[Proper understanding of aberration and scatter light and reasonable selection of IOL]

Along with the science and technology development, cataract surgery technology and the equipment as well as the IOL design and the technique of manufacture al had the considerable progress, cataract surgery had transformed into the refractive surgery gradually. The imaging quality of IOL eyes had influenced by the scatter light, the optical characters of the intraocular refractive mediums and the interactions among the different higher order aberrations. Therefore when choosing the IOLs, paying attention to many details and depending on the different sickness condition to carry on the personalized choice, can enhance sickness the degree od satisfaction.
