近几十年内,由于显微手术的推广应用,涉及角膜切口的眼科手术已发生了革命性的进展。同时,对缝线材料及缝合方法的改进也提出了更高的要求。分析现今常规缝线材料及缝合方法对角膜伤口愈合的影响,寻求更理想的缝线是一个值得重视的问题。一、角膜缝线的现状及理想缝线的标准外科手术缝合法至少已有四千年的历史,直至1940年,缝线主要取自天然材料,如棉线、亚麻线、丝线及肠线。50年代,随着高分子化学的飞速发展,出现了人工合成纤维,其中一些纤维用作手术缝线,如尼龙、聚乙烯、涤纶及聚丙烯。用于角膜伤口缝合的有:铬制肠线、胶原、尼龙、丝线、聚丙烯、聚乙二醇酸及Polyglactin
In recent decades, due to the popularization and application of microsurgery, eye surgery involving corneal incision has undergone a revolutionary progress. At the same time, the suture material and sewing methods to improve the proposed higher requirements. Analysis of the current suture material and suture methods on the impact of corneal wound healing, to find a more ideal suture is a problem worthy of attention. First, the status of corneal suture and the ideal standard suture surgical suture law at least four thousand years of history, until 1940, the suture is mainly taken from natural materials such as cotton, linen, silk and catgut. In the 1950s, with the rapid development of polymer chemistry, synthetic fibers appeared, some of which were used as surgical sutures, such as nylon, polyethylene, polyester and polypropylene. For corneal wound suture are: catgut, chromium, collagen, nylon, silk, polypropylene, polyglycolic acid and Polyglactin
