目的 :探讨隧道自闭式小切口不缝线非超声乳化人工晶体植入术的临床疗效。方法 :对 30例老年性白内障 34眼行巩膜隧道反眉形自闭式 6mm小切口手术 ,并与传统的 10～ 13mm大切口病例术后视力及角膜散光情况进行对比。结果 :小切口组 34眼术后 5d及 2个月裸眼视力≥ 0 .5者分别为 75 %与 92 % ,大切口组 12眼分别为 5 5 %与 75 %。差异有高度显著性 (P <0 .0 1) ,角膜散光度小切口组术后 5d及 2个月为 1.73± 0 .32D ,与常规大切口组 2 .92± 0 .97D相比差异有高度显著性 (P <0 .0 1) ,结论 :采用巩膜隧道自闭式小切口不缝线非超声乳化人工晶体植入术适应证广 ,不受核硬限制 ,易掌握 ,手术操作简便 ,费用低廉 ,不需昂贵医疗设备 ,对组织损伤轻 ,切口愈合好 ,视力恢复快 ,角膜散光小 ,且稳定 ,并发症少。
Objective: To investigate the clinical efficacy of tunnel self-closing small incision sutureless non-phacoemulsification intraocular lens implantation. Methods: Thirty eyes of 30 cases with senile cataract were treated with scleral tunnel anti - eyebrow 6mm mini - incision and compared with the postoperative visual acuity and corneal astigmatism of 10 ~ 13mm large incision. Results: In the small incision group, the visual acuity of the naked eye ≥ 0.5 at 5 d and 2 months after operation in the small incision group was 75% and 92% respectively, while that in the large incision group was 55% and 75% respectively. The difference was highly significant (P0.01). The small incision corneal astigmatism group was 1.73 ± 0.32D at 5 days and 2 months after operation, which was different from that of the conventional large incision group (2.92 ± 0.97D) (P0.01) .Conclusion: Scleral tunnel incision with small incision suture non-phacoemulsification intraocular lens implantation indications, not hard core limits, easy to grasp, the operation is simple, Low cost, without expensive medical equipment, tissue damage, incision healed well, rapid visual acuity, corneal astigmatism small, and stable, less complications.
