Abstract:
Purpose:To analyze the incidence rate and risk factors of intraocular lens dislocation in South Korea from 2002 to 2020 using Health Insurance Review and Assessment Service data.
Methods:This study included 15% of patients aged > 40 years had pseudophakia or intraocular lens primary implantation codes during 2002-2020 (737,606 patients). The annual incidence rate and risk factors of intraocular lens dislocation during 2002-2020 were analyzed.
Results:The mean annual incidence rate of intraocular lens dislocation during 2002-2020 was 0.20 ± 0.7%. The annual incidence rate increased significantly from 0.17% in 2002 to 0.34% in 2020 (p < 0.001). The annual mean incidence rate for women was 0.1 ± 0.05%, and there was no increasing trend (p > 0.05). The annual mean incidence rate for men was 0.35 ± 0.13% and an increasing trend was found (p < 0.001). High myopia, uveitis, retinitis pigmentosa, glaucoma, pseudoexfoliative glaucoma and previous vitreoretinal surgery significantly increased the risk of intraocular lens dislocation (p < 0.001). Hemodialysis and hypertension were not significant risk factors (p > 0.05).
Conclusions:The mean annual incidence rate of intraocular lens dislocation in South Korea was 0.2 ± 0.7%, and it showed an increasing trend, among men. High myopia, uveitis, retinitis pigmentosa, glaucoma, pseudoexfoliative glaucoma and previous vitreoretinal surgery significantly increased the risk of intraocular lens dislocation.
