植入不同附加度数ReSTOR多焦点人工晶状体术后视觉质量的比较

目的比较研究植入2种不同附加度数ReSTOR多焦点人工晶状体术后的视觉质量。方法回顾性分析在我科行白内障超声乳化吸出并植入ReSTOR多焦点人工晶状体的病例共62例(92眼),按植入晶状体类别分组,植入SN6AD1MIOL为+3.0D组,植入SN60D3MIOL为+4.0D组。检查2组病例术后3个月的裸眼及矫正的远(5m)、中(70cm、60cm、50cm)、近(40cm、33cm)距离视力;测量双焦曲线,并收集白内障术后患者问卷调查。结果术后3个月,2组远距离视力以及最佳矫正近视力比较,差异均无统计学意义(均为P>0.05),+3.0D组在中距离视力上好于+4.0D组(P<0.05),而33cm裸眼近视力+4.0D组好于+3.0D组,40cm裸眼近视力+3.0D组好于+4.0D组(P<0.05)。2组的双焦曲线(-5.0～5.0D)相似,均形成双峰,+3.0D组远视力峰值在0D、-2.5D,+4.0D组峰值在0D、-3.5D。+4.0D组问卷调查有2例患者抱怨在进行中距离视物时遇到困难(1例不能看清1m远电脑屏幕,另1例看不清60cm远手机屏幕),+3.0D组在各个距离日常视觉活动中未遇困难。2组均无严重的视觉干扰现象。结论本研究中的2种多焦点人工晶状体都能提供良好的全程视力,显著提高患者的生活质量。植入SN6AD1MIOL在中距离视力和40cm裸眼近视力表现较好,而植入SN60D3MIOL则在33cm裸眼近视力上表现较好。

Visual outcomes after implantation of ReSTOR multifocal intraocular lens with different addition powers

Objective To evaluate visual quality after implantation of ReSTOR multifocal intraocular lens with two kinds of addition powers. Methods Retrospective study was taken in 62 cases(92 eyes) underwent phacoemulsification and implantation of ReSTOR multifocal intraocular lens.According to types of intraocular lens,all patients were divided into two groups.The patients,who were implanted with SN6AD1 MIOL,was +3.0 D group,and who were implanted with SN60D3 MIOL,was+4.0 D group.Naked and corrected distance(5 m),in...
