目的：探讨四点固定人工晶状体悬吊术在无囊膜的人工晶状体植入、先天悬韧带断裂致晶状体完全脱位、外伤性白内障及后囊破裂后无囊膜支撑等需行人工晶状体悬吊术中的临床观察。

方法：回顾性分析2012-05/2014-05期间我院采用四点固定人工晶状体悬吊术患者31例32眼，对其术后视力、角膜散光度、术中及术后并发症方面进行分析。

结果：术后随访6mo～1a，矫正视力>0.5者12眼(38%)； 0.1≤矫正视力≤0.5者18 眼(56%)； <0.1者2眼(6%)； 角膜散光度平均为0.97±0.35D； 术中及术后出现睫状体穿刺口出血、人工晶状体偏位、倾斜、角膜水肿、悬吊线松弛断裂等的几率降低。

结论：该术式为无囊膜支撑的人工晶状体植入而设计，其理念改变了以往悬吊人工晶状体植入术后存在偏位、倾斜及缝线割裂等并发症的发生率大大降低，它符合人眼的生理特点，是目前人工晶状体悬吊术手术方式中稳定性最好、术中及术后并发症最少、术后视力恢复最佳及术后角膜散光度最小的手术方式，且四点固定人工晶状体悬吊术的设计已获得了中国实用转型专利。

AIM: To discuss the four-fixable intraocular lens(IOL)suspensory in the absence of capsular intraocular lens implantation, suspensory ligament rupture caused by congenital dislocation of the lens, traumatic cataract and posterior capsular rupture without capsular support, which need to line hanging IOL for intraoperative clinical observation.

METHODS: The 31 cases(32 eyes)who were accepted the four-fixable IOL suspensory from May 2012 to May 2014 in our hospital were retrospectively analyzed. The postoperative visual acuity, corneal astigmatism, intraoperative and postoperative complications were comprehensively analyzed.

RESULTS: Patients were followed up 6mo～1a, corrected visual acuity >0.5(12 eyes, 38%), 0.1～0.5(18 eyes, 56%), and <0.1(2 eyes, 6%); corneal astigmatism averaged 0.97±0.35D; the chance of intraoperative and postoperative bleeding puncture ciliary body, IOL positional deviation, corneal edema, hanging slack line breaks were reduced.

CONCLUSION: It is designed to support non-capsular IOL implantation and design, and the concept of changing the past presence of suspended dislocated IOL implantation surgery, positional deviation and, sutures and other complications split the incidence is greatly reduced. It is consistent with the physiological characteristics of the human eye, and it is the IOL surgical sling best stability, intraoperative and postoperative complications, the best visual acuity and corneal astigmatism minimal surgical approachat least, and the four-point suspension suture fixation of IOL is designed to obtain a practical transformation of Chinese patent.
