白内障术后影响视力因素分析

Influencing Factors on Visual Acuity of Post Cataract

目的回顾性分析白内障超声乳化联合人工晶体植入术后患者的视力恢复情况及影响因素。方法选取2004年1月至2005年1月接受白内障超声乳化联合人工晶体植入术的白内障患者1000例（1278眼），分析术后3d及1年患者的视力情况及影响因素。结果术后3d裸眼或矫正视力／〉0．3者368例（446眼）；裸眼或矫正视力〈0．3者632例（832眼），影响视力的主要因素是角膜水肿。术后1年裸眼或矫正视力≥0．3者635例（820眼），裸眼或矫正视力〈0．3者365例（458眼），影响视力的主要因素是后囊膜混浊。结论白内障超声乳化联合人工晶体植入术后患者的视力恢复情况较好。

Objective To analyse the recovery of visual acuity and the factor that influence it retrospectively after phacoemulsifieation cataract combined with intraoeular lens implantation. Methods Analyze the visual acurity and the influencing factors of 1000 cases（ 1278 eyes） which adopted phacoemulsification cataract combined with intraoeular lens implantation after 3 days and 1 year from January 2004 to January 2005. Results 3 days after operation, 368 cases （446 eyes）with naked eyesight or corrected vision ≥0.3 and 632 cases（832 eyes） with naked eyesight or corrected vision 〈 0.3 ,corneal edema may have influenced the visual acuity as the main factor. 635 cases（820 eyes）with naked eyesight or corrected vision ≥0.3 and 365 cases（458 eyes）with naked eyesight or corrected vision 〈 0.3, posterior capsular opacification may have influenced the visual acuity as the main factor. Conclusion The recovery of visual acuity is better after cataract phacoemulsification combined with intraocular lens implantation.
