【摘要】 目的评价白内障超声乳化摘除联合衍射型多焦点人工晶状体植入术后患者的视力及拟调节力。方法将40例(46眼)年龄相关性白内障患者随机分为2组,每组各20例(23眼),分别行白内障超声乳化摘除并植入ReSTORSA60D3衍射型多焦点人工晶状体(多焦组)和Natural SN60AT单焦点人工晶状体(单焦组),观察术后裸眼远、近视力,最佳矫正远、近视力,最佳视远矫正时近视力以及视近拟调节力。结果两组患者术后裸眼远视力,最佳矫正远视力和最佳矫正近视力差异均无显著性(P>0.05);术后第3个月裸眼远视力≥0.5者多焦组和单焦组均达95.65%。多焦组术后裸眼近视力和最佳视远矫正时近视力明显优于单焦组(P<0.05);术后第3个月裸眼近视力≥0.5者,多焦组为69.57%,单焦组为4.35%;而最佳视远矫正时近视力≥0.5,多焦组为69.57%,单焦组为13.04%。术后第3个月视近拟调节力多焦组为(-3.54±1.05)D,单焦组为(-1.65±0.68)D,差异有显著性(P<0.05)。结论ReSTOR衍射型多焦点人工晶状体能提供良好的远、近视力,拟调节幅度较单焦点人工晶状体大,能有效地提高白内障患者术后的视觉质量。更多还原

【Abstract】 Objective To evaluate visual quality and pseudoaccommodation in patients after the implantation of an apodized diffractive multifocal intraocular lens (MIOL). Methods Forty patients (46 eyes) with age-related cataract were divided into two groups. GroupⅠwas the multifocal group: 20 cases (23 eyes),ReSTOR SA60D3 MIOL was implanted after phacoemulsification; Group Ⅱ was the monofocal group: 20 cases (23 eyes),Natural SN60AT monofocal intraocular lens (SIOL) was implanted after phacoemulsification. Measurements were taken at 1 week and 3 months postoperatively,including uncorrected distance visual acuity (UCDVA),best-corrected distance visual acuity (BCDVA),uncorrected near visual acuity (UCNVA),best-corrected near visual acuity (BCNVA),distance-corrected near visual acuity (DCNVA) and pseudoaccommodation. Results UCDVA and BCDVA in the multifocal group were not statistically different from the monofocal group (P>0.05). The proportion of patients that achieved a UCDVA of 0.5 or better was 95.65% in both groups at 3 months postoperatively. UCNVA and DCNVA were statistically better in the multifocal group compared to the monofocal group (P<0.05). A higher proportion in the multifocal group achieved 0.5 or better uncorrected near visual acuity and 0.5 or better best distance-corrected near visual acuity than in the monofocal group (69.57% versus 4.35%,69.57% versus 13.04%). Compared to the monofocal group,the multifocal group had better pseudoaccommodation (P<0.05) (-3.54±1.05)D versus (-1.65±0.68)D. Conclusion The AcrysofReSTORapodized diffractive multifocal intraocular lens may provide excellent distance and near visual acuity,better pseudoaccommodation and improved quality of life for patients after phacoemulsification.更多还原
