  Purpose
The objective of this study is to test the hypothesis that the time to reach a stable refraction is significantly shorter in eyes operated with the 1.8 mm coaxial microincision compared to eyes operated with the 2.75 mm standard incision using the Stellaris Vision Enhancement System.

Cataract Aphakia Procedure: Coaxial Micro-Incision Cataract Surgery Procedure: Coaxial Small Incision Cataract Surgery Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized

Primary Outcome Measures:
  • Refractive Stability [ Time Frame: 12 weeks ]
    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 ]
    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 ]
    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 ]
    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 ]
    Uncorrected visual acuity(UCVA) was assessed using logMAR charts. Change from baseline summarized by visit.

  • Surgically Induced Astigmatism (SIA) [ Time Frame: Visits 1-3 ]
    Surgically induced astigmatism was presented in dioptres at each visit.

  • Surgically Induced Astigmatism (SIA) [ Time Frame: Visits 4-8 ]
    Surgically induced astigmatism presented in dioptres at each visit.
