Near Vision Improvement with the Use of a New Topical Compound for Presbyopia Correction: A Prospective, Consecutive Interventional Non-Comparative Clinical Study.

INTRODUCTION: To report the outcomes in near vision, optical quality and pupil diameter of a new pharmacological therapy (FOV tears) for presbyopia.

METHODS: This was a prospective, consecutive, interventional, non-comparative clinical study in which 117 presbyopic patients were given one drop of the novel therapy (FOV tears) in each eye, followed 2 h after the instillation of the eye drop by an evaluation of the binocular uncorrected near visual acuity (UNVA) and uncorrected distance visual acuity. The objective scatter index and pupil diameter under photopic and scotopic conditions before and after instillation were also assessed. The patients were divided into two groups according to their age, with group 1 patients being 41 and 50 years old and group 2 patients, between 51 and 65 years old.

RESULTS: The mean age of the patients was 50.2 years. The mean UNVA before the use of the eye drop was 0.35 LogMAR, which improved to 0.16 LogMAR at 2 h after the use of the eye drop (p = 0.000). Nine patients did not show an improvement in UNVA, but no patient showed a loss of lines. Fourteen patients (11.9%) reported headaches as a side effect of the therapy.

CONCLUSION: This pharmacological therapy improved near vision by one or more lines (mean improvement 0.18 lines) in 92.3% of the patients at 2 h following the instillation of the eye drops. The group with the youngest patients gained more lines than the group with the oldest patients.
