Primary Outcome Measures:
  • Rotational Stability [ Time Frame: 6 Months post-surgery ] [ Designated as safety issue: Yes ]
    Average magnitude of intraocular lens (IOL) rotation from day of surgery to 6-months post-surgery, measured in degrees.


Secondary Outcome Measures:
  • Residual Refractive Cylinder [ Time Frame: 6 Months post-surgery ] [ Designated as safety issue: Yes ]
    The refractive astigmatism 6 months post-surgery, measured in diopters.
