折射型多焦点人工晶状体植入术后视觉质量评价

目的评价折射型多焦点人工晶状体(multifocal intraocular lens,MIOL)植入术后的视觉质量。方法采用前瞻性非随机对照研究。对114例老年性白内障患者行超声乳化白内障吸除联合人工晶状体植入术,分为折射型多焦点人工晶状体植入组(ReZoom组)和非球面单焦点人工晶状体植入组(Tecnis ZA9003组)各57例(57眼)。术后3个月时检查裸眼及矫正远、近视力、最佳矫正远视力下的近视力、波前像差、调制传递函数值、40、63、100 cm对比度视力和拟调节力,并比较视近脱镜率。结果术后3个月,裸眼近视力和最佳矫正远视力下的近视力ReZoom组明显优于Tecnis ZA9003组(P<0.05),调节幅度ReZoom组大于TecnisZA9003组(P<0.05)。瞳孔直径3 mm和5 mm时,ReZoom组总高阶像差大于Tecnis ZA9003组,差异具有统计学意义;瞳孔直径3 mm时,ReZoom组彗差大于Tecnis ZA9003组,差异有统计学意义。在40、63、100 cm对比度视力得分(VAS分值)ReZoom组均高于TecnisZA9003组(P<0.05)。5、10、15、20 cpd调制传递函数值ReZoom组小于Tecnis ZA9003组(P<0.05)。ReZoom组近用脱镜率为96.49%,优于Tecnis ZA9003组(29.82%),差异有统计学意义。结论与非球面单焦点人工晶状体比较,虽然折射型多焦点人工晶状体高阶像差稍高,但具有一定的拟调节力,可获得良好远、中、近视力,适合于迫切要求脱镜的患者。

Quality of Vision in Patients with Refractive Multifocal Intraocular Lens Implantation

Objective To observe the visual performance of patients with ReZoom refractive multifocal intraocular lens(IOL) compared with aspheric monofocal IOL.Methods This was a prospective nonrandomized controlled study.Totally 114 consecutive senile cataract patients(114 eyes) were enrolled into this study.Fifty-seven cataract patients(57 eyes) were implanted with ReZoom refractive multifocal IOL(ReZoom group),and another 57 cataract patients(57 eyes) were implanted with aspheric monofocal IOL(Tecnis ZA9003 group)....
