摘要
目的比较双眼植入ReSTOR+3D非球面多焦点人工晶状体(MIOL)与ReSTOR+4D球面MIOL后的术后视功能。方法收集18例(36眼)植入ReSTOR+3DMIOL(SN6AD1),15例(30眼)植入ReSTOR+4DMIOL(SA6OD3)的病例。术后第2眼为标准,随访1年。检测两组患者的远、中、近视力及近立体视锐度,并进行相应统计学分析。结果术后裸眼及最佳远视力、近矫正视力两组差异无统计学意义(P>0.05),植入SN6AD1组患者的中距离视力(60cm)好于植入SA6OD3组患者(P<0.05)。焦深曲线提示,SN6AD1组患者40～70cm的中距离视力优于SA6OD3组,而SA6OD3的28cm近视力优于SN6AD1组,两组裸眼近立体视锐度及矫正近视力后的立体视觉,差异均无统计学意义(P>0.05)。结论两种不同近附加度数的ReSTORMIOL植入术后,均可获得良好的远、近视力及近立体视锐度;低度数附加的ReSTORMIOL具有更为理想的全程视力,尤其在中距离视力上表现良好。
Objective To compare the visual performance after binocular implantation of either the ReSTOR muhifocal intraocular lens （MIOL） with a ＋ 3 D （ SN6AD1 ） or the ReSTOR MIOL with a ＋ 4 D （ SA6OD3 ） . Methods This was a prospective study. There were 18 patients （36 eyes） in SN6AD1 group and 15 patients （30 eyes） in SA6OD3 group. The following parameters were assessed 1 year after the surgery： distant, intermediate, near visual aeui- ties （VA） , and near stereoscopic VA. Results The uncorrected, best corrected and/or distance-corrected distant and near VA did not show significant difference between the two groups （ P 〉 0.05 ）. The mean distance-corrected intermedi- ate VA at 60 cm was better in the SN6AD1 group than that in the SA6OD3 group （ P 〈 0.05）. SN6AD1 had better inter- mediate VA at 40 -70 em distance than that of SA6OD3, while SA6OD3 had better VA at 28 em distance than that of SN6AD1 based on the curve of depth. There was no significant difference between the stereoscopic vision for the muhifo- cal and monofocal groups （P 〉 0. 05 ）. Conclusions Both types of hybrid MIOLs could provide fine VA from far to near distance and stereoscopic vision with a low add power. They performed especially well in intermediate visual acuity.
