Primary Outcome Measures:
  • Refractive Stability [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Cumulative portion of eyes achieving refractive stability within 0.5 D of the final value for the remainder of the trial by surgical procedure and visit.


Secondary Outcome Measures:
  • Best Corrected Visual Acuity [ Time Frame: Visit 1, visit 2, visit 3, visit 4 ] [ Designated as safety issue: No ]
    Best corrected distance visual acuity(BCVA) was assessed using logMAR charts. Change from preoperative visit summarized by visit. A minus change represents an improvement of the visual acuity

  • Best Corrected Visual Acuity [ Time Frame: visit 5, visit 6, visit 7, visit 8 ] [ Designated as safety issue: No ]
    Best corrected distance visual acuity(BCVA) was assessed using logMAR charts. Change from baseline summarized by visit. A minus change represents an improvement of the visual acuity.

  • Uncorrected Visual Acuity [ Time Frame: Visit 1, visit 2, visit 3, visit 4 ] [ Designated as safety issue: No ]
    Uncorrected visual acuity(UCVA) was assessed using logMAR charts. Change from baseline summarized by visit.

  • Uncorrected Visual Acuity [ Time Frame: visit 5, visit 6, visit 7, visit 8 ] [ Designated as safety issue: No ]
    Uncorrected visual acuity(UCVA) was assessed using logMAR charts. Change from baseline summarized by visit.

  • Surgically Induced Astigmatism (SIA) [ Time Frame: Visits 1-3 ] [ Designated as safety issue: No ]
    Surgically induced astigmatism was presented in dioptres at each visit.

  • Surgically Induced Astigmatism (SIA) [ Time Frame: Visits 4-8 ] [ Designated as safety issue: No ]
    Surgically induced astigmatism presented in dioptres at each visit.
