目的 探讨白内障手术切口大小与疗效的关系。方法 选择双眼白内障患者30例共60眼,一眼行常规大切口手术作好对照组,另一眼行小切口手术进行对比研究。结果 随访3个月,视力≥1.0者小切口组为83％,对照组为33％,二者相差显著(P<0.05),此外,小切口经术中并发症少,术后散光小。结论 小切口术式简单易行,损伤轻,恢复快,术后视力满意。 Objective To investigate the relationship between the surgical incision size and curative effect of cataract surgery. Methods A total of 60 eyes of 30 patients with binocular cataract were selected. One was performed conventional large incision operation and the other was operated by small incision. Results The follow-up of 3 months showed that the visual acuity ≥1.0 was 83% in the small incision group and 33% in the control group, the difference was significant (P <0.05). In addition, the small incision had less intraoperative complications and less postoperative astigmatism. Conclusion Small incision is simple and easy to operate with less damage, faster recovery and satisfactory postoperative visual acuity.
