Visual acuity, modulation transfer function (MTF), defocus curve, spectacle independence, and photic phenomena were analyzed 3 months postoperatively.Results: There was no significant difference between the two groups in binocular uncorrected visual acuity at distance. Mean binocular uncorrected visual acuity at intermediate (monovision: 0.81 dec; control: 0.58 dec) and near (monovision: 0.59 dec; control: 0.30 dec) were significantly better in the monovision group. In the monovision group, the difference of MTF values between the dominant and the non-dominant eyes was not statistically significant and MTF values were within the normal range for both eyes. Spectacle independence at intermediate and near was statistically significantly higher in the monovision group compared to the control group. The incidence of photic phenomena was similar in both groups.Conclusion: Micro-monovision implantation of TECNIS Symfony IOLs provided a superior range of visual acuity from far to near and higher spectacle independence compared to a control group targeted for emmetropia.Keywords: cataract, extended range of vision, defocus curve, spectacle independence, emmetropia, photic phenomenaTan JQin YWang CYuan SYe JDove Medical PressarticleTECNIS Symfonymicro-monovisiondefocus curvespectacle independencedominantOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1071-1077 (2019)
