目的:探讨玻璃体切割及缝双襻术后人工晶状体脱落原因,及其对再次手术的启示。方法:收集2005-06/2007-09在我科住院手术治疗的9例玻璃体切割及缝襻术后人工晶状体脱落患者,予局部麻醉后再次人工晶状体缝襻手术。我们选用无降解的缝线,在不影响光学区前提下尽可能的保留原人工晶状体,再次缝襻时尽量做到对称、无张力。结果:随访3～5a,术后视力比术前明显提高,人工晶状体稳定。结论:缝襻术后,人工晶状体脱落原因有多个:外力、人工晶状体材质、缝襻线降解、缝线存在张力等,尽可能避免这些因素,是可以做到小创伤手术,再次获得较好视力,达到稳定的治疗效果。

·AIM:To investigate the reasons and enlightenment for re-operation of intraocular lens(IOL)off after vitrectomy and double-loop suture.·METHODS:From June 2005 to September 2007,9 patients with IOL off after vitrectomy and loop suture were reoperated with loop suture of IOL under local anesthesia.Non-degradable sutures were used,without affecting the optical zone to retain the original IOL as much as possible,the loop was sutured again symmetrically and no tension as far as possible.·RESULTS:The results were followed up for 3-5 years.Compared with preoperative,visual acuity was significantly improved and IOL was stable.·CONCLUSION:There are several reasons for IOL off after loop suture:external force,IOL material,loop suture degradation,thread tension.By avoiding these factors as much as possible,a small invasive surgery can be done again to obtain better visual acuity and stabilize the therapeutic effect.·
