目的:比较同样硬度核两种术式的优缺点。对象与方法:在健康快车上进行1006例手术,其中级核143眼行囊外摘除(ECCE)术,162眼行超声乳化术(Phaco)级核441眼中ECCE319眼,Phaco122眼。结果:级核ECCE手术并发症多于Phaco,P<001视力较Phaco低,级核术中后囊破裂Phaco稍高于ECCE,但无统计学意义P>05。但视力仍优于ECCE,级核Phaco70岁以上术中并发症较70岁以下多,但无统计学意义P>05。结论:级核、级核Phaco术优于ECCE,但70岁以上级核如病史时间长Phaco慎重。
Objective: To compare the advantages and disadvantages of two surgical procedures of the same hardness. PARTICIPANTS AND METHODS: One hundred and sixty-six patients undergoing ECT were enrolled in this study. Among them, ECCE was performed in 143 eyes of middle-grade nucleus, ECCE319 eyes and Phaco122 eyes in 441 eyes of 162 phacoemulsification patients. Results: The complications of grade ECCE were more than those of Phaco, P <001 was lower than that of Phaco, and the degree of posterior capsule rupture was slightly higher than that of ECCE in grade one, but no statistical significance (P> 0.05). However, the visual acuity was still superior to ECCE. The intraoperative complications of grade Phaco over 70 years old were more than those under 70 years old, but no statistical significance (P> 0.05). CONCLUSIONS: Grade and grade Phaco are superior to ECCE, but those over 70 are more likely to be Phaco over time.
