摘　　要：目的对比植入非对称区域折射型多焦点人工晶状体(multifocal intraocular lens,MIOL;SBL-3)与可调节型IOL(accommodating IOL,AIOL;Tetraflex HD)后的视觉质量。方法前瞻性队列研究。选取在我院诊断为单纯性白内障,并行白内障超声乳化联合IOL植入术的患者26例(38眼)为研究对象,其中植入SBL-3 MIOL者18眼为MIOL组,植入Tetraflex HD AIOL者20眼为AIOL组。术后1个月、3个月分别检查患者裸眼远、近视力,最佳矫正远、近视力及远视力矫正下近视力,3个月时使用视觉质量分析系统评估患者斯特列尔比率、调制传递函数截止频率(MTFcutoff)值及客观调节幅度。采用SPSS 18.0分析数据。结果术后3个月时两组患者间裸眼远视力及最佳矫正远、近视力差异均无统计学意义(均为P>0.05);MIOL组裸眼近视力及远视力矫正下近视力分别为(0.245±0.079)log MAR、(0.279±0.074)log MAR,均优于AIOL组的(0.303±0.094)log MAR和(0.339±0.077)log MAR,差异均有统计学意义(均为P<0.05);术后3个月时,视觉质量分析系统测得MIOL组和AIOL组斯特列尔比率值分别为0.19±0.29和0.15±0.05,客观调节幅度分别为(2.72±0.49)D和(2.19±0.49)D,两组相比差异均有统计学意义(均为P<0.05)。结论非对称区域折射型MIOL与AIOL在视觉质量方面具有差异性。Objective To compare the intraocular optical quality between refrac- tive rotationally asymmetric multffocal hltraocular lens （ MIOL; SBL-3 ） and accommodat- ing IOL （AIOL, TetraflexHD ）. Methods Prospective comparative nonrandomized consecutive case series. Consecutive cataract patients were implanted of a refractive ro- tationally asymmetric MIOL （ SBL-3 ） or a AIOL （ TetraflexHD ）. Of the 25 cases （ 38 eyes）, 18 eyes were in MIOL group and 20 eyes were in AIOL group. The uncorrected distant and near visual acuity,best corrected distant and near visual acuity, distant-cor- rected near visual acuity were measured at 1 month, 3 months after surgery. SR, MTF cutoff and objective pseudoaccommodation range were evaluated at 3 months by optical quality analysis system （OQAS） postoperatively. The data was analyzed by SPSS 18.0. Results At 3 months postoperatively,there was no significant difference in the uncor- rected distant visual acuity, best corrected distant visual acuity and corrected near acui- ty between two groups （ P 〉 0.05 ）. Ucorrected near visual acuity and distance-corrected near visual acuity in MIOL group were （ 0. 245 ± 0. 079 ） logMAR, （ 0. 279 ± 0. 074 ） log- MAR,respectively,which were better than the AIOL group（0. 303 ± 0. 094 ）logMAR and （0. 339 ± 0. 077） logMAR, there were significant differences between groups （ all P 〈 0. 05）. At 3 months postoperatively, SR in MIOL group and AIOL group evaluated by OQAS were 0.19 ± 0. 29 and 0.15 ± 0.05, respectively, the objective pseudoaccommoda- tion range were （ 2.72 ± 0.49 ） D and （ 2.19 ± 0.49 ） D, respectively, there were significant differences between two groups （ all P 〈 0.05 ）. Conclusion There are differences in intraocular optical quality between rotationally asymmetric MIOL and AIOL.
