A Comparison of Aspheric Toric Intraocular Lens (IOL) Implantation Versus Aspheric Non-Toric Lens Implantation
Study Details
Study Description
Brief Summary
The purpose of this study was to evaluate and compare uncorrected distance visual acuity measurement in pseudophakic subjects with bilateral implantation of an AcrySof IQ Toric Intraocular Lens (IOL) versus bilateral implantation of an AcrySof IQ IOL.

Experimental: Toric T3 - T9 AcrySof IQ Toric IOL surgically implanted in the capsular bag of the eye following cataract removal. Both eyes were implanted, with the second eye implanted at least 1 week after and within 1 month of the first eye. |
Device: Toric T3 - T9
Commercially available, acrylic, multifocal IOL intended to provide visual correction over the lifetime of the cataract patient

Active Comparator: IQ SN60WF AcrySof IQ IOL surgically implanted in the capsular bag of the eye following cataract removal. Both eyes were implanted, with the second eye implanted at least 1 week after and within 1 month of the first eye. |
Device: IQ SN60WF

Outcome Measures
Primary Outcome Measures
- Monocular Uncorrected Distance Visual Acuity (Monocular UCDVA) at Month 3 [Month 3]
Uncorrected visual acuity (i.e., visual acuity measured without spectacles or other visual corrective devices) was assessed using Early Treatment Diabetic Retinopathy Study charts at 100% contrast and measured in logarithm of the minimum angle of resolution (logMAR). Each eye was assessed, and both eyes contributed to the mean. LogMAR 0.00 is equivalent of 20/20 and LogMAR 1.0 is equivalent of 20/200. A more negative logMAR value would indicate a greater improvement in visual acuity.
