목적 : To investigate the incidence of corneal transplantation and identify rates and risk factors of repeated corneal transplantation in South Korea. 방법 : This is a retrospective population-based study using the Korean National Health Insurance System. Among the entire South Korean population, we included those who underwent keratoplasty between 2006 and 2016, and analyzed the annual incidence of keratoplasty and demographics of the subjects. The incidence rate of repeated keratoplasty after the first operation was calculated according to risk factors (age, sex, income, surgical method, surgical etiology, and major systemic diseases). Cox regression analysis was employed to evaluate hazard ratios of those risk factors on repeated keratoplasty. 결과 : A total of 9,452 cases of corneal transplantation occurred from January 2006 to December 2016. The average annual incidence of corneal transplantations of 1.694 per 100,000 people was steady throughout the study period. The average incidence of repeated keratoplasty among those who underwent corneal transplantation at least once was 43.24 per 1,000 person-years. Males had a greater incidence of repeated keratoplasty compared to females. The age group from 20 to 39 years demonstrated the lowest incidence of repeated keratoplasty. Keratoconus had the lowest incidence of repeated keratopalsty. 결론 : We report a nationwide, population-based study highlighting trends in keratoplasty and repeated keratoplasty in South Korea. This study may provide a better understanding of corneal diseases, help predict disease burden, and plan health care systems accordingly in South Korea. |
