Visual and Refractive Outcomes After Implantation of Aspheric IOLs With Different Dioptric Increments and Manufacturing
A Randomized Fellow-eye Controlled Clinical Trial to Compare the Visual and Refractive Outcomes Between Two Aspheric IOLs With Different Dioptric Increments and Manufacturing Tolerances in Patients Undergoing Bilateral Cataract Surgery

This study compares two intraocular lenses, the Softec HD and the Tecnis Z9002, used to replace the natural crystalline lens after cataract extraction. The variables compared include 1) the accuracy of targeted versus achieved refractive outcomes and 2) visual acuity outcomes three months after implantation.
