To investigate the effect of prior intravitreal injections on risk of posterior capsule rupture (PCR) during cataract surgery.
Retrospective case series, single centre.
Electronic medical records were used to study all cataract surgery procedures performed by a single experienced surgeon between March 2014 and June 2016 in single centre. Variables included as possible risk indicators for PCR were age, sex, number of previous intravitreal injections, and indication for intravitreal therapy.
In total, 345 cataract surgery procedures were undertaken over the study period, of which 35 (10%) were in eyes with previous intravitreal injection(s). PCR occurred in 45 (13%) eyes. The number of injections was 4 or less in 8% of patients, between 5 and 9 in 3%, 10 or more in 1%. Prior intravitreal injection, the number of prior injections, indication for injections, sex or age was not associated with increased risk of PCR (p>0.05).
The results in this study show that previous intravitreal injection, number of previous injections or indication for injections is not affect PCR risk. It may be considered that the surgeon's experience is the key predictor factor in the PCR. Further investigation is required to determine the cause behind the increased PCR risk.
