses, one brand in in each eye (1 week of contralateral wear). The following two weeks will be a bilateral crossover where participants will wear the same lens brand in each eye for one week each.
The study will be conducted at three optician practices in England and is being sponsored by a major contact lens manufacturer.
Participants will be existing soft contact lens wearers recruited on the basis of having healthy eyes apart from needing correction for short-sightedness. Approximately half of the participants will be symptomatic contact lens wearers i.e. they will have a comfortable wearing time 2 hours less than the average wearing time and experience symptoms of late day dryness
Participants will need to attend the study site on four occasions for approximately 30-40 minutes per visit over a period of approximately 3 weeks.REC name
