| Popis: | BACKGROUND AND OBJECTIVES: Ozurdex intravitreal injection is performed via a patented injection device. However, there is a common misconception among ophthalmologists regarding the relation between the speed of applicator button depression and the speed of pellet injection. PATIENTS AND METHODS: Six dexamethasone intravitreal implants were injected into a calibrated ex vivo water bath. Three of the pellets were injected via rapid compression, whereas the other three implants were injected using a 3-second compression technique. The procedures were recorded using high-speed photography followed by calculation of pellet velocity and impact force. RESULTS: The mean impact velocity and force of the pellet insertion is significantly higher in the fast injection group compared to the slow injection group. CONCLUSIONS: By depressing the Ozurdex implant injector during a 3-second time interval, the impact force of the implant pellet is reduced by about 95%. This new technique will theoretically reduce the risk of retinal injury and vitreous hemorrhage from Ozurdex injections. [ Ophthalmic Surg Lasers Imaging Retina. 2019;50:e23–e25.] |
