探讨一种更为有效的非超声乳化小切口白内障术式。方法 :在 6mm隧道切口下 ,采用医用涤纶线套切晶状体核的方法 ,行老年性白内障囊外摘除并后房型人工晶体植入术 31 1例、343只眼。结果 :术后 1天、1个月、3个月视力检查 :≥ 0 .5者分别占 85.1 %、89.2 %和 95.8% ;视力≥ 1 .0者分别占 2 8%、64%和 67%。术后 3天、1个月、3个月进行散光检查 ,平均分别为 1 .2 1± 0 .87D、1 .0 0± 0 .79D和 0 .93± 0 .82 D,与同期所行的 6mm切口超声乳化白内障摘除后房型人工晶体植入术比较 ,差异无显著性 (P>0 .0 5)。结论 :线切核白内障摘除术除具有切口小、创伤少、视力恢复快等优点外 ,对眼角膜内皮组织损伤小 ,并能摘除各种硬核白内障 ,使小切口非超声乳化白内障摘除手术更加安全、有效。
To explore a more effective non-phacoemulsification small incision cataract surgery. Methods: Under the incision of 6mm tunnel, 31 cases of cataract extraction with posterior chamber intraocular lens implantation and 343 eyes of posterior chamber intraocular lens implantation were performed with medical polyester sheath core method. Results: 1 day, 1 month and 3 months postoperative visual acuity examination: ≥0.5 accounted for 85.1%, 89.2% and 95.8% respectively; visual acuity≥1.0 accounted for 28%, 64% and 67% . After 3 days, 1 month, 3 months astigmatism examination, an average of respectively 1.21 ± 0.87D, 1. 0 ± 0.79D and 0.93 ± 0.82D, with the same period The 6mm incision phacoemulsification cataract extraction posterior chamber intraocular lens implantation, the difference was not significant (P> 0.05). Conclusions: In addition to the advantages of small incision, less trauma and faster visual acuity, mitotic cataract extraction has less damage to the corneal endothelium and can remove all kinds of hard nucleus cataracts, so the operation of small incision non-phacoemulsification cataract surgery is more Safe and effective.
