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.

Refractive Stability
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.
Time frame: 12 weeks
Best Corrected Visual Acuity
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
Time frame: Visit 1, visit 2, visit 3, visit 4
Best Corrected Visual Acuity
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.
Time frame: visit 5, visit 6, visit 7, visit 8
Uncorrected Visual Acuity
Uncorrected visual acuity(UCVA) was assessed using logMAR charts. Change from baseline summarized by visit.
Time frame: Visit 1, visit 2, visit 3, visit 4
Uncorrected Visual Acuity
Uncorrected visual acuity(UCVA) was assessed using logMAR charts. Change from baseline summarized by visit.
Time frame: visit 5, visit 6, visit 7, visit 8
Surgically Induced Astigmatism (SIA)
Surgically induced astigmatism was presented in dioptres at each visit.
Time frame: Visits 1-3
Surgically Induced Astigmatism (SIA)
Surgically induced astigmatism presented in dioptres at each visit.
