Two types of daily disposable soft contact lenses, 1-Day Acuvue (Johnson & Johnson K.K., Japan) and Focus Dailies (CIBA Vision Corp.), were compared for comfort, user preference, and any associated incidence of corneal complications.
1-Day Acuvue® and Focus Dailies® were randomly prescribed for one eye each of 127 contact lens wearers. After 1 week of lens wear, user preference, anterior segment health, and tear film stability on the contact lenses were evaluated.
Group A consisted of 45 subjects who had been wearing 1-Day Acuvue prior to the study and group B consisted of 82 subjects who had been wearing other types of soft contact lenses prior to the study. A statistically significant number of subjects in both group A and group B preferred 1-Day Acuvue. In group A there were significantly fewer corneal complications in the eyes with 1-Day Acuvue than in the eyes with Dailies. However, there was no difference in the incidence of corneal complications in group B.
If Dailies are prescribed for current 1-Day Acuvue wearers, extra care may be required. 1-Day Acuvue lenses could be prescribed successfully for those who previously wore soft contact lenses other than 1-Day Acuvue.
