Efficacy and ocular surface tolerability of preservative-free tafluprost 0.0015%: a 6-month, single-blind, observational study on naïve ocular hypertension or glaucoma patients.

OBJECTIVES

The aim of this study was to evaluate the safety of preservative-free tafluprost in newly diagnosed patients and to confirm its efficacy in lowering intraocular pressure (IOP).

METHODS

Naïve patients were submitted to an ophthalmic examination, including ocular surface status and quality of life evaluation. All examinations were performed at baseline and after 1 and 6 months.

RESULTS

28 patients were enrolled and treated with tafluprost, once a day, in the evening. TF-BUT changed from 9 (interquartile range (IQR) 6 - 11) s at baseline to 10 (IQR 7 - 10) s at 1 month (p = 0.106) and 9 (IQR 6 - 12) s at 6 months (p = 0.003). No eye developed corneal staining. Quality of life was (median (IQR)) 91.6 (79.2 - 95.8) at baseline and 95.8 (66.7 - 100) at 6 months (p = 0.62). Only a few adverse events occurred during the follow-up period (three patients experienced ocular burning and one developed redness). The mean IOP reduction was 5.5 mm Hg (95% CI 3.8 - 7.2). The median (IQR) baseline IOP was 18.7 (15 - 23.7) mm Hg; 14 (13 - 16) mm Hg and 16 (14 - 16) mm Hg (p < 0.0001) after 1 and 6 months, respectively.

CONCLUSION

No patient developed ocular surface disease and quality of life perception was preserved. Preservative-free tafluprost is therefore an effective drug that is safe for the ocular surface after 6 months of daily therapy.
