【摘要】 目的:探讨隧道小切口晶状体核分瓣技术对提高视力及减少白内障术后并发症的意义。方法:随机抽样,分别对行小切口晶状体核分瓣法的120只眼及行传统白内障体外摘除术(ECCE)的80只眼进行回顾性分析,比较两组术后1周和1个月的视力、角膜散光及术中和术后并发症。结果:小切口组术后1周有112眼(93.3%)最好矫正视力高于0.5,ECCE组术后1周有48眼(60%)视力高于0.5,差异具有显著性(x~2=4.73,P<0.05)。小切口组的术后角膜散光分别为(1.01±0.97)D(n=95;术后1周)和(0.62±0.53)D(n=90;术后1个月),ECCE组术后角膜散光为(4.46±1.93)D(n=70;术后1周)及(2.74±1.54)D(n=60),差异有显著性(t=3.1467,P<0.01和t=3.4753,P<0.01)。结论:隧道小切口晶状体核分瓣技术安全、省时、术后恢复快、费用低,值得在一定范围内推广。眼科学报 2002;18:223-225.更多还原

【Abstract】 Purpose: To explore the advantages of nuclear manual-chop technique in small incision cataract surgery.Methods: By randomly sampled, post-operative visual acuity, corneal astigmatism and complications (one month of follow-up) of 120 eyes of small incision sutureless surgery associated with nuclear manual-chop were compared to that of 80 eyes of traditional ECCE with IOL implantation.Results: Visual acuity of 112 eyes(93. 3% ) of small incision group in one week postoperatively was increased 0. 5 above compared to that of 48 eyes (60% ) of ECCE group. The difference was statistically significant (x2=4. 73, P < 0. 05) . In small incision group, the corneal astigmatism was (1. 01 ±0. 97 ) D ( n = 95 ) in one week postoperatively and (0. 62 ± 0. 53)D( n - 90) in one month postoperatively. A significant difference existed between the small incision group and ECCE group (t =3. 1467, P < 0. 01 and t - 3. 4753, P < 0. 01). As for post-operative complications, in small incision group, one post-capsule rupture was recorded.Conclusion: Small incision sutureless surgery with manual-chop technique is worth developing and spreading because of its advantages.
