单眼先天性白内障一期人工晶状体植入观察

Observation of primary intraocular lens implantation on monocular congenital cataract

目的探讨〈2岁的单眼先天性白内障患儿人工晶状体I期植入的有效性及安全性。方法回顾分析2003年7月至2011年3月在延安市人民医院眼科收治的〈2岁的单眼先天性白内障患儿32例（32只眼），均行白内障吸除＋后囊环形撕囊＋前部玻璃体切除＋人工晶状体I期植入术。术后密切随访，详细记录术后并发症的发生情况、屈光状态及矫正视力，眼轴长度。术后随访时间3～10年。结果术后最佳矫正视力为（0．41±0．21），其中≥O．5者16只眼（占50％）；〈0．5～≥0．3者8只眼（占25％）；〈0.3-≥0．1者8只眼（占25％）。统计32例患儿术后3岁时术眼眼轴长度和对侧键眼相近，差异无统计学意义（P〉0．05）。结论〈2岁的单眼先天性白内障I期植入人工晶状体能降低屈光参差性弱视的发生，并促进眼轴的正常发育。

Objective To investigate the effectiveness and safety of primary intraocular lens im- plantation in monocular congenital cataract patients that below 2 years old. Methods Thirty-two patients were collected in Yan＇ an people＇s hospital from July 2003 to March 2011. All the monocular congenital cataract patients were below two years old. The patients were underwent cataract extraction, posterir capsulorhexis, anterjor vitrectomy-and combined with-intraocular lens implantatiQn surgery. i2omplications, refraction, corrected vision, axial length, F-VEP and stereopsis were collected after surgery. All patients were followed up within.3-10 years. Results The best corrected visual acuity of all these cases were 0.41±0.21, 16 eyes were over 0.5 （50%）; 8 eyes were 0.3 to 0.5 （25%）; 8 eyes were 0.1 to 0.3 （25%）. The axial length of the 0perated eye was similar with the opposite eye, so the difference was no statistically significant （P 〉0.05）. Conclusions Primary intraocular lens implantation for monocular congenital cataract below. 2 yearrs old can decrease the rate of anisometropic amblyopia and does not affect the normal development of eyeball.
