【摘要】 目的比较Nd:YAG激光乳化和超声乳化白内障摘出术对角膜内皮细胞密度、形态及角膜厚度的影响。方法选取9例(18眼)老年性白内障患者,双眼分别行Nd:YAG激光乳化和超声乳化白内障摘出术联合人工晶状体植入术,术后随访37个月,比较双眼视力、眼压、角膜内皮细胞计数以及角膜厚度等情况。结果术后37个月,Nd:YAG激光乳化眼角膜内皮细胞密度为(1715.4±627.9)mm-2,超声乳化眼角膜内皮细胞密度为(2330.7±426.5)mm-2,2组比较差异具有统计学意义(P<0.05);2组角膜内皮细胞六角形比例、角膜内皮细胞形态变异率和角膜厚度比较,差异均无统计学意义(均为P>0·05)。2组术后视力、眼压差异也均无统计学意义(均为P>0·05)。结论 Nd:YAG激光乳化白内障摘出术后远期角膜内皮细胞数明显减少,应慎重施行激光乳化白内障摘出术。更多还原

【Abstract】 Objective To compare the long-term effects on density,morphous of corneal endothelial cells and corneal thickness after Nd:YAG laser emulsification and phacoemulsification cataract surgery.Methods Nine senile patients(18 eyes) were performed cataract surgery.In each patient,one eye was performed Nd:YAG laser emulsification whereas the fellow was performed phacoemulsification.The number of corneal endothelial cells,corneal thickness,intraocular pressure and visual acuity were checked.The average follow-up time was 37 months.Results At 37 months after surgery,the average density of corneal endothelial cells in eyes with Nd:YAG laser emulsification and phacoemulsification were(1 715.4±627.9)mm-2 and(2 330.7±426.5)mm-2,respectively,there was statistical difference between two kinds of emulsification(P<0.05).There was no statistical difference in hexagonal corneal endothelial cell rate,aberration rate of corneal endothelial cells morphous,corneal thickness,intraocular pressure and visual acuity between two groups(all P>0.05).Conclusion The number of corneal endothelial cells after Nd:YAG laser emulsification is obviously decreased in the long-term observation,so laser emulsification should be carefully chosen.更多还原
