[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 鹵0.14) log MAR, () 0.48 鹵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 鹵0.079) log MAR, (, 0.279 鹵0.074) log MAR, P 0.05). The near visual acuity of naked eyes (0.303 鹵0.094) log MAR) was better than that of AIOL group (0.339 鹵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 鹵0.29 and 0.15 鹵0.05, respectively, and the objective adjustment ranges were (2.72 鹵0.49) D and (2.19 鹵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.
