Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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)
