5. Study Description

Brief Summary
The purpose of this study is to evaluate neutralization of keratometric astigmatism in patients with cataract and astigmatism higher than 1 diopter, with phaco surgery and the implantation of a toric intraocular lens.
Detailed Description
Patients with Cataract are treated with phacoemulsification of the lens with an implantation of an intraocular lens. Besides cataract, almost 25% of these patients have some degree of Astigmatism; when it is higher than 1 diopter, it is possible to neutralize it with an implantation of a toric intraocular lens.
