Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Study hypothesis: the implantation of an intraocular lens (IOL) with a modified addition at lens plane (restor +3, Alcon Laboratories,Inc) results in better intermediate visual acuity with similar distance and near visual acuity after cataract surgery.
