To analyze the latest annual trends in immediate sequential bilateral cataract surgery (ISBCS) and delayed sequential bilateral cataract surgery (DSBCS) among patients with bilateral cataracts in Korea, and to identify the factors influencing the choice of surgery and the outcomes associated with ISBCS and DSBCS.
This retrospective, nationwide cohort study included all patients aged 65 and older who were covered by the Korean National Health Insurance and underwent ISBCS or DSBCS from 2016 to 2021. The study recorded yearly numbers of ISBCS and DSBCS procedures, the interval between surgeries in DSBCS cases, patient demographics, types of implanted intraocular lenses (IOLs), and the incidence of cystoid macular edema and endophthalmitis following ISBCS or DSBCS.
A total of 50 878 (7.2%) patients underwent ISBCS, and 658 609 (92.8%) patients underwent DSBCS. ISBCS cases more than doubled in 2020 (7902) from 2019 (3703) before increasing even more significantly in number in 2021 (33 645). Age, hospital size, ocular and systemic comorbidities, type of IOL, and calendar year were associated with receiving ISBCS. In 2020 alone, the incidence of postoperative endophthalmitis among ISBCS patients was significantly higher (1.39 per 1000 procedures) than among DSBCS patients (0.40 per 1000 procedures; P = 0.001).
The number of patients undergoing ISBCS for bilateral cataracts increased annually, particularly after the onset of the COVID-19 pandemic in Korea in 2020. However, this significant rise in ISBCS also led to a surge in the incidence of postoperative endophthalmitis in 2020.
分析韩国双侧白内障患者即刻序贯双侧白内障手术（ISBCS）和延迟序贯双侧白内障手术（DSBCS）的最新年度趋势，并确定影响手术选择的因素以及与ISBCS和DSBCS相关的手术结果。
这项全国性回顾性队列研究纳入了所有65岁及以上、参加韩国国民健康保险并在2016年至2021年期间接受ISBCS或DSBCS手术的患者。该研究记录了ISBCS和DSBCS手术的年度数量、DSBCS病例手术间隔时间、患者人口统计学特征、植入人工晶状体（IOL）类型以及ISBCS或DSBCS术后黄斑囊样水肿和眼内炎的发生率。
共有50878例（7.2%）患者接受了ISBCS，658609例（92.8%）患者接受了DSBCS。2020年ISBCS病例数（7902例）比2019年（3703例）增加了一倍多，2021年数量进一步显著增加（33645例）。年龄、医院规模、眼部和全身合并症、IOL类型以及年份与接受ISBCS有关。仅在2020年，ISBCS患者术后眼内炎发生率（每1000例手术1.39例）显著高于DSBCS患者（每1000例手术0.40例；P = 0.001）。
双侧白内障接受ISBCS手术的患者数量逐年增加，尤其是在2020年韩国COVID-19疫情爆发之后。然而，2020年ISBCS的显著增加也导致术后眼内炎发生率激增。
