IMPORTANCE: Glaucoma treatment has often been associated with adverse side-effects from preservatives that are included in the used eye drops. BACKGROUND: To evaluate changes in the ocular surface and the presence of prostaglandin-induced corneal disorders after being switched from latanoprost 0.005% to low preservative tafluprost 0.0015% ophthalmic solution. DESIGN: Single centre, prospective study. PARTICIPANTS: Patients with primary open-angle glaucoma or ocular hypertension that had received treatment with once daily latanoprost 0.005% ophthalmic solution for control of intraocular pressure (IOP) for 3 months, with a score of above 1 on the National Eye Institute (NEI) ocular surface staining scale. METHODS: Following the ≥3 month latanoprost treatment period, patients were switched to once daily low preservative tafluprost 0.0015% ophthalmic solution. Patients were followed for a minimum of 3 months. MAIN OUTCOME MEASURES: Ocular surface changes were assessed by fluorescein staining score (NEI scale). Additional evaluations included tear break-up time, hyperaemia score, subjective symptoms, changes in intraocular pressure and presence of adverse reactions. RESULTS: Out of 59 patients enrolled, 51 were included in the final analysis. Fluorescein staining scores at baseline, prior to treatment switch, were 6.9 ± 3.1 and 3.3 ± 2.7 at the end of the study period (change in scores was -3.6 ± 2.2 [P < 0.001]). At last follow-up, significant improvements were observed in tear break-up time, hyperaemia score and subjective symptoms (all P < 0.05). CONCLUSIONS AND RELEVANCE: The clinical signs of ocular surface disease and subjective symptoms of dry eyes improved following the switch to low preservative tafluprost and demonstrated comparable IOP lowering effectiveness.
