摘要 目的探讨囊膜拉钩联合可缝合晶状体囊袋张力环在中重度晶状体半脱位治疗中的应用效果及注意问题。设计回顾性病例系列。研究对象2009年1月至2011年1月北京英智眼科医院治疗的15例(19眼)脱位范围135°~225°的中重度晶状体半脱位患者。方法患者在囊膜拉钩的辅助下行白内障超声乳化吸出折叠人工晶状体(IOL)植入术中同时植入可缝合囊袋张力环。术前观察晶状体脱位的范围及方位。术后平均随访(16.4±4.8)个月。测量视力、屈光状态、眼压,裂隙灯检查了解IOL位置,有无后发障、玻璃体疝等,UBM检查张力环位置。主要指标视力、并发症。结果 19眼(100%)均成功植入可缝合囊袋张力环。最后一次随访时视力均有不同程度提高。随访期间未见IOL明显偏位、眼压升高、张力环嵌顿、后发障及玻璃体疝等并发症。结论囊膜拉钩联合可缝合囊袋张力环植入可作为中重度晶状体半脱位者施行原位超声乳化白内障吸出折叠IOL植入术的有效辅助手段,能提高手术安全性及成功率,可维持术后囊袋长期稳定性。 To investigate the efficacy and safety of capsular hooks and modified capsular tension rings (MCTR) fbr the treatment of moderate to severe lens subluxation during phacoemulcification with intraocular lens (IOL) implantation. Design Retrospective case series. Participants 15 cases (19 eyes) of moderate to severe lens subluxation in which range of lens dislocation was from 135° to 225° in Beijing Intech Eye Hospital from January 2009 to January 2011. Methods Data were collected from total 19 eyes of 15 patients with moderate to severe lens suhluxation, who received the phacoemulsification and IOL implantation in the assistance of cap sular hooks and MCTR. The range and location of lens dislocation were observed preoperatively. Visual acuity, refractive power, intraocular pressure and anterior segment of the eyes were observed postoperatively. The average followup period was 16.4_+4.8 months. Main Outcome Measures Visual acuity, complications. Results The MCTR was implanted successfully in all 19 eyes (100%). At the last followup, visual acuity improved in all 19 eyes with no complications such as IOL asymmetry, high intraocular pressure, MCTR incarceration, serious posterior capsular opacification or vitreous hernia. Conclusion The capsular hooks and modified capsular tension rings are helpful for the treatment of moderate to severe subluxated lens during phacoemulsification. It can prevent from occurring of intraocular lens decentration and decrease the surgical complications. (Ophthalmol CHN, 2012, 21: 52-55)
