目的探讨白内障手术后囊袋扩张综合征的发生率和形态学变化，分析其临床特点和影响因素。记录人口统计学数据、术中眼科粘弹剂装置的使用、植入的人工透镜类型、眼轴长度和白色至白色角膜直径。术后1个月，进行了扩张Scheimpflug成像。患病率，形态学变化，这种syndrome的特征性临床表现进行了evaluated.ResultsUsing Scheimpflug成像，囊袋扩张综合征的患病率高，为26.8%（64/239），它是可能的，其形态学变化分为3种类型。与无综合征患者相比，有综合征患者的最佳矫正视力较差，满意度评分较低（分别为P= 0.041和P = 0.008）。虽然在我们的研究中使用的两种眼科粘性手术器械之间没有观察到该综合征的发生率有显著差异（P> 0.05），但植入4襻人工晶状体与该综合征的高患病率相关（比值比，2.07; 95%置信区间，1.05 - 4.07;P= 0.0346）。患有这种综合征的患者的AL显著延长（26.26 ± 2.84 mm）和白色至白色直径（12.02 ± 0.34）mm（AL：24.63 ± 2.89 mm，白-白色径：11.81 ± 0.32 mm; P= 0.0002和P <0.0001）。结论Scheimpflug成像显示囊袋扩张综合征的患病率很高，这些患者的视力结果普遍较差。眼内透镜的设计和尺寸的眼睛显着影响这种综合征的患病率。
PurposeTo investigate the prevalence and morphologic changes of capsular bag distention syndrome after cataract surgery using the Pentacam and to analyze its clinical characteristics and influencing factors.DesignRetrospective, cross-sectional study.MethodsClinical records of 239 consecutive patients who underwent cataract surgery were reviewed. Demographic data, use of intraoperative ophthalmic viscosurgical devices, type of intraocular lens implanted, axial length, and white-to-white corneal diameter were recorded. One month after surgery, dilated Scheimpflug imaging was performed. Prevalence, morphologic changes, and characteristic clinical findings of this syndrome were evaluated.ResultsUsing Scheimpflug imaging, the prevalence of capsular bag distention syndrome was high at 26.8% (64/239), and it was possible to classify its morphologic changes into 3 types. Patients with the syndrome had poorer best-corrected visual acuity and lower satisfaction scores than those without the syndrome (P= .041 andP= .008, respectively). Although there was no significant difference observed in rate of this syndrome between the 2 ophthalmic viscosurgical devices used in our study (P> .05), implantation of 4-haptic intraocular lenses was associated with a high prevalence of the syndrome (odds ratio, 2.07; 95% confidence interval, 1.05 to 4.07;P= .0346). Patients with this syndrome had significantly longer AL (26.26 ± 2.84 mm) and white-to-white diameter (12.02 ± 0.34 mm) than those without (AL, 24.63 ± 2.89 mm; white-to-white diameter, 11.81 ± 0.32 mm;P= .0002 andP< .0001, respectively).ConclusionsScheimpflug imaging revealed the prevalence of capsular bag distention syndrome to be high, and these patients generally had poorer visual outcomes. Intraocular lens design and dimensions of the eyes significantly influenced the prevalence of this syndrome.
