摘要/Abstract

摘要： 目的评价折射型多焦点人工晶状体（multifocal intraocular lens，MIOL）植入术后的视觉质量。方法采用前瞻性非随机对照研究。对114例老年性白内障患者行超声乳化白内障吸除联合人工晶状体植入术，分为折射型多焦点人工晶状体植入组（ReZoom组）和非球面单焦点人工晶状体植入组（Tecnis ZA9003组）各57例（57眼）。术后3个月时检查裸眼及矫正远、近视力、最佳矫正远视力下的近视力、波前像差、调制传递函数值、40、63、100 cm对比度视力和拟调节力，并比较视近脱镜率。结果术后3个月，裸眼近视力和最佳矫正远视力下的近视力ReZoom组明显优于Tecnis ZA9003组(P＜0.05)，调节幅度ReZoom组大于TecnisZA9003组（P＜0.05）。瞳孔直径3 mm和5 mm时，ReZoom组总高阶像差大于Tecnis ZA9003组，差异具有统计学意义；瞳孔直径3 mm时， ReZoom组彗差大于Tecnis ZA9003组，差异有统计学意义。在40、63、100 cm对比度视力得分（VAS分值）ReZoom组均高于TecnisZA9003组（P＜0.05)。5、10、15、20 cpd调制传递函数值ReZoom组小于Tecnis ZA9003组（P＜0.05)。ReZoom组近用脱镜率为96.49%，优于Tecnis ZA9003组（29.82%），差异有统计学意义。结论与非球面单焦点人工晶状体比较，虽然折射型多焦点人工晶状体高阶像差稍高，但具有一定的拟调节力，可获得良好远、中、近视力，适合于迫切要求脱镜的患者。

Abstract: Objective To observe the visual performance of patients with ReZoom refractive multifocal intraocular lens(IOL) compared with aspheric monofocal IOL. Methods This was a prospective nonrandomized controlled study. Totally 114 consecutive senile cataract patients(114 eyes) were enrolled into this study. Fifty-seven cataract patients(57 eyes ) were implanted with ReZoom refractive multifocal IOL (ReZoom group), and another 57 cataract patients (57 eyes ) were implanted with aspheric monofocal IOL(Tecnis ZA9003 group). All the patients were assessed at 3 months postoperatively in the aberrations of crystalline, the modulation transfer function, contrast sensitivity of 10/100 percent in three sorts short distance(40, 63, 100 cm), uncorrected distanced visual acuity, uncorrected near visual acuity, bestcorrected distance visual acuity, best-corrected near visual acuity, distance corrected near visual acuity, pseudo-accommodation and the rate of offnear glasses. Results At 3 months postoperatively, both uncorrected near visual acuity and distance corrected near visual acuity were significantly better in ReZoom group than that in monofocal IOL group(P＜0.05). The accommodative range was(3.29±0.33）D in ReZoom group and(1.55±0.27）D in TecnisZA9003 group(P＜0.05). In 3/5 mm pupil diameter, the difference of the higher-total aberration between TecnisZA9003 group and ReZoom group was significant(P＜0.05); in 3 mm pupil diameter, the difference of the coma aberration between TecnisZA9003 group and ReZoom group was significant(P＜0.05). At 40, 63 cm and 100 cm, VA scores were higher in ReZoom group than that in TecnisZA9003 group(P＜0.05). The rate of off-near glasses in ReZoom group was better than in the aspheric monofocal IOL group(P＜0.05). The modulation transfer function at the spatial frequencies of 5, 10, 15, 20 cpd in ReZoom group were lower than that in Tecnis ZA9003 group(P＜0.05). Conclusion Compared with aspheric monofocal IOL, the ReZoom refractive multifocal IOL increase the higher-order aberration, but it can provide certain pseudo-accommodation, better useful near and middle distance visual acuity than aspheric monofocal IOL, especially for the patients who want to get rid of spectacles.
