Suboptimal compliance and impaired long-term outcome are a likely result of poor tolerability. The present multicentre, international, transverse, epidemiological survey was conducted to assess the satisfaction of patients who had received preservative-free latanoprost (PFL) for at least 3 months.Patients and Methods: A total of 1872 patients from 6 European countries, treated with PFL for at least 3 months, were included in this survey. Prior to PFL treatment, patients were to be treatment naïve or currently treated for their glaucoma. During a single routine consultation, patients completed a questionnaire concerning global satisfaction and satisfaction based on tolerability.Results: In total, 76.2% had been previously treated; 69.4% had received preserved and 6.8% preservative-free (PF) topical treatment. After 3 months of PFL treatment, a large majority of patients (95.3%) were satisfied or very satisfied with their PFL treatment and were, overall, significantly (p< 0.0001) more satisfied with PFL than with their previous treatment; 4.2% were either unsatisfied or very unsatisfied. Overall, 97.3% of originally treatment-naïve patients were satisfied (50.1%) or very satisfied (47.2%) with their PFL. Ocular surface disease was diagnosed in 9.2% of patients (n=173) and was mainly mild (76.9%). Patient satisfaction with PFL was very high. Conclusion: PFL may be considered a valuable first-choice treatment in glaucoma patients.Keywords: glaucoma, prostaglandin, preservative-free latanoprost, patient satisfaction, tolerability, tear substitutes, intra-ocular pressure, ocular surface disease, conjunctival hyperaemia
