角膜移植术后白内障应用扭动模式超声乳化吸出术治疗分析

目的观察扭动模式超声乳化白内障吸出术（PKP）治疗角膜移植术后硬核白内障的安全性和效果。方法回顾性分析2009年3月至2009年10月在我院眼科住院行白内障超声乳化吸除术的PKP患者28例（32只眼）临床资料。患者PKP术后11个月至8年,平均3.6年;根据晶状体核硬度分级,分别将28例（32只眼）并发Ⅲ级以上硬核白内障患者随机分为A、B两组,其中男12例（14只眼）,女16例（18只眼）。A组16只眼行常规超声乳化白内障吸出术,B组16只眼行扭动模式超声乳化白内障吸出术。观察术中前房稳定性、能量释放及时间,并比较术后第1天、3天、1周、2周角膜水肿及内皮细胞的变化及手术前后视力情况。结果术中B组前房稳定性优于A组（P〈0.05）;术中能量使用及超声时间明显少于A组,术后第1天、第7天B组角膜水肿情况明显轻于A组（P〈0.05）;术后第1天、第7天B组视力恢复明显优于A组（P〈0.05）。结论扭动模式超声乳化白内障吸出术是一种安全、高效、疗效好的手术方式,尤其对于硬核白内障的处理,优于传统超声乳化白内障吸出术。

Ozil phacoemulsification in cataract surgery after corneal transplantation analysis of application

Objective To observe the Ozil out of phacoemulsification corneal transplant surgery cataract after hard-core safety and effectiveness.Methods A retrospective study from March 2009 to October 2009 was hospitalized in our hospital eye cataract extraction in patients undergoing penetrating keratoplasty in 28 cases;keratoplasty 11 months to 8 years,with an average of 3.6 years;under the lens nuclear hardness grade,respectively,will be taken by 28 patients（32 eyes） with complicated or above grade Ⅲ in patients with hard-core cataract surgery using phacoemulsification Zhai,were randomly divided into A,B groups in patients with cataract surgery,28 cases（32）,where M 12 cases（14）,female 16 cases（18） ;in which A group of 16 line routine phacoemulsification cataract surgery,B group of 16 lines Ozil twist phacoemulsification cataract surgery.Intraoperative anterior chamber stability,energy release and time,and compare the postoperative 1d,3d,1w,2w observation of corneal edema and endothelial cells in small CEC） of the changes in visual acuity before andafter surgery the situation.Results The intraoperative anterior chamber stability of the B group is better than A group（P 0.05） ;intraoperative ultrasonic time of energy use and significantly less than the A group,after the first 1d,7 d B Group corneal edema was obviously lighter than A group（P = 0.05） ;postoperative 1d,7 d B group visual acuity better than A group（P 0.05）.Conclusion Twist phacoemulsification cataract surgery is a safe,efficient,good surgical efficacy,especially for hard-core cataract treatment,superior to the traditional phacoemulsification cataract extraction.
