外伤性晶状体不全脱位人工晶状体单襻缝合术

Vitreolensectomy combined with intraocular lens implantation by single haptic scleral suturing forthe traumatic lens subluxation

目的评价晶状体玻璃体切除联合人工晶状体单襻缝合固定术治疗外伤性晶状体不全脱位的效果。方法回顾性分析外伤性晶状体不全脱位18例（18只眼）的临床资料。患者均行保留部分晶状体囊的玻璃体晶状体切除联合人工晶状体单襻缝线固定术。术后随访6～18个月，观察人工晶状体位置、眼压、视力及并发症等。结果术后视力显著提高（P=0．000），眼压稳定，人工晶状体位置良好，无人工晶状体相关并发症。结论保留部分晶状体囊的晶状体玻璃体切除联合后房型人工晶状体单襻巩膜缝线固定术是治疗外伤性晶状体不全脱位的可行方式。

Objective To evaluate the efficacy of vitreolensectomy combined with posterior chamber intraocular lens （PCIOL） implantation by single haptic scleral suturing for the treatment of traumatic lens subluxation. Methods The data of 18 eyes of 18 cases with traumatic lens subluxation were collected and analyzed retrospectively. All cases underwent vitreolensectomy retaining partial capsule and PCIOL were fixated by single haptic scleral suturing and retained capsular. The follow-up time was 6-18 months. Position of PCIOL, BCVA, intraocular pressure, and complications were observed and retrospectively analyzed. Results Post-operative BCVA was increased significantly （P = 0. 000）. Post-operative intraocular pressure was stable and the position of IOL was steady. There was no complication associated with IOL. Conclusion Vitreolensectomy retaining partial capsule combined with IOL implantation by single haptic scleral suturing is a practicable and safe procedure for traumatic lens subluxation.
