手法碎核在白内障超声乳化摘除术中的应用

Application of manual chopping nucleus technique in phacoemulsification cataract surgery

摘要:

目的：观察手法碎核技术在白内障超声乳化摘除术中的应用效果。方法：选取2011-05/10老年性白内障132例179眼,其中男56例82眼,女76例97眼；年龄53～74（平均67.7±6.4）岁。排除伴有晶状体脱位、青光眼及葡萄膜炎等。手法碎核后再行超声乳化术,观察手术中超声能量和作用时间、术后视力和角膜水肿等,随访时间1wk。结果：手法碎核后超声乳化白内障摘除术中所需超声能量低,术后角膜水肿等术后并发症的发生率较低。结论：手法碎核技术在白内障超声乳化摘除术中的应用是安全有效的。

Abstract:

AIM： To observe the effect of manual chopping nucleus technique in phacoemulsification cataract surgery.METHODS: The manual chopping nucleus technique was performed in 132 cases (179 eyes) of age-related cataract with hard nucleus gradedⅢ,Ⅳ and Ⅴ before phacoemulsification. Male were 56 cases (82 eyes), female were 76 cases (97 eyes), the age was 53-74 (average 67.7±6.4) years. Subjects with lens dislocation, glaucoma and uveitis were exclused. Intraoperative phaco power and time, postoperative visual acuity and corneal edema were observed, and the follow-up were carried out for 1 week. RESULTS: Manual chopping nucleus technique before phacoemulsification reduced the release of ultrasound power. The low incidence of corneal edema was found postoperatively. CONCLUSION:Manual chopping nucleus technique was safe and effective in phacoemulsification cataract surgery.
