摘要
目的 :对单焦点和多焦点人工晶状体植入术后的拟调节力进行比较。方法 :选取合适的老年性白内障患者 ,分为两组。Ⅰ组 :30例 32只眼 ,植入AllerganArraySA 4 0NBTM多焦点人工晶状体 ,平均随访时间为 9.4个月。Ⅱ组 :30例 32只眼 ,植入AllerganSI4 0单焦点人工晶状体 ,平均随访时间为 15 .7月。所有病例均由同一眼科医师行标准超声乳化白内障摘除术联合人工晶状体植入术。术后采用试镜片法测试拟调节力。结果 :Ⅰ组 (MIOL)视远拟调节力为(2 .79± 0 .86 )D ,视近拟调节力为 (3.6 4± 1.0 3)D ;Ⅱ组(SIOL)视远拟调节力为 (0 .75± 0 .38)D ,视近拟调节力为 (1.0 6± 0 .4 2 )D ,两组差异有非常显著性 (P <0 .0 1)。结论 :多焦点人工晶状体可以使患者在术后获得较大范围的拟调节力 ,使人工晶状体的作用更接近于生理性晶状体。
Objective:To investigate pseudoaccommodation between the multiple focus intraocular lens(MIOL) implantation and single focus intraocular lens(SIOL) implantation.Methods:Sixty elderly cataract patients were enrolled and divided into two groups. Group Ⅰ:30 cases(32 eyes) were implanted with Allergan Array SA-40NB TM MIOL. The average follow-up visit was 9.4 months. Group Ⅱ:30 cases(32 eyes) were implanted with Allergan SI40 single focus intraocular lens(SIOL). The average follow-up visit was 15.7 months. All surgical procedure underwent standard phacoemulsification by the same ophthalmologist. Distance and near pseudoaccommodation were measured by the method of negative lenses.Results:Group Ⅰ(MIOL):distant pseudoaccommodation was an average of (2.79±0.86)D,and near was (3.64±1.03)D,P<0.01;group Ⅱ(SIOL):distant pseudoaccommodation was an average of (0.75±0.38)D,and near was (1.06±0.42)D,P<0.01.Conclusion:MIOL can provide a wide range of pseudoaccommodation for the patient.[
