Introduction: The demand for intravitreal therapy has increased dramatically with the introduction of vascular endothelial growth factor inhibitors. Improved utilisation of existing resources is crucial to meeting the increased future demand. We investigated time spent preparing intravitreal injection treatment using either prefilled syringes or vials in routine clinical practice. Methods: We video-recorded preparations of intravitreal injections (n = 172) for each preparation type (ranibizumab prefilled syringe (n = 56), ranibizumab vial (n = 56) and aflibercept vial (n = 60)) in a multi-centre time and motion study. The preparation times for each step were extracted from videos and the three preparation types were compared. Results: Prefilled syringes eliminated several steps in the preparation process. Total preparation time was 40.3-45.1 sec. using vials, and the use of prefilled syringes saved 25.5 sec. (95% confidence interval (CI): 23.3-27.6 sec., p < 0.0001). The preparation time when aflibercept vials were used was 3.7 sec. (95% CI: 1.45-5.96 sec., p = 0.0014) longer than when ranibizumab vials were used. ConclusionS: Prefilled syringes for intravitreal injections reduce preparation time by eliminating preparation steps that both entail a risk of contamination and are subject to variation. The amount of time saved may enable increased utilisation of existing resources and outsourcing to nonophthalmologists.
