Three-year follow-up of biomicroscopy signs and refractive status in patients wearing lotrafilcon A lenses.

Purpose. To report the wearer experience, biomicroscopy signs, and stability of refractive error after 3 years’ use of lotrafilcon A lenses. Methods. Seventy-four subjects from a multicenter clinical trial with lotrafilcon A lenses were queried on aspects of lens wear. Biomicroscopy signs and refractive error were compared to baseline measurements. Results. A total of 66% of subjects reported continuing to wear lotrafilcon A lenses, usually for more than 21 nights, with high satisfaction. Signs of limbal, palpebral, and bulbar redness improved significantly. Average refractive error remained stable. Conclusions. Long-term use of lotrafilcon A lenses resulted in high wearer satisfaction, reduction of ocular redness, and stable refractive error.
