Not Applicable

Recruiting

• Conditions: Cataract

• Registration Number: NCT02678962
• Lead Sponsor: Wenzhou Medical University

Brief Summary

The purpose of this study is to compare and evaluate the clinical outcomes of 6 kinds of Multifocal Intraocular Lenses: SN6AD1, SBL-3, LS-313 MF30, AT LISA tri 839 MP, ART, LS-313 MF30T.

Detailed Description

This study is a prospective randomized controlled trial to compare and evaluate the clinical outcomes of 6 kinds of Multifocal Intraocular Lenses, the outcome measurements include postoperative visual acuity, visual quality and complications. Patients enrolled in the study will be randomized to receive one of the Multifocal Intraocular Lenses mentioned above, and the clinical outcomes of each Multifocal Intraocular Lens will be assessed at several visits: 1 day, 1 week, 1 month, 3 months and months post-operatively.
