Trial Outcomes & Findings for Toric Intraocular Lens Following Cataract Surgery (NCT NCT01140477)

NCT ID: NCT01140477

Last Updated: 2014-09-08

Results Overview

Percent reduction in absolute cylinder expressed as a percentage of the intended reduction in cylinder. Cylinder reduction is the measurement for astigmatism reduction. Astigmatism is a form of refractive error that can affect uncorrected visual acuity (at all distances). Reducing cylinder should improve UCVA, but other elements of refractive error, such as myopia or hyperopia, can also affect UCVA. Best corrected visual acuity (BCVA) is not affected by refractive error.

PRIMARY outcome

Timeframe: 120 - 180 day postoperative visit

Population: The analysis population only includes those for whom the outcome was measured within the specified time frame.

Percent reduction in absolute cylinder expressed as a percentage of the intended reduction in cylinder. Cylinder reduction is the measurement for astigmatism reduction. Astigmatism is a form of refractive error that can affect uncorrected visual acuity (at all distances). Reducing cylinder should improve UCVA, but other elements of refractive error, such as myopia or hyperopia, can also affect UCVA. Best corrected visual acuity (BCVA) is not affected by refractive error.

SECONDARY outcome

Timeframe: 120 - 180 day postoperative visit

Population: The analysis population only includes those for whom the outcome was measured within the specified time frame.

This Outcome Measure was evaluated for Crystalens Toric IOL arm only - Toric IOLs require precise alignment to correct astigmatism; control IOLs do not.
