Patients with corneal spherical aberration ≤0.3 μm were implanted with a zero-spherical aberration advanced optics(AO) aspherical intraocular lens and those with corneal spherical aberration >0.3 μm received a Tecnis ZA9003 aspherical lens(-0.27 μm spherical aberration). Preoperative total remnant spherical aberration was estimated and actual total spherical aberration was measured 3months postoperatively. The consistency between preoperative and postoperative spherical aberration was analyzed by t-test,correlation analysis, and Blant-Altman plots.Results: The estimated and measured values of total spherical aberration were(0.189±0.151) μm and(0.141±0.131) μm,with a statistical difference(t=5.347,P},
