简要总结
Purpose:To compare visual performance, total and high order wavefront aberrations (coma, spherical aberration and other terms) and contrast sensitivity in eyes implanted with one monofocal aspheric intraocular lens (IOL) and two spherical IOLs (SofPort AO, Soflex,AcrySof®IQ (40 eyes), AcrySof®Natural and AMO®Sensar)
