Arm Intervention/treatment
Experimental: wavefront-guided LASIK Device: LASIK correction of hyperopic refractive errors
Surgeons will perform wavefront-guided LASIK based upon measurement obtained with the iDesign System

Primary Outcome Measures :
  1. Line loss for Best Spectacle Corrected Visual Acuity (BSCVA) [ Time Frame: 9 Months ]
    <5% of eyes with a loss of > 2 lines of Best Spectacle Corrected Visual Acuity

Secondary Outcome Measures :
  1. Uncorrected Visual Acuity (VA) 20/40 or better [ Time Frame: 9 Months ]
    85% of eyes with uncorrected visual acuity of 20/40 or better
