Abstract
Elderly patients who underwent cataract surgery showed lower prevalence and cumulative incidence rates of hip and vertebral fragility fractures than those who did not. Therefore, cataract surgery in elderly patients may reduce the incidence of hip and vertebral fragility fractures. PURPOSE: The purpose of this study was to compare the incidence rates of hip and vertebral fragility fractures between patients who underwent cataract surgery and those who did not, and to investigate the effect of cataract surgery on the incidence of fragility fracture in elderly population using nationwide claims data. METHODS: A total of 558,147 participants from the National Health Insurance Service - Senior cohort were included. The participants were set into the hip fracture group (507,651) and vertebral fracture group (507,899) depending on the type of fracture. RESULTS: The number of hip fractures that occurred in the non-cataract surgery (NC) group was 36,971 (9.9%), while 8850 (6.6%) hip fractures occurred in the cataract surgery (C) group. The number of vertebral fractures that occurred in the NC group was 38,689 (10.3%), while 10,112 (7.6%) vertebral fractures occurred in the C group (all p < .001). The hazard ratios of hip and vertebral fractures were 0.58 and 0.60 for the total population that had undergone cataract surgery (all p < .001). The cumulative incidence rates of both fractures in the cataract surgery group were significantly lower than those in the non-cataract surgery group during 10 years (all p < .0001). CONCLUSION: Elderly patients who underwent cataract surgery showed a lower prevalence of hip and vertebral fragility fractures than those who did not. In addition, the cumulative incidence rates of both fractures in the cataract surgery group were lower than those in the non-cataract surgery group. Therefore, cataract surgery in elderly patients may reduce the incidence of hip and vertebral fragility fractures.
