BACKGROUND: Intraocular pressure (IOP)-lowering medications for primary open-angle glaucoma and ocular hypertension commonly contain preservatives that can cause ocular surface damage in many patients. The purpose of this study was to evaluate the efficacy and tolerability of, and compliance to, preservative-free (PF) bimatoprost 0.03% in patients with primary open-angle glaucoma or ocular hypertension (IOP ≥18 mmHg) in a clinical practice setting. METHODS: This open-label study observed patients who were switched to PF bimatoprost 0.03% for medical reasons. IOP was measured at baseline and ~12 weeks later at the final visit, and the change in IOP was calculated. Tolerability and continuation of therapy were assessed at two follow-up visits. RESULTS: A total of 1,830 patients were included in the study, and complete IOP data were available for 1,543 patients. Mean IOP was reduced by 23% from 21.64 mmHg to 16.59 mmHg (P<0.0001). In subgroup analyses, the mean IOP was significantly reduced compared with baseline, regardless of prior therapy, including those previously treated with PF monotherapy. A total of 85.7% of physicians reported the IOP-lowering efficacy of PF bimatoprost 0.03% to be as expected or better than expected. Adverse events (AEs) were experienced by 5.7% of patients, and there were no serious AEs reported. The most common AEs were eye irritation (1.7%) and hyperemia (1.4%). Physician-reported treatment compliance was reported as better than (48.7%) or equal to (43.6%) prior treatment in most patients. Most patients (82%) were expected to continue PF bimatoprost 0.03% after the end of the study. CONCLUSION: This observational study showed that, in clinical practice, switching to PF bimatoprost 0.03% was associated with a significant IOP reduction from baseline. There was a low AE rate. PF bimatoprost 0.03% may, therefore, be an effective treatment option for patients who are intolerant of preservatives or have an inadequate response to prior IOP-lowering treatments.
