Summary: To investigate the effect of 30-days continuous-wear of the lotrafilcon A contact lenses on corneal physiology with special focus on the tear film evaluation, corneal topography and corneal thickness changes. Methods: Seventy patients (140 eyes) wearing continuously lotrafilcon A lenses (Air Optix NIGHT & DAY) for monthly replacement were observed for two years. Complete ophthalmologic examinations and corneal topography were performed before fitting (visit 0) and at each follow-up visit, namely in month 12 (visit 12) and month 24 (visit 24). Purpose of the clinical study: anamnesis, refraction, slit lamp examination, keratometry, pachymetry (corneal thickness), endothelium evaluation, tear film evaluation using TEARSCOPE, photographic documentation using IMAGINET 2000. Corneal topography was performed with Orbscan II device and consisted of: axial keratometry map pattern, SimK, irregularity in 3.0 and 5.0 millimeters area, pachymetry in the thinnest point were evaluated and compared during 0, 12 and 24 (month) visit. Results were statistically analyzed. 24 (month) visit. Results and conclusions: Very good assessment of fluoro-silicone hydrogel contact lens for extended wear in the clinical study was observed. Results and conclusions: Very good assessment of fluoro-silicone hydrogel contact lens for extended wear in clinical study.
