Purpose: To report the risk factors associated with discontinuation of 30 night continuous wear among wearers registered in a post-approval evaluation of lotrafilcon A lenses. Methods: This analysis is part of a multi-center post approval evaluation of continuous wear of lotrafilcon A lenses. Registered wearers completed an extensive baseline questionnaire querying many known and proposed risk factors for unsuccessful contact lens wear. Wearers who discontinue also completed a form citing the reason for discontinuation. Clinical sites will also report reason for discontinuation of lens wear, where known to them. Results: The first 1,000 wearers registered for follow-up in a post-approval evaluation of lotrafilcon A lenses in 87 US clinical sites were given a survey follow up after 3 months in the evaluation. Wearer reported and clinical risk factors measured at registration were analyzed to determine significant associations with discontinuation of wear. Among the risk factors explored will be wearer gender, age, smoking, previous lens experience and wearing schedule, history of contact lens complications, lens power, visual acuity and atopy, among others. Among the wearer cited reasons for discontinuation were discomfort, poor vision, late day dryness, and inability to achieve 30 nights of continuous wear. Conclusions: Risk factors reported at baseline can indicate a wearer's chance of success with 30 night continuous wear. The reasons for discontinuation of 30 night continuous wear can be incorporated into clinical practice when considering 30 night continuous wear of lotrafilcon A lenses.
