目前近视发病率逐年上升。一直以来眼科医生通过准分子激光手术来矫正低、中度近视,然而此种手术对于角膜偏薄、圆锥角膜以及高度近视等部分患者的治疗存在局限性。1993年,瑞士STAAR公司生产了一种可植入式接触镜( ilplantable collaler lens, ICL),植入到后房睫状沟中,用来矫正屈光不正。经过设计的不断改进,ICL已经逐渐成为目前治疗中、高度近视的有效手术方式。虽然其安全性已被证实,但仍有文献报道, ICL植入术后人工晶状体的位置会发生偏位及旋转,导致视力下降,严重者产生继发性青光眼,前囊下白内障等并发症。我们针对ICL术后位置异常进行综述。%Recently, the incidence of myopia increases year by year. The effectiveness of refractive surgery for the correction of ametropia is widely recognized with rapid development of ophthalmic microsurgery. The laser in situ keratomileusis ( LASlK ) has been accepted as a regular refractive surgery technique to correct mild and moderate myopia. However, it shows inadequacy in ability to correct high refractive errors, and in patients with thin cornea and keratoconus. ln 1993, Staar Surgical ( A. G. Nidau) introduced a modified intraocular collamer lens ( lCL ) for the correction of high myopia, which emerged as a safe and effective operation for moderate or high myopia gradually. Although it has already been proved that lCL has safety and efficacy for the correction of high myopia, several studies reported dislocation and rotation of lCL after implantation, which led decreased vision and poor satisfaction. ln severe cases, secondary glaucoma, anterior subcapsular cataract happened consequentially. These potential complications have drawn more and more attention by the majority of physicians and scholars. This paper aims to discuss the potential cause of shift and rotation of lCLs after implantation.
