评价高度近视韩国受试者白内障手术的临床特征和结局。我们回顾性分析了694例694眼接受白内障手术的患者的病历。病例组包括眼轴长度（AXL）≥26.00 mm的患者347例（347眼），对照组包括AXL在22.00 ~ 25.99 mm之间的患者347例（347眼）。我们比较了手术年龄、白内障类型、并存疾病、视力预后和并发症。病例组手术时的平均年龄为59.60 ± 12.28岁，对照组为67.47 ± 11.36岁。病例组有较大比例的核性白内障和后囊下白内障（PSC），分别为40.63%和26.22%，而对照组分别为25.07%和11.82%。术后矫正视力与AXL呈负相关（R2 = 0.172），严重的眼底镜检查结果与视力预后不良相关（p = 0.05）。病例组白内障术后视网膜脱离发生率为1.72%，对照组为0.28%。高度近视的眼睛往往比正常的眼睛更早地患上白内障，并且具有更高的共存疾病和并发症的患病率，例如视网膜脱离。核性白内障和PSC在高度近视组中更常见。视力预后差与眼轴长和视网膜近视变性有关。
To evaluate the clinical characteristics and outcomes of cataract surgery in highly myopic Korean subjects. We retrospectively reviewed the medical records of 694 eyes of 694 patients who underwent cataract surgery. The case group included 347 eyes of 347 patients whose axial lengths (AXL) were ≥26.00 mm, and the control group included 347 eyes of 347 patients with AXL between 22.00 and 25.99 mm. Cataract density was determined preoperatively using the Pentacam Scheimpflug imaging system. We compared age at operation, cataract type, coexisting disease, visual prognosis, and complications. The mean age at the time of the operation was 59.60 ± 12.28 years in the case group and 67.47 ± 11.36 years in the control group. The case group had a larger proportion of nuclear cataracts and posterior subcapsular cataracts (PSC), 40.63% and 26.22%, respectively, versus 25.07% and 11.82%, respectively, in the control group. Postoperative corrected visual acuity showed a negative correlation with AXL (R2 = 0.172), and severe funduscopic findings were related to poor visual prognosis (p = 0.05). The incidence of retinal detachment in the case group after cataract surgery was 1.72%, compared with 0.28% in the control group. Highly myopic eyes tend to develop cataracts earlier than normal eyes and to have a higher prevalence of coexisting disease and complications, such as retinal detachment. Nuclear cataracts and PSC were more common in the highly myopic group. Poor visual prognosis was associated with longer axial length and retinal myopic degeneration.
