羟丙基甲基纤维素是一种高纯度、吸水性比较强的多醣高分子聚合物。它具有较好的内聚性和滑润性,与角膜的屈光指数相一致,在眼内的pH值稳定,对光线照射不受影响。1945年Aron-Rosa对该物质的刺激性、过敏反应、房水排出时间等,用兔眼做了一系列试验。均证实没有细胞增殖、无毒性和过敏反应。70年代初,由于人工晶体置入术的发展,对羟两基甲基纤维素又开拓了新的用途。现将我院配制的2～3%溶液在眼科手术100例的应用情况报告如下: Hydroxypropyl methyl cellulose is a high purity, water-absorbing polysaccharide polymer. It has good cohesion and lubricity, consistent with corneal refractive index, pH in the eye stability, the light irradiation is not affected. 1945 Aron-Rosa on the substance irritation, allergic reactions, aqueous humor discharge time, a series of experiments with the rabbit eye. Confirmed no cell proliferation, non-toxic and allergic reactions. The early 70s, due to the development of intraocular lens implantation, hydroxy-2-methyl cellulose has opened up new uses. Now the preparation of our hospital 2 to 3% solution in the application of ophthalmic surgery 100 cases are reported as follows:
