Purpose

To study which factors influence the time between first- and second-eye cataract surgery, and to investigate the 2010 - 2019 trends in immediate sequential bilateral cataract surgery (ISBCS) and time interval of delayed sequential bilateral cataract surgery (DSBCS).

Setting

Departments affiliated with the Swedish National Cataract Register (NCR).

Methods

Since 2010 the NCR contains social security number for all cataract surgery cases, meaning that the procedure of both eyes for each patient can be identified in the database. In this study all cases with both-eye surgery were identified. The duration between first- and second-eye surgery were analysed and its relation to clinical parameters including type of care provider (private- or community-based) and region.

Results

The database contains 422,300 bilateral cataract extractions , of which 54,194 were ISBCS and 368,106 DSBCS. ISBCS procedures increased from 4% in 2010 to 15.9% in 2019 (p<0.001, ANOVA). A higher proportion of ISBCS was related to female gender, less ocular comorbidity, younger age, better preoperative visual acuity, and private care provider. The median time interval between first- and second-eye surgery in DSBCS was 61 days, decreasing from 108 days in 2010 to 27 days in 2019 (p<0.001, ANOVA). Shorter time interval was related to female gender, younger age, no surgical complications in first eye, less ocular co-morbidity, and private-run provider. The variation between regions was considerable for both ISBCS and DSBCS.

Conclusions

The frequency of ISBCS has increased significantly over the study period. The time interval between first- and second-eye surgery in DSBCS has decreased significantly over the study period. Many clinical parameters including sex and age are related to the change. This is also true for type of provider. The variation between regions is considerable which means that access to bilateral cataract surgery is dependent on domestic address.
