A multicenter prospective trial was conducted comparing preoperative and postoperative endothelial cell counts in patients who had extracapsular cataract extraction with posterior chamber lens implantation or phacoemulsification and posterior chamber lens implantation. One hundred sixty six eyes received 2% hydroxypropyl methylcellulose (Occucoat) and 56 eyes received sodium hyaluronate (Healon). The average cell loss in the Occucoat group was 12.1%; in the Healon group it was 10% (P = NS). There was no significant difference between the two groups in intraocular pressure at 24 hours. In this study Occucoat was as effective in protecting the corneal endothelium as Healon.
进行了一项多中心前瞻性试验，比较了接受囊外白内障摘除联合后房型人工晶状体植入术或超声乳化白内障吸除联合后房型人工晶状体植入术患者术前和术后的内皮细胞计数。166只眼使用了2%羟丙基甲基纤维素（欧可维），56只眼使用了透明质酸钠（爱维）。欧可维组的平均细胞损失率为12.1%；爱维组为10%（P=无显著性差异）。两组在术后24小时的眼压无显著差异。在本研究中，欧可维在保护角膜内皮方面与爱维一样有效。
