任何手术都不可避免地会造成机体的损伤。我们的目标是尽可能地减少损伤,以手术对角膜的损伤而言,角膜上皮的损伤并非只是细胞遭到破坏,于此同时,伤口会释放出几种酶剂,如蛋白分解酶、胶原酶及多糖酶等等。由于这些反应,可以促使角膜产生新生血管,影响术后视力恢复。再如做白内障手术时,如果角膜缝合不牢,在前房侧伤口有裂隙,此时的成纤维细胞几乎全由浅层巩膜而来,故伤口愈合较难。由此可见手术对角膜的损伤是一种常见并应引起足够重视的问题,下面就根据有关文献及临床所见做一综述。 Any operation will inevitably cause damage to the body. Our goal is to minimize damage to the corneal damage to the surgery, the damage to the corneal epithelium is not just the cells were destroyed, at the same time, the wound will release several enzymes, such as proteolytic enzymes, collagenase And polysaccharides enzymes and so on. As a result of these reactions, can promote corneal neovascularization, affecting postoperative visual acuity. Another example of cataract surgery, if the corneal suture is not strong, there are cracks in the anterior chamber side of the wound, fibroblasts at this time almost entirely from the superficial sclera, so the wound healing more difficult. This shows that surgery on the corneal damage is a common and should cause enough attention to the problem, the following is based on the literature and clinical observations made a review.
