AcrySof ReSTOR多焦点人工晶状体植入术后的视功能观察

Observation of visual function in eyes implanted with AcrySof ReSTOR multifocal intraocular lens

目的 探讨年龄相关性白内障患者行超声乳化联合AcrySof ReSTOR多焦点人工晶状体（MIOL）植入术后的视功能及视物满意度.方法 回顾性研究.将20例（40眼）植入AcrySof ReSTOR＋3D MIOL患者（观察组）与20例（40眼）植入AcrySof IQ单焦点人工晶状体患者（对照组）进行对比,观察两组患者术后3个月相同光照条件下远、中、近裸眼及最佳矫正视力和立体视锐度;并对术后视物满意度进行问卷调查.所得数据资料的比较采用秩和检验.结果 观察组的裸眼中距视力、远矫正下的中距视力、裸眼近视力、远矫正下的近视力均显著高于对照组（Z=2.978,P＜0.01;Z=3.040,P＜0.01;Z=3.471,P＜0.01;Z=3.098,P＜0.01）.观察组立体视锐度显著高于对照组（Z=2.264,P＜0.05）.观察组中,中距离、近距离视物满意度（96%、100%）明显好于对照组（77%、50%）.结论 双眼植入AcrySof ReSTOR＋3DMIOL患者拥有良好的全程视力以及近立体视锐度,生活质量得到了提高.

Objective To discuss the visual function and subjective parameters in patients who underwent implantation of ReSTOR apodized diffractive multifocal intraocular lens on both eyes.Methods This was a retrospective study. Forty eyes of 20 patients received implantation of ReSTOR multifocal intraocular lens （observe group） and 40 eyes of 20 patients received implantation of IQ monofocal intraocular lens （control group） participated in the study. All patients were assessed at 3 months postoperatively under the same luminance conditions, far, intermediate and near uncorrected and corrected visual acuity, near stereoacuity were observed, a questionnaire survey was conducted.Data was examined by rank sum test. Results At 3 months postoperation, uncorrected intermediate visual acuity, intermediate visual acuity after distant correction, uncorrected near visual acuity and near visual acuity after distant correction in observe group were significantly higher than those of control group （Z=2.978, P〈0.01; Z=3.040, P〈0.01; Z=3.471, P〈0.01; Z=3.098, P〈0.01）.The stereoacuity of the observe group was much better than that of the control group, which had significant meaning （Z=2.264, P〈0.05） and patients in the observe group had higher satisfaction in near and intermediate visual acuity. Conclusion Binocular implantation of multifocal intraocular lens could provide patients with good vision, as well as good stereoacuity.
