Abstract
OBJECTIVE
To determine whether previous intravitreal injections are an independent risk factor for posterior capsular rupture (PCR) during cataract surgery after adjusting for known risk factors.
DESIGN
Single-centre medical records analysis of a population-based cohort at a university-based referral centre. A retrospective cohort study has been conducted with inclusion of cataract surgeries done from January 1, 2005 to December 31, 2020 at the Department of Ophthalmology, Medical University of Graz, Austria.
PARTICIPANTS
All consecutive cataract surgeries done in patients of at least 18 years of age from January 1, 2005 to December 31, 2020 have been included.
METHODS
Association between previous intravitreal injections and PCR rates has been analysed through univariable and multivariable generalized estimating equations (GEE). Other investigated risk factors were age, combined surgery, pseudoexfoliation, surgeon's experience, and type of cataract surgery.
RESULTS
A statistically significant higher rate of posterior capsular rupture during cataract surgery has been found in patients with previous intravitreal therapy compared with patients with no history of intravitreal therapy (OR 1.27, 95% CI 1.10-1.46, p = 0.008). However, after adjusting for confounding risk factors, no statistically significant effect was seen (OR 1.04, 95% CI 0.89-1.21, p = 0.664).
CONCLUSION
We found no association between history of intravitreal injections and PCR during cataract surgery after adjusting for known risk factors. Further studies upon interactions between history of intravitreal injections and known risk factors for PCR, especially pseudoexfoliation, are needed.
