简要总结

The purpose of this study is to evaluate the effect that placement and power of the AcrySof Toric has on post-operative visual acuity and spectacle independence for distance vision. This will be determined by comparing manifest refraction pre-operatively and post-operatively and by evaluating the rotational stability of the lens over time.

结局指标

主要结局

Visual Acuity (VA)

时间窗: Pre-operative, 1 month, 3 month, and 6 month post-operative

Pre-operative and 1 month, 3 month, and 6 month post-operative visual acuity (VA) measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". It is a unit of measure for visual acuity (VA).

次要结局

  • Spectacle Independence(6 months post-operative)
  • IOL Rotation(6 months post-operative)
