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.
