We present the case of a patient who experienced recurrent episodes of blurry vision and eye pain after uneventful cataract extraction and in-the-bag intraocular lens (IOL) implantation. Examination revealed a microhyphema and signs of pigment dispersion. Iris transillumination was seen overlying areas where the IOL optic was not covered by the anterior capsule. Anterior segment optical coherence tomography confirmed iris indentation by the IOL optic, which was alleviated by performing laser peripheral iridotomy. This case shows that IOLs in the capsular bag can erode the posterior surface of the iris and that an adequately sized capsulorhexis should be performed to ensure anterior capsule coverage. Laser peripheral iridotomy should be considered when significant posterior iris bowing is observed.
我们报告了一例患者,该患者在白内障摘除及囊袋内人工晶状体(IOL)植入术后视力模糊和眼痛反复发作。检查发现有微量前房积血和色素播散的体征。在人工晶状体光学部未被前囊膜覆盖的区域可见虹膜透照。前段光学相干断层扫描证实人工晶状体光学部对虹膜有压痕,通过激光周边虹膜切开术可缓解这种情况。该病例表明,囊袋内的人工晶状体可侵蚀虹膜后表面,应进行足够大小的连续环形撕囊以确保前囊膜覆盖。当观察到明显的虹膜后凸时,应考虑激光周边虹膜切开术。
