Purpose: The objective of this study was to analyze prospectively the continuous use of disposable contact lenses.
Methods: We conducted a clinical study of extended wear of disposable contact lenses for a period of 7 days and 6 nights by 25 patients during a 90-day period. Factors such as visual acuity, keratometry, complications, and contamination were analyzed.
Results: Visual acuity and keratometry measurements did not present significant alterations during the study. Complications related to the use of disposable contact lenses were not observed. Analysis of cultures did not present any significant microbiological alterations due to contact lens use. All of the patients were satisfied with the wear schedule and considered the Acuvue lenses comfortable.
Conclusions: Our results may be useful in increasing the level of acceptance of extended wear of disposable contact lenses in Brazil.
