Binocular uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) were also good in both groups without significant differences (UIVA IC-8 group 0.01 ± 0.07, Symfony group -0.01 ± 0.08, p-value 0.35; UNVA IC-8 group 0.14 ± 0.11, Symfony group 0.09 ± 0.08, p-value 0.14). Subjective satisfaction was high in both groups. CONCLUSION Both EDOF IOLs provided a very good UDVA with superior results in the IC-8 group, good UIVA and UNVA under photopic light conditions. Subjective patient satisfaction was higher in the IC-8 group.PURPOSE To report normative angle alpha orientation and magnitude distribution in a cataract surgery patient population. SETTING U.S. academic medical center. DESIGN Retrospective review. METHODS A total of 11 871 wavefront aberrometer/corneal topographer angle alpha measurements were performed over 40 months, yielding 8773 bilateral measurements (73.9%) with zero bad wavefront datapoints. The analysis was limited to the first right-eye scan for 3382 unique patients. The angle alpha magnitudes (millimeters) and orientations (degrees) were analyzed for these unique right eyes. RESULTS For the 3,382 unique patients, the mean angle alpha magnitude was 0.44 ± 0.15 mm (median, 0.44 mm; 25th and 75th percentiles 0.34 mm, 0.53 mm). Angle alpha orientation was predominantly horizontal (P less then .01), with a mean of 186 ± 32 degrees. The expected point of intraocular lens (IOL) centration (EPIC) based on the geometric center of the corneal limbus was temporal to the visual axis in 3212 eyes (95%), nasal in 92 eyes (2.7%),
