Use of Toric Intraocular Lens to Neutralize Keratometric Astigmatism

Not Applicable

Terminated

• Conditions: Cataract; Astigmatism
• Interventions: Procedure: Acrysof Toric one-piece intraocular lens

• Registration Number: NCT00925886
• Lead Sponsor: Asociación para Evitar la Ceguera en México

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.
