摘要
目的:研究爆破和阻塞模式在硬核白内障超声乳化术中的联合应用。方法:对核硬度为 3～5级的老年性白内障(48例48只),采用爆破和阻塞模式的联合应用进行超声乳化手术。结果:术后第一天裸眼视力达到 0.3～0.8者25只眼(52.08%),0.9以上者4只眼(8.34%),术后第一周裸眼视力达到0.3～0.8者30只眼(62.25%),0.9以上11只眼(22.92%)。平均有效时间Ⅲ级核为:(15±2.50)s,Ⅳ级核为:(35±5.33)s,Ⅴ级核为:(57±9.12)s。结论:该方法对于硬核白内障手术的安全性高,可明显减少能量的应用,对眼组织的影响也很少,且非常有效。眼科学报2003;19:101-103。
Purpose: To investigate the effect of combined burst and occlude mode in the treatment of hard nucleus cataract during phacoemulisification.
Methods:. Phacoemulisification with combined burst and occlude mode were performed in forty-eight eyes with senile cataracts with nucleus density at grade Ⅲ-Ⅴ. Results: First day after operation, the uncorrected visual acuity in 25 eyes were from 0.3 to 0.8 (52.08%),and 4 eyes is better than 0.9 ( 8.34%). One week later, the visual acuity in 30 eyes has reached to 0.3-0.8 ( 62.25%),and 11 eyes were better than 0.9 (22.92%).The average effective time was (15±2.50) seconds for grade Ⅲ nucleus, (35±5.33) seconds for grade Ⅳ nucleus, and (57±9.12) seconds for grade Ⅴ nucleus. Conclusions: Phacoemulsification with burst and occlude mode was very effective in the treatment of hard nucleus cataract, and was safer. It can decrease phaco power and has little side effect on the ocular tissues. Eye Science 2003 ;19:101-103.
