Acrysoft ReStOr多焦点人工晶状体的临床应用观察

Clinical application of phacoemulsitication after implantation of an apodized diffractive multffocal I- OL （Acrysoft ReSTOR）

目的 探讨新型Acrysoft ReStOr多焦点人工晶状体的临床应用价值.方法 36例46只眼老年性白内障患者按自愿原则分为两组,多焦组19例（23只眼）单焦组17例（23只眼）均行标准白内障超声乳化吸除术,按分组分别植入ReStOrSA60D3衍射型多焦点人工晶状体和NaturalSN60AT单焦点人工晶状体,观察并记录术后不同时期术眼的裸眼远、近视力、最佳矫正远、近视力、最佳矫正远视力下近视力、拟调节力、对比敏感度及视觉质量等结果.结果 各期两组患者间裸眼远视力、最佳矫正远视力及最佳矫正近视力均差异无统计学意义（P≥0.05）;多焦组裸眼近视力、最佳矫正远视力下近视力和拟调节力显著优于单焦组（P＜0.05）,多焦组近、中距离的视觉质量满意度也较单焦组有明显提高（P＜0.05）.结论 Acrysoft ReStOr多焦点人工晶状体可为白内障术后患者提供良好的远,中,近视力,提高生活质量值得临床推广应用.

Objective To evaluate the clinical effect of a multifocal IOL （Acrysoft ReSTOR）. Methods Thirty-six patients with age-related cataract （46 eyes） were divided into two groups： MIOL group included 19 patients （23 eyes）, SIOL group included 17 patients （23 eyes）. All patients underwent phacoemulsification. MIOL group implanted ReSTOR SA60D3 and SIOL group implanted NaturalSN60AT. At 1 week, 3 months postoperatively, distant and near visual acuities, pseudoaccomodation, contrast sensitivity and patients＇s satisfaction with their vision were assessed. Results Uncorrected distance visual acuity （UCDVA）, Best-corrected distance visual acuity （BCDVA）, Best-corrected near visual （BCNV） in the multifocal were not statistically different from the sonofocal group （P ≥0.05）, Uncorrected near visual acuity （UCNVA）, Best corrected near visual acuity （BCNVA）, pseudoaccomodation and the satisfaction of intermediate and near vision were better statistically in the multifocal group compared to the monofocal group （P 〈0.05）. Conclusions Acrysoft ReSTOR can provide excellent outcomes in distance, intermediate and near vision, so as to improve the quality of life after surgery.
