Wavefront Analisys and Contrast Sensitivity of Spherical and Aspherical Intraocular Lenses
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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)
