Abstract Details


Intravitreal injections (IVT) and cataract surgery are frequently performed procedures. Evidence of cases of unintentional injury of the lens due to IVT injections is documented in the literature. Injury as such might bring about an elevated incidence of surgical complications during and after cataract surgery. The purpose of this research is to investigate whether prior IVT injection treatment causes increased incidence of intraoperative and postoperative complications of cataract surgery


A retrospective cohort analysis


A retrospective cohort analysis reviewed all patients who underwent cataract surgery at Soroka University Hospital between January 2010 to September 2015. 236 patients with prior IVT injection treatments were included, and a control group of 241 patients was matched. Data analyzed included demographic information, preoperative clinical characteristics, prevalence of intraoperative and postoperative complications, and postoperative clinical outcomes


No difference between the research group and the control group was identified regarding postoperative complications, nor regarding the outcome of combined intraoperative and postoperative complications 12 in the research group compared to 11 in the control group. (P=0.708)


Contrary to our hypothesis, no correlation was found between prior treatment of IVT injections and intraoperative or postoperative cataract surgery complications. Also no correlation was found between the number of injections or the time period between the last injection to the operation day to complication rate
