摘　　要：目的 探讨爆破式超声乳化联合拦截劈核术在硬核自内障摘除术中的应用。方法 采用爆破式超声乳化联合拦截劈核术施行白内障手术65例（65只眼），其中Ⅲ级核12只眼，Ⅳ级核34只眼，Ⅴ级核19只眼。结果 术后第1天视力0．3～0．5者6只眼（9．2％），0．6～0．8者46只眼（70．8％），〉0．8者10只眼（15．4％）；术后3个月视力0．3～0．5者4只眼（6．2％），0．6～0．8者37只眼（56．9％），〉0．8者21只眼（32．3％）；术后1、3个月平均角膜散光与术前相比较，差异无显著性（P〉0．05）。角膜水肿8只眼，后囊膜破裂2只眼，少量晶状体碎核沉入玻璃体1只眼。结论 爆破式超声乳化联合拦截劈核术，可使分割较硬的晶状体核变得更容易，减少了能量的使用，缩短了超乳时间。该方法安全、有效，适合于硬核白内障手术。Objective To investigate the use of bursting phacoemulsification and stop-and-chop in hard nuclear cataracts . Methods 65 cases （65 eyes） were received bursting phacoemulsification and stop-and-chop , hardness of nucleus were grade Ⅲ in 12eyes , grade Ⅳ in 34 eyes , grade Ⅴ in 19 eyes. Results One day after operative , the visual acuity was 0.3～0.5 in 6 eyes （9.2%） ,0.6～0.8 in 46 eyes（70.8% ）, 〉 0.8 in 10 eyes（ 15.4% ） ;three months after operative , the visual acuity was 0.3 ～ 0.5 in 4 eyes （6.2 % ） ,0.6～0.8 in 37 eyes（ 56.9% ） , 〉 0.8 in 21 eyes （32.3%） ;there was no significant difference between the mean preoperative astigmatism and astigmatism in postoperative 1 month and 3months （ P 〉 0.05 ） . moderate corneal edema take place in 8 eyes , posterior capsule rupture appear in 2 eyes , little lens fragments dropped into the vitreous 1 eye . Conclusion The hard nucleus is easy to be divided by the bursting phacoemulsification and stop-and-chop , so the power and time of phacoemulsification is decreased . the method can be used safely and effectively for hard nucleus cataracts .
