Mean 24-h IOP and daytime (8 am– 8 pm) vs nighttime (11 pm – 5 am) IOP were compared. Changes in OSD signs and symptoms, quality of life (QoL) and in-vivo corneal confocal microscopy (IVCM) were also evaluated.Results: Thirty-eight patients were analyzed. The mean 24-h IOP significantly decreased after 3 months from 17.8 mmHg (95% CI: 17.1– 18.6) to 15.3 mmHg (95% CI: 14.6– 16.1, p < 0.001). IOP was significantly reduced both at daytime (p < 0.001) and nighttime (p < 0.001), with better IOP control at night [− 2.9 (95% CI: − 3.5 to − 2.1) mmHg vs − 2.3 (95% CI: − 2.9 to − 1.6) mmHg]. In 20 patients (52.6%), corneal fluorescein staining improved, whereas in 4 patients (10.5%) it worsened. Hyperemia has improved in 24 (63.3%) patients and worsened in 2 (5.3%). Breakup time, Schirmer test and QoL scores showed no changes. At IVCM, the mean corneal wing-cell size was found significantly decreased (p < 0.005).Conclusion: The switch from BAK-Latanoprost to PF-TTFC significantly reduced IOP over the 24-h and improved OSD signs and symptoms.Keywords: glaucoma, tafluprost-timolol fixed combination, preservative free, BAK, prostaglandins, 24-h effectiveness, ocular surface disease
