- W2361234749 abstract "Objective To analyze the visual quality after Toric intraocular lens( IOL) implantation with optical quality analysis system. Methods A total of 52 eyes of 44 patients with regular corneal astigmatism equal to or more than 1. 00 D underwent AcrySof Toric IOL implantation,based on the IOL types,the patients were divided into four groups,including 19 eyes in T3 group,18 eyes in T4 group,10 eyes in T5 group,5 eyes in T6 group. Main outcomes were evaluated at postoperative 3 months,included uncorrected distant visual acuity,corrected distant visual acuity,residual refractive cylinder and IOL rotation. Objective optical quality were measured using optical quality analysis system,included modulation transfer function( MTF) cutoff,objective scaltering index,Strehl ratio,MTF value under OV100%,OV20% and OV9%. Results At postoperative 3 months,the uncorrected distant visual acuity and corrected distant visual acuity were( 0. 18 ± 0. 11) LogMAR and( 0. 07 ± 0. 08) LogMAR,the residual refractive cylinder was( 0. 50 ± 0. 29) D,the mean absolute misalignment was 3. 62° ± 1. 76°,the mean MTF cutoff,OSI,Strehl ratio,MTF value under OV100%,OV20% and OV9% were( 22. 862 ± 5. 584) c·d- 1,1. 800 ±0. 840,0. 155 ±0. 038,0. 760 ±0. 180,0. 770 ±0. 190 and 0. 780 ±0. 210,respectively. The residual refractive cylinder in T3 group,T4 group,T5 group and T6 group were( 0. 34 ± 0. 28) D,( 0. 47 ± 0. 24) D,( 0. 57 ± 0. 19) D and( 0. 90 ± 0. 29) D,respectively,there was statistical difference( P 0. 01). Conclusion The optical quality analysis system is useful for comprehensively and objectively evaluating the optical quality of AcrySofToric IOL implantation. Implantation of an AcrySof Toric IOL is an effective and safe method to correct corneal astigmatism during cataract surgery." @default.
