超声乳化术与现代囊外摘除术对硬核性白内障角膜内皮的影响

目的：探讨超声乳化术与现代囊外摘除术对硬核性白内障角膜内皮的影响。方法选择我院自2012年1月-2014年1月收治的44例硬核性白内障患者，随机分为观察组22例（28眼）与对照组22例（27眼），全部患者术前均予详细的全身及眼部检查，观察组患者行超声乳化技术治疗，对照组患者行现代囊外摘除术。结果治疗后，两组患者角膜内皮细胞密度、平均细胞面积、六角形细胞比与术前比较，差异具有显著性（P〈0.05）；观察组患者角膜内皮细胞密度、平均细胞面积、六角形细胞比及细胞丢失率与对照组比较，差异具有显著性（P〈0.05）；患者术后视力恢复情况比较，差异具有显著性（P〈0.05）；术后并发症发生比较，无显著性差异（P〉0.05）。结论超声乳化术可有效改善患者视力，适用于硬核性白内障患者的治疗。但超声乳化术对角膜内皮细胞的损伤程度高于现代囊外摘除术。

Analysis of modern phacoemulsification cataract extracapsular cataract extraction corneal endothelium impact on hard-core sexual

Objective To discuss the impact on modern phacoemulsification cataract extracapsular cataract extraction corneal endothelium. Methods Clinical data in our hospital from January 2012 to January 2014 were treated 44 cases of hard nuclear cataract patients,according to the random principle,all the patients were divided into observation group,22 cases （28 eyes） and control group, 22 cases （27 eyes）, all patients were given detailed preoperative systemic and ocular inspection, observation group were treated with phacoemulsification technique and control group were treated with the application of modern extracapsular cataract extraction. Results After treatment,corneal endothelial cell den-sity, mean cell area, hexagonal cells in two groups compared with the preoperative ratio, had a significant difference（P〈0.05）,corneal endothelial cell density, mean cell area, hexagonal cells and cell loss rate in the observation group compared with the control group had a significant difference （P〈0.05）, the recovery of visual acuity in patients com pared, there was a significant difference （P〈0.05）, the incidence of postoperative complications contrast, there was no significant difference（P〉0.05）. Conclusion Phacoemulsification can improve visual acuity for hard nuclear cataract patients. However,the extent of damage phacoemulsification on corneal endothelial cells is higher than that of modern extracapsular cataract extraction.
