Intraoperative Aberrometry vs Conventional Intraocular Lens Calculation, a Prospective Study.
Sponsor: Instituto de Oftalmología Fundación Conde de Valenciana
Summary
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

Interventions
Intraoperative aberrometer
the 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
the intraocular lens in this group will be calculated preoperatively with Barrett Universal II formula
