Purpose:
The primary purpose of this study is to assess the comfort and vision of Dailies Total1® for Astigmatism contact lenses in subjects dissatisfied with their previously worn toric contact lenses.
Patients And Methods:
In this prospective, non-comparative study, subjects aged 18 to 39 years with a history of unsuccessful previous astigmatism contact lens wear were recruited. Subjects were allocated and fitted with varying astigmatism powers of the Dailies Total1® for Astigmatism contact lenses. After 30 days of wear, participants responded to a questionnaire consisting of a visual analog scale assessing overall comfort and vision and a Likert scale assessing comfort and vision throughout the day, at the end of the day (EOD), and as it pertains to real-world tasks.
Results:
Sixty-five subjects (130 eyes) completed the study, of which 50 were female, and 15 were male, with a mean (± standard deviation) age of 29.5 ± 5 years. Overall, 87.69% of the subjects reported a positive rating for comfort and 92.31% for satisfaction with vision. 78% of respondents reported positive ratings for comfort throughout the day and 55% at the end of the day. Comfort while working on the computer and utilizing a cellphone was rated at 80% and 86%, respectively. 85% either agreed or strongly agreed that the lenses provided clear vision throughout the day, and 71% at the end of the day. Positive ratings for vision while on the computer and while using a cellphone were 87% and 91%, respectively. Of all participants, based on comfort and vision, 58% favored continuing to wear the lenses after the study.
Conclusion:
The results suggest that Dailies Total1® for Astigmatism contact lenses offer favorable comfort and vision for individuals who had previously been dissatisfied with their toric lenses.
