目的 :比较常用粘弹性物质在白内障手术中的应用。方法 :选常用粘弹性制剂透明质酸钠 (SH)、羟丙基甲基纤维素 (HPMC)和硫酸软骨素 (Viscoat)作为实验材料 ,经 15 0例(30 0眼 )白内障人工晶体值入术应用 ,观察其术中应用及术后效果。结果 :对眼内组织驱动性能 ,粘、弹性能 ,透明性及对内眼组织保护作用 ,SH最好 ,Viscoat次之 ,而HPMC较差。结论 :国产SH可取代进口同类产品 ,且效果很好 Objective: To compare the commonly used viscoelastic material in cataract surgery. Methods: The commonly used viscoelastic formulations of sodium hyaluronate (SH), hydroxypropyl methyl cellulose (HPMC) and chondroitin sulfate (Viscoat) were selected as the experimental materials. After 150 eyes (30 eyes) Application, observation of its intraoperative application and postoperative effects. Results: The driving performance, viscosity, elasticity, transparency and protection of intraocular tissue of eye tissue were the best, followed by Viscoat and inferior to HPMC. Conclusion: Domestic SH can replace imported similar products, and the effect is very good
