一、什么叫人工晶状体?人工晶状体是应用人工合成材料,如聚甲基丙烯酸甲脂(PM-MA)、硅胶、水凝胶等制成的一种特殊透镜。这些材料具有重量轻,光学性能高,无抗原性、致炎性、致癌性和生物降解等特性。它的形状、透光率、屈光力和功能类似于人的晶状体。白内障摘除后将此透镜植入眼内来替代原来的晶状体,使物体像能聚集在视网膜上,也就能看清周围的景物了。 First, what is an intraocular lens? IOL is the use of synthetic materials, such as polymethyl methacrylate (PM-MA), silica gel, hydrogel and other special lens made of a. These materials are lightweight, have high optical properties, are non-antigenic, proinflammatory, carcinogenic and biodegradable. Its shape, light transmittance, refractive power and function similar to the human lens. After the cataract removal, the lens is implanted in the eye to replace the original lens, allowing the object to gather on the retina and also to see the surrounding scene.
