In two patients secondary cataracts developed after pars plana vitrectomy. In both cases the lens was removed from the pars plana, and the anterior capsule was kept intact. In one patient a posterior chamber lens was placed in the ciliary sulcus 3 months after the lens had been removed, and in the other patient a posterior chamber lens was implanted intraoperatively after pars plana lensectomy and vitrectomy. Improved visual results were obtained in both cases, and there was no evidence of rubeosis or elevated intraocular pressure. In selected cases preservation of the anterior capsule may be important to implant posterior chamber lenses in eyes requiring pars plana lensectomy and vitrectomy. To our knowledge this technique has not previously been reported.
两名患者在玻璃体切割术后发生了后发性白内障。在这两个病例中，晶状体均从睫状体扁平部取出，前囊膜保持完整。其中一名患者在晶状体摘除3个月后，将后房型人工晶状体植入睫状沟；另一名患者在经睫状体扁平部晶状体切除及玻璃体切除术中植入了后房型人工晶状体。两个病例均获得了改善的视力结果，且没有虹膜红变或眼压升高的迹象。在某些特定病例中，对于需要进行睫状体扁平部晶状体切除及玻璃体切除术的眼睛，保留前囊膜对于植入后房型人工晶状体可能很重要。据我们所知，此前尚未有关于该技术的报道。
