目的　探讨后房型人工晶状体（ＰＣＩＯＬ） 脱入玻璃体腔内及ＩＯＬ 再复位的手术方法。 方法　对５ 例ＰＣＩＯＬ脱入到玻璃体腔内经玻璃体切割取出及ＩＯＬ 睫状沟固定观察其手术疗效。 结果　５ 例患者ＩＯＬ 位置正中、稳固，视力均在０ ．３ 以上，最好视力０ ．８ 。 结论　ＩＯＬ 脱入玻璃体腔后，应尽早手术，玻璃体手术处理是惟一安全有效的方法，睫状沟缝线固定ＩＯＬ 定位要准确，不但可避免并发症的发生，还可使患者的视力得到明显的改善 Objective To investigate the surgical method of posterior chamber intraocular lens (PCIOL) removal into vitreous cavity and IOL reset. Methods 5 cases of PC  IOL into the vitreous cavity removed by vitrectomy and IOL ciliary sulcus fixation observed its curative effect. Results The IOL position was moderate, stable and visual acuity was 0 in 5 patients. 3 or more, the best visual acuity 0. 8. Conclusion IOL into the vitreous cavity should be as soon as possible after surgery, vitrectomy is the only safe and effective method, ciliary suture fixation IOL positioning should be accurate, not only to avoid complications, but also make the patient’s visual acuity was significantly improve
