目的 评价Fuchs角膜内皮营养不良 (FED)患者行白内障摘除人工晶状体植入术的临床效果。方法 对连续的 2 0 2 6例 (2 0 2 6只眼 )老年性白内障患者行白内障摘除人工晶状体植入术 ,其中术前行角膜内皮细胞检查确诊为FED患者 1 7例 (1 7只眼 ) ,记录手术方式、术中保护角膜内皮细胞的方法 ,观察手术前、后角膜内皮细胞的变化 ,以及术后视力和角膜状况。结果 老年性白内障患者中FED的发生率为 0 8% (1 7 2 0 2 6)。白内障摘除人工晶状体植入术后角膜内皮细胞的丢失率为1 6 2 % (32 4 1 998)。 94 1 % (1 6 1 7)患者术后最佳矫正视力≥ 0 5。随访时间 6～ 36个月 ,无角膜内皮功能失代偿者。结论 白内障摘除术前对老年性白内障患者进行角膜内皮细胞检查具有十分重要的临床意义 ;白内障摘除术中对FED患者的角膜采取保护措施和由技术熟练的术者完成手术 ,是手术获得满意疗效的重要保证。
Objective To evaluate the clinical effect of cataract extraction and intraocular lens implantation in patients with Fuchs corneal endothelial dystrophy (FED). Methods Cataract extraction and intraocular lens implantation were performed on 2 0 2 6 consecutive cases (2 0 2 6 eyes) of senile cataract patients, of which 17 cases (17 eyes) were diagnosed by corneal endothelial cell examination before operation ), Recording surgical methods, intraoperative protection of corneal endothelial cells, before and after surgery to observe changes in corneal endothelial cells, as well as postoperative visual acuity and corneal status. Results The incidence of FED in patients with senile cataract was 0.8% (17 2 0 2 6). Corneal endothelial cell loss after cataract extraction and intraocular lens implantation was 162% (32 4 1 998). 94 1% (1 6 1 7) patients with best corrected visual acuity ≥ 0 5. Follow-up time 6 to 36 months, no corneal endothelial dysfunction who. Conclusions Corneal endothelial cell examination in senile cataract patients before cataract extraction is of great clinical significance. In cataract extraction, protective corneas of FED patients and operation by skilled surgeons are completed, which is a satisfactory result for surgery Important guarantee.
