目的比较三种多焦点人工晶状体(IOL)ReSTOR+4.0D、IQReSTOR+4.0D和IQReSTOR+3.0D的临床效果,评估植入IQReSTOR+3.0D后的视觉功能。设计前瞻性病例系列研究。研究对象老年性白内障患者47例(72眼)。方法对以上患者行白内障超声乳化吸除和IOL植入术,按患者自愿原则,分别植入ReSTOR+4.0D18例(27眼),IQReSTOR+4.0D15例(25眼),IQReSTOR+3.0D14例(20眼)。比较患者术后3个月的近距离、中距离和远距离视力、对比敏感度、波前像差和离焦曲线。主要指标近距离、中距离和远距离裸眼和矫正视力,对比敏感度,波前像差,离焦曲线和问卷调查。结果术后3个月,IQReSTOR+3.0D组裸眼中距离LogMAR视力(0.169±0.07)较ReSTOR+4.0D组(0.256±0.08)和IQReSTOR+4.0D组(0.252±0.08)好,差异有统计学意义(P=0.000,P=0.001)。近距离和远距离视力,三组没有统计学差异(P均>0.05)。离焦曲线显示IQReSTOR+3.0D组的近距离视力在-2.0D～-2.5D,相当于眼前40～50cm范围有一高的平台,而ReSTOR+4.0D组和IQReSTOR+4.0D组仅为一个点。三组患者术后3个月的夜间视力模糊、眩光和光晕没有统计学差异。结论衍射多焦人工晶状体+3.0D较+4.0D能够提供更好的中距离视力和一定距离范围近视力。
Objective To compare the clinical effects of three multifocal intraocular lenses (IOLs) ReSTOR + 4.0D, IQReSTOR + 4.0D and IQReSTOR + 3.0D to evaluate the visual function after implantation of IQRestor + 3.0D. Design prospective case series. The study included 47 patients (72 eyes) with senile cataract. Methods The above patients underwent phacoemulsification and IOL implantation. ReSTOR + 4.0D18 patients (27 eyes), IQReSTOR + 4.0D15 eyes (25 eyes), IQRestor + 3.0D14 patients 20 eyes). The short, mid-range and long-distance visual acuity, contrast sensitivity, wavefront aberration and defocus curve were compared between 3 months postoperatively. MAIN INDICATORS Short-range, medium-range and long-distance naked eyes and corrected visual acuity, contrast sensitivity, wavefront aberration, defocus curve and questionnaire. Results At 3 months after operation, the LogMAR visual acuity (0.169 ± 0.07) in the naked eye of IQReSTOR + 3.0D group was better than that of ReSTOR + 4.0D group (0.256 ± 0.08) and IQRestor + 4.0D group (0.252 ± 0.08) Significance (P = 0.000, P = 0.001). Short-distance and long-distance vision, the three groups had no statistical difference (P all> 0.05). The defocus curve showed that the short-term visual acuity was between -2.0D and -2.5D in the IQRestor + 3.0D group, which was equivalent to a high platform in the range of 40-50cm before the eye, whereas the ReSTOR + 4.0D group and the IQRestor + 4.0D group were only one point . There was no statistical difference in glare and halo between the three groups at 3 months postoperative night vision blur. Conclusions Diffractive multifocal intraocular lens + 3.0D vs + 4.0D can provide better mid-range visual acuity and near-range visual acuity.
