Abstract

Posterior capsule opacification (PCO), a common complication after cataract surgery, impacts a patient's long-term visual quality to various degrees. Although a neodymium:yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy is a very effective treatment, it may lead to a serial of complications. Accordingly, the search for simple, safe, and effective methods to prevent PCO has received widespread attention. Various researchers are committed to the interdisciplinary collaboration between medicine and engineering fields, such as functionalizing the surface of the intraocular lens (IOL) via supercritical fluid impregnation, coating the surface of the IOL, high-concentration drug immersion, and application of a drug delivery system, to effectively reduce the incidence and severity of PCO.

摘要

后发性白内障(PCO)是白内障手术后的一种常见并发症,会对患者的长期视觉质量产生不同程度的影响。虽然钕:钇铝石榴石(Nd:YAG)激光后囊切开术是一种非常有效的治疗方法,但它可能会导致一系列并发症。因此,寻找简单、安全、有效的方法来预防 PCO 已经引起了广泛关注。许多研究人员致力于医学和工程领域之间的交叉学科合作,例如通过超临界流体浸渍对人工晶状体(IOL)的表面进行功能化、IOL 表面涂层、高浓度药物浸泡以及药物输送系统的应用,以有效降低 PCO 的发生率和严重程度。
