Not Applicable

Completed

• Conditions: Cataract
• Interventions: Device: AcrySof® IQ ReSTOR® +3.0 D Multifocal IOL; Device: Monofocal IOL; Device: AcrySof® IQ ReSTOR® +3.0 D Multifocal Toric IOL

• Registration Number: NCT01290068
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this study is to assess and compare visual outcomes of the AcrySof® IQ ReSTOR® +3.0 D intraocular lens (IOL) to a commercially available monofocal IOL in cataract patients.

Detailed Description

This study included subjects with bilateral age-related cataracts and either no preoperative corneal astigmatism, or preoperative regular corneal astigmatism confirmed by autokeratometry of ≤2.5 D.

Primary Outcome Measures

Name	Time	Method
Proportion of Participants Reporting Spectacle Independence at All Distances	Month 6 after second eye implantation	Spectacle independence at all distances; ie, where type of spectacles used/prescribed equaled 'No spectacles', was evaluated. If for the 6-month visit, spectacle type information was missing for the spectacle independence endpoint, but the subject attended this 6-month visit, subject was assumed to be spectacle independent.
Percentage of Participants Classified as Responders	Month 6 after second eye implantation	Distance VA and near VA were measured binocularly (both eyes together) without visual correction using ETDRS (Early Treatment of Diabetic Retinopathy Study) charts positioned at a consistent, manufactured distance. VA was measured in logMAR (logarithm of the minimum angle of resolution), with a lower logMAR value indicating better visual acuity. A responder was defined as a participant who achieved bilateral uncorrected distance visual acuity and bilateral uncorrected near visual acuity of ≤0.1 LogMAR at the Month 6 visit.
Mean Vision-Related Quality of Life as Reported on the NEI-RQL 42 (5 Dimensions)	Month 6 after second eye implantation	Vision-related quality of life dimensions were evaluated using the National Eye Institute Refractive Error Quality of Life instrument (NEI-RQL 42), a self-administered questionnaire. Each dimension was scored between 0 to 100, with a higher score indicating a better vision-related Quality of Life. 5 of the dimensions were prespecified as primary.

Secondary Outcome Measures

Name	Time	Method
Median Total Spectacle Cost Prior to Any Reimbursement	Month 6 after second eye implantation	Total spectacle cost includes the frame, lens, and any reimbursement from national health systems or private insurance. Costs collected in pounds sterling were converted to euros.
