A patient who had been asymptomatic following extracapsular cataract extraction with posterior capsule rupture and anterior chamber lens implantation presented 18 months postoperatively with iritis and erosion of the superior haptic through the site of the cataract wound. At the time of explantation, it was seen that the anterior chamber lens had been inserted in a backward manner with the anterior face of the lens placed posteriorly. The resultant lens vaulting placed the superior haptic in the same plane as the cataract wound. Whether the superior haptic had initially been incorporated in the surgical wound or had eroded through the eye wall from the anterior chamber, the backward placement of the anterior chamber lens likely played a role in the development of haptic externalization.
一位患者在行囊外白内障摘除术、后囊破裂及前房型人工晶状体植入术后一直无症状，但在术后18个月出现了虹膜炎，且人工晶状体上襻通过白内障切口部位发生侵蚀。在取出人工晶状体时，发现前房型人工晶状体被反向植入，晶状体的前表面朝后。由此产生的晶状体拱起使上襻与白内障切口处于同一平面。无论上襻最初是被包埋在手术切口中，还是从前房穿过眼壁发生侵蚀，前房型人工晶状体的反向植入可能在上襻外露的发生过程中起到了作用。
