Abstract

BACKGROUND - METHODS - RESULTS - CONCLUSION; Intravitreal medication injections are an efficient and low-risk delivery technique for treating various retinal diseases. Rare serious complications include increased intraocular pressure, vitreous hemorrhage, retinal tears and detachment, intraocular inflammation and endophthalmitis. In the case series presented here, we report iatrogenic lens injuries caused by inadequate performance of intravitreal injections.; A multicenter data collection of patients treated with intravitreal injections with visible iatrogenic lens defects from 2016 to 2023 was retrospectively performed.; Lens trauma after intravitreal injections was identified in six cases (69.3±6.5 years). While five cases were observed after anti-VEGF therapy, we identified lens injury after dexamethasone implantation in one patient.; Iatrogenic lens injury during intravitreal injection is preventable with the correct injection technique. Knowledge of individual axis length and lens status also helps to avoid this complication.
