Sumario:PURPOSE: To analyze the use of artificial tears in patients undergoing treatment with anti-vascular endothelial growth (anti-VEGF) intravitreal injections. METHODS: Thirty-four eyes undergoing anti-VEGF treatment were analyzed. Each patient underwent a subjective and objective evaluation of the ocular surface, using the Ocular Surface Disease Index (OSDI), Dry Eye Questionnaire (DEQ)-5, tear meniscus height (TMH), first and average non-invasive Keratograph Break-Up Time (NIKBUT), bulbar conjunctival redness, meibography and the Vision Break-Up Time (VBUT). Patients attended 5 visits (days 0, 7, 30, 37, and 60). All patients continued with their intravitreal injection treatment during the study (days 0, 30, and 60). Patients did not receive any artificial tear treatment during the first month of the study, and at the baseline visit they were randomly assigned to one of two study groups to receive either the Systane Hydration or the Viscofresh 10mg/mL formulation. Patients were instructed to instill one drop of the assigned study treatment 3 times a day for 30 days during the second month of the study. RESULTS: According to the Mixed Models for Repeated Measures analysis, there is not enough statistical evidence for any of the parameters examined to determine significant differences between being treated with artificial tears and not being treated (p > 0.05). There is, however, a tendency toward improved outcomes in some parameters when artificial tears were used. OSDI, DEQ-5, TMH, and meibography were not affected by either the type of artificial tear used or by the time (from day 30 to day 60; p > 0.05), but the NIKBUT and VBUT values increased over time during this period regardless of which treatment the patient was receiving. CONCLUSION: The use of artificial tears may help to keep the tear film stable Future studies with larger samples should be conducted to elucidate whether the tendency reported in our study becomes significant.
