透镜植入术现在是一种非常成功的手术。尽管后房型人工晶状体的5 - 10年随访不完整，但并发症发生率似乎与其他透镜类型一样低或更低。我们提出一个例外：一个地球仪的临床病理学分析，摘除术后4年，尽管顺利植入后房透镜，发展成新生血管性青光眼。显微镜研究提示了这种罕见并发症的几种机制，包括普理灵环深入睫状体、眼前节缺血和血-房水屏障破坏。扫描显微镜显示，这个深深嵌入的环开裂，我们解释为可能的应力开裂和/或氧化的发现。现代镜片中使用的更灵活的环可以减少深度侵蚀的机会。在囊袋中植入袢可最大限度地降低糜烂和袢降解的危险。患者应长期随访，以识别和治疗这些罕见的，但潜在的灾难性并发症。
Lens implantation is now a highly successful operation. Although follow-up over 5 to 10 years with posterior chamber lenses is incomplete, the complication rate appears to be as low or lower than other lens styles. We present an exception: a clinicopathologic analysis of a globe, enucleated 4 years postoperatively, which in spite of uneventful implantation of a posterior chamber lens, developed neovascular glaucoma. Microscopic studies suggest several mechanisms for this rare complication including deep erosion of a prolene loop into the ciliary body, anterior segment ischemia, and breakdown of the blood-aqueous barrier. Scanning microscopy showed cracking of this deeply embedded loop, a finding we interpret as possible stress cracking and/or oxidation. The more flexible loops now used in modern lenses may decrease the chance of deep erosion. Implantation of a loop in the capsular bag may minimize the danger of both erosion and loop degradation. Patients should be followed long-term in order to recognize and treat these rare, but potentially disastrous complications.
