Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Uncorrected Distance Visual Acuity [ Time Frame: 6 months ]
    Uncorrected Distance Visual Acuity at month 6 measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

  • Best Corrected Distance Visual Acuity [ Time Frame: 6 Months ]
    Best Corrected Distance Visual Acuity at month 6 measured in LogMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

  • Residual Refractive Cylinder [ Time Frame: 6 Month ]
    Residual Refractive Cylinder at month 6 measured in diopters (D).

Secondary Outcome Measures:
  • Patient Satisfaction Survey [ Time Frame: 6 months ]
    Satisfaction for daytime distance vision, nighttime distance vision, and indoors distance vision on a scale of 1 to 5, with 1 being very dissatisfied and 5 being very satisfied.

Enrollment: 26
Study Start Date: June 2007
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
