探讨经颞侧透明角膜隧道切口的二期人工晶体植入术的方法及优点。方法 :用钻石刀在颞侧角膜周边血管弓中央的透明角膜上 ,做一深 0 3mm ,长 3 2mm ,宽 1 75mm的角膜隧道切口 ,对 5 0例5 3只眼的无晶体眼行二期人工晶体植入术 ,植入可折叠人工晶体。随访 6～ 12个月 ,平均 8 4个月 ,观察术后视力、角膜曲率、人工晶体位置及术中、术后并发症。结果 :手术时间为 15～ 40分钟 ,平均 2 6分钟。术后第一天矫正视力≥ 0 5者 2 0只眼 (占 37 73 % ) ;术后 1周和 3个月矫正视力≥ 1 0者分别为 2 6眼 (占 49 0 5 % )和 35眼 (占 6 6 0 3 % )。术后一天和三个月平均散光为 0 6 1± 0 42D和 0 5 1± 0 37D与术前比较无统计学差异。手术并发症主要为术中后囊破裂 ( 5眼 ) ,术后晶体偏心 ( 2眼 )和黄斑囊样水肿 ( 3眼 )。结论 :经颞侧透明角膜隧道切口的二期折叠式人工晶体植入术具有手术时间短、并发症少、操作简单、视力恢复快等优点 ,适应于绝大部分的无晶体眼患者。
To explore the methods and advantages of the second-stage intraocular lens implantation through temporal clear corneal tunnel incision. Methods: A deep corneal tunnel incision with depth of 3 mm, length of 32 mm and width of 1 75 mm was made on a clear cornea of the blood vessel arch around the temporal cornea with a diamond knife. Fifty eyes of 50 eyes Phacoemulsification and implantation of foldable intraocular lens. The patients were followed up for 6 to 12 months, with an average of 84 months. The postoperative visual acuity, corneal curvature, intraocular lens position and intraoperative and postoperative complications were observed. Results: The operation time was 15-40 minutes with an average of 26 minutes. The corrected visual acuity ≥ 0 5 and 20 eyes (37 73%) on the first postoperative day were 26 eyes (49 0 5%) and 35 eyes corrected visual acuity ≥ 1 0 at 1 week and 3 months respectively Eye (6 6 0 3%). The mean astigmatism of one day and three months after surgery was 0 6 1 ± 0 42D and 0 5 1 ± 0 37D with no significant difference compared with that before operation. The main complications were intraoperative posterior capsule rupture (5 eyes), postoperative lens eccentricity (2 eyes) and cystoid macular edema (3 eyes). CONCLUSION: The IIFI tunnel incision with double temporal foldable intraocular lens implantation has the advantages of shorter operation time, fewer complications, simple operation and quick recovery of visual acuity, which is suitable for the majority of patients with aphakia.
