Risk model for intraoperative complication during cataract surgery based on data from 900 000 eyes : previous intravitreal injection is a risk factor
(2022) In British Journal of Ophthalmology 106(10). p.1373-1379- Abstract
BACKGROUND/AIMS: The aim of this study was to develop a risk model for intraoperative complication (IC) during cataract surgery, defined as posterior capsule rupture and/or zonular dehiscence, and to include previous intravitreal therapy (pIVT) in the model.
METHODS: This retrospective register-based study covered patients reported to the Swedish National Cataract Register (SNCR) between 1 January 2010 and 30 June 2018. Odds ratios (ORs) were used to quantify association strength of each variable with IC. Data from the SNCR were cross referenced with the Swedish Macula Register to include data on pIVT. Variables statistically significant in the univariate analyses (p<0.05) were included in a multivariate logistic regression... (More)

METHODS: This retrospective register-based study covered patients reported to the Swedish National Cataract Register (SNCR) between 1 January 2010 and 30 June 2018. Odds ratios (ORs) were used to quantify association strength of each variable with IC. Data from the SNCR were cross referenced with the Swedish Macula Register to include data on pIVT. Variables statistically significant in the univariate analyses (p<0.05) were included in a multivariate logistic regression model.
RESULTS: The inclusion criteria were met by 907 499 eyes. The overall rate of IC was 0.86%. Variables significantly associated with IC were best corrected visual acuity ≥1.0 LogMAR (OR (adjusted): 1.75, p<0.001), age ≥90 years (OR: 1.25, p<0.001), male sex (OR: 1.09, p<0.01), pseudoexfoliation (OR: 1.33, p<0.001), glaucoma (OR: 1.11, p<0.05), diabetic retinopathy (OR: 1.35, p<0.001), pIVT (OR: 1.45, p<0.05), surgeon's experience <600 surgeries (OR: 2.77, p<0.001), use of rhexis hooks (OR: 6.14, p<0.001), blue staining (OR: 1.87, p<0.001) and mechanical pupil dilation (OR: 1.52, p<0.001).
CONCLUSION: The risk model can be used in the preoperative setting to predict the probability of IC, to facilitate planning of surgery and improving patient communication. Patients who have undergone intravitreal therapy prior to cataract surgery have an increased risk of IC during cataract surgery.
