简要总结
the goal of this intervention study is to compare prospectively the accuracy of the power calculation between both groups, the intraoperative aberrometry (ORA) vs barrett universal II preoperative calculation (control group) .
Researchers will compare ORA group vs control to see changes in spherical equivalent and uncorrected distance visual acuity
详细描述
Studies have described a small difference between ORA (intraoperative aberrometer) and preoperative calculation with latest generation formulas ( Barrett Universal II ), the investigators intend to compare both groups prospectively, during the process randomization and blinding of the participants will be made.
The investigators will report spherical equivalent and uncorrected distance visual acuity values at 90 days of the postoperative period.
