摘　　要：目的:探讨白内障超声乳化术中后囊破裂时残留晶体核的处理方法。方法:回顾性地研究18例(18眼)超声乳化术中后囊穿破时残留晶体核的处理结果。介绍低流量、低灌注、连续超声乳化法;注入高弹性粘弹性剂法;无灌注前段玻璃体切除(“干切”)等三种防止晶体核下沉的方法。随访12～24个月,平均18.2个月。结果:除1例特殊患者外,均未发生核下沉,且均一期植入后房型人工晶体。随访时视力达到0.5者有15眼(83.3％)。手术并发症主要是角膜水肿、黄斑囊样水肿等。结论:3种处理方法适应于不同类型的残留核的处理,且安全,可靠,并发症少,值得临床推广。眼科学报2000;16:106-108。Objective: To investigate some surgical techniques in dealing with a impending dropped nucleus when posterior capsular rupture during the phacoemulsification. Methods: The postoperative results of 18 cases (18 eyes) whose posterior capsular of lens ruptured with a impending dropped nucleus during the phacoemulsification were studied retrospectively. Three surgical techniques to prevent lens nucleus' fragments dropping into the vitreous cavity were applied. They are consecutive phacoemulsification with lower flowing rate and lower irrigation, injection of viscoelastic substance with high elasticity and anterior segment vitrectomy with no irrigation. The follow-up was 12-24 months (average, 18. 2 months). Results: Except for a special case, no lens nucleus' fragments dropped into the vitreous cavity. Posterior chamber intraocular lens(IOL) was implanted primarily in all cases (18 eyes) . Best corrected visual acuity was above 0. 5 in 15 eyes (83. 3% ) . The main complications included corneal edema and cystoid macular edema. Conclusion: With safety, effectiveness and less complications, these three surgical techniques are suitable to deal with different types of impending dropped lens nucleus' fragments during the phacoemulsification. It is advisable to apply these techniques in clinical practice. Eye Science 2000; 16: 106 - 108.
