Acrysof与Centerflex折叠一片式人工晶状体植入术临床观察

The clinical observation of foldable single-piece IOL of Acrysof and Centerflex

目的 观察美国 Acrysof与英国 Centerflex折叠一片式人工晶状体在白内障超声乳化手术植入后的临床效果。方法 随机选择 132例老年性白内障患者行白内障超声乳化手术 ,术中 6 2例 (6 2只眼 )植入美国Acrysof折叠一片式人工晶状体 ,70例 (70只眼 )植入英国 Centerflex折叠一片式人工晶状体 ,观察术中植入情况、人工晶状体的位置及稳定性和术后角膜反应、前房反应、术后视力、角膜内皮细胞密度、后囊膜增生情况等 ,随访时间 3个月。结果 两种人工晶状体植入术后矫正视力均良好 ,眼内反应轻 ,晶状体植入囊袋内位置稳定 ,未见明显后囊膜混浊及增生 ,角膜内皮细胞密度术后与术前比较均无显著差异。结论 美国 Acrysof与英国 Centerflex折叠一片式人工晶状体在白内障超声乳化手术后植入效果满意 ,值得临床推广应用。

Objectives To observe the clinical effects upon implanting of foldable single-piece IOL of American Acrysof and English Centerflex in the cataract phacoemulsification. Methods 132 age-related cataract patients were randomly chosen to operate for phacoemulsification. In which, 62 patients were implanted with foldable single-piece IOLs of American Acrysof and 70 patients were implanted with foldable single-piece IOLs of English Centerflex. During the operation, the implanted condition, IOL location and stability were observed. The corneal reaction, anterior chamber reaction, visual acuity, corneal endothelial cells' density, and posterior capsule proliferation were also observed. The follow up time was three months. Results The corrected visual acuity effect was satisfactory, the intraocular reaction was weak, and IOLs location was stable in the capsule of the two IOLs after the operation. The turbid and proliferation of posterior capsule were not obvious. The difference of corneal endothelial cells' density between pre-operation and post-operation was not distinct. Conclusion The clinical effects upon foldable single-piece IOL of American Acrysof and English Centerflex were satisfied after the cataract phacoemulsification^And it was worth clinical promoting.
