AIMTo 估计小切口 lenticule 抽取(微笑) 的效果在到 1mo postoperatively.METHODSA 的 1d 的角膜的内皮细胞层上的外科回顾的、观察学习在收到了微笑外科的 47 个病人(47 只眼睛) 上被进行。病人们根据接触透镜被组织穿状况。角膜的内皮细胞层手术后地外科手术前地并且在 1d, 1wk 和 1mo 被检验。角膜的内皮细胞层被分析因为 endothelial 房间密度( ECD ),六角形的房间的百分比,和房间 size.RESULTSThere 的变化( CV )的系数不是在 ECD 的重要减少,在在 1d 的 CV 的六角形的房间或增加的百分比, 1wk 和 1mo 手术后地( P> ; 0.05 )。然而,在接触透镜穿戴者有在 2.88% 的 ECD 的小增加(78.26 ±; 113.62 房间 / 公里 2, P<; 0.05 ).CONCLUSIONSMILE 没在 1mo 后续时间期间在角膜的 ECD 和形态学上有重要不利效果。
AIM: To assess the effects of small incision lenticule extraction(SMILE) surgery on the corneal endothelium at1 d to 1mo postoperatively.·METHODS: A retrospective, observational study was conducted on 47 patients(47 eyes) who received SMILE surgery. Patients were grouped according to contact lens wear condition. The corneal endothelium was examined preoperatively and at 1d, 1wk and 1mo postoperatively.The corneal endothelium was analyzed for endothelial cell density(ECD), percentage of hexagonal cells, and coefficient of variation(CV) of cell size.·RESULTS: There were no significant decrease in the ECD, percentage of hexagonal cells or increase in CV at1 d, 1wk and 1mo postoperatively(P 〉0.05). However,there was a small increase of ECD by 2.88% in contact lens wearers(78.26±113.62 cell/mm2, P 〈0.05).· CONCLUSION: SMILE has no significant adverse effects on the corneal ECD and morphology during 1mo follow-up time.
