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
patients with senile cataract, patients undergoing phacoemulsification, complete biometric profile, axial length calculated by interferometer.
glaucoma, uncontrolled diabetic retinopathy, pseudoexfoliation syndrome, aged macular degeneration , dry eye syndrome, other ocular pathologies.
Parallel
Intraoperative aberrometer
Devicethe patient intraocular lens will be optimized during the aphakic period after cataract extraction and before intraocular lens implantation, this will produce a possible change in the dioptric power of the intraocular lens
Preoperative intraocular lens calculation
Other interventionthe intraocular lens in this group will be calculated preoperatively with Barrett Universal II formula
spherical equivalent
Spherical equivalent values at 90 days of the postoperative period
uncorrected distance visual acuity
uncorrected distance visual acuity at 90 days of the postoperative period
