白内障超声乳化人工晶状体植入术后低视力原因分析

目的分析白内障经超声乳化人工晶状体植入术后低视力的主要原因。方法收集205例(205眼)经超声乳化人工晶状体植入术的白内障患者的临床资料,回顾术后低视力及主要并发症的发生情况。结果本组术后1、7、30 d低视力发生率分别为55.12%、31.70%、11.21%;术后1 d和7 d低视力发生率较高,与超声乳化术后角膜水肿、前房炎症反应、高眼压的发生及程度有关;术后1月低视力发生率与文献报道(13.21%)接近。结论手术并发症是导致超声乳化人工晶状体植入术后低视力的主要原因。熟练掌握超声乳化技巧,有助于提高术后视力。

Analysis of causes for postoperative low vision after cataract phacoemulsification and intraocular lens implantation

Objective To analyze the main causes of postoperative low vision after cataract phacoemulsification and intraocular lens implantation. Methods The clinical data of 205 cases(205 eyes) with cataract phacoemulsification and intraocular lens implantation were collected.The incidences of postoperative low vision and main postoperative complications were retrospectively analyzed. Results The incidences of postoperative low vision were 55.12%,31.70% and 11.21%,respectively for the first,7th and 30th day after operation.The relatively high incidences of the first day and 7th day after operation were related to the occurrence and degree of cornea edema,anterior chamber imflammation and high intraocular pressure.The incidence of postoperative low vision of the first month after operation was similar to that reported in the previous literature(13.21%). Conclusion Postoperative complications are the main causes leading to postoperative low vision after cataract phacoemulsification and intraocular lens implantation.Proficient phacoemulsification operation skills may contribute to the improvement of eyesight after operation.
