【摘要】:目的对比白内障超声乳化术后植入非对称区域折射型多焦点人工晶状体(intraocular lens,IOL)(SBL-3)与可调节型IOL(Tetraflex HD)的视觉质量,并探讨区域折射多焦点IOL视近区域在眼内不同位置对视觉质量的影响。方法收集年龄相关性白内障患者,排除相关禁忌证,分别植入非对称区域折射型多焦点IOL(SBL-3)或可调节型IOL(Tetraflex HD),分为MIOL(Multifocal IOL)组、AIOL(Accommodating IOL)组、MIOL-1组。在48只眼中,MIOL组18只眼,AIOL组20只眼、MIOL-1组10只眼。术后1个月、3个月时分别检查患者裸眼远视力、裸眼近视力,最佳矫正远视力、最佳矫正近视力及远视力矫正下近视力。此外,在3个月时使用视觉质量分析系统(OQAS)评估患者斯特列尔比值(Strehl ratio,SR)、调制传递函数截止频率(Modulation Transfer Function Cut off,MTFCut off)及客观调节幅度,并进行比较。结果术后1个月时,MIOL组、AIOL组患者最佳矫正远视力下近视力结果分别为(0.39±0.14)log MAR,(0.48±0.13)log MAR,两者差异有统计学意义(P0.05),其余视力结果均无统计学差异(P0.05);MIOL组与MIOL-1组患者视力结果均无统计学差异(P0.05)。术后3个月时MIOL组、AIOL组两组患者间裸眼远视力及最佳矫正远视力、最佳矫正近视力差异均无统计学意义(P0.05)。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组的裸眼近视力(0.303±0.094)log MAR和远视力矫正下近视力(0.339±0.077)log MAR,差异均有统计学意义(均为P0.05);MIOL组与MIOL-1组患者视力结果均无统计学差异(P0.05)。术后3个月时,OQAS测得MIOL组和AIOL组SR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P0.05)。MIOL组与AIOL组调制传递函数截止频率(MTFCut off)之间差异无统计学意义(P0.05);MIOL组与MIOL-1组患者SR值、MTFcutoff及客观调节幅度之间对比差异均无统计学意义(P0.05)。结论非对称区域折射型MIOL与可调节型IOL在视觉质量及调节幅度方面具有差异性;区域折射多焦点IOL视近区域摆放位置对视觉质量无显著性影响。
[Abstract]:Objective to compare the visual quality of asymmetric area refraction multifocal intraocular lens (SBL-3) and adjustable IOL (Tetraflex HD) after phacoemulsification. The effects of regional refraction and multiple focus IOL on visual quality in different positions in the eye were discussed. Methods Age-related cataract patients were divided into MIOL (Multifocal IOL) group (, AIOL (Accommodating IOL) group) and MIOL-1 group (MIOL-1 group) after removing relevant contraindications and implanting asymmetric refracted multi-focus IOL (SBL-3) or adjustable IOL (Tetraflex HD),. In 48 eyes, 18 eyes in MIOL group, 20 eyes in AIOL group and 10 eyes in MIOL-1 group. At 1 month and 3 months after operation, the patients were examined for the uncorrected distant visual acuity, the uncorrected near visual acuity, the best corrected distant visual acuity, the best corrected near visual acuity and the distal corrected near visual acuity respectively. In addition, the visual quality analysis system (OQAS) was used to evaluate the ratio of Stryer (Strehl ratio,SR), the cutoff frequency of modulation transfer function (Modulation Transfer Function Cut off,MTFCut off) and the objective modulation amplitude at 3 months. Results at 1 month after operation, the results of best corrected near visual acuity in MIOL group and AIOL group were (0.39 卤0.14) log MAR, () 0.48 卤0.13) log MAR, (P0.05). There was no statistical difference in the other visual acuity results (P0.05). There was no significant difference in visual acuity between MIOL group and MIOL-1 group (P0.05). At 3 months after operation, the uncorrected far visual acuity and the best corrected far visual acuity were observed in MIOL group and AIOL group. There was no significant difference in the best corrected near visual acuity (P0.05) in the). MIOL group (0.245 卤0.079) log MAR, (, 0.279 卤0.074) log MAR, P 0.05). The near visual acuity of naked eyes (0.303 卤0.094) log MAR) was better than that of AIOL group (0.339 卤0.077) log MAR,) (P 0.05). There was no significant difference in visual acuity between MIOL group and MIOL-1 group (P0.05). At 3 months after operation, the SR values of MIOL group and AIOL group were 0.19 卤0.29 and 0.15 卤0.05, respectively, and the objective adjustment ranges were (2.72 卤0.49) D and (2.19 卤0.49) D, respectively. The difference between the two groups was statistically significant (P0.05). MIOL group and AIOL group modulation transfer function cut-off frequency (MTFCut off) difference was not statistically significant (P0.05); There was no significant difference between MIOL group and MIOL-1 group in SR, MTFcutoff and objective adjustment amplitude (P0.05). Conclusion there are differences in visual quality and adjustable amplitude between asymmetric regional refraction MIOL and adjustable IOL, and there is no significant effect on visual quality of regional refraction multi-focus IOL.
