In order to investigate stereopsis, aniseikonia, and associated symptoms, the study examined bilateral pseudophakia with and without anisometropia. Patients with senile cataracts who had previously been scheduled for phacoemulsification with an IOL implant in both eyes were included in this cross-sectional study. Patients were split into two groups: the control group (n = 69) and the anisometropia group (n = 42), who had interocular post-surgical refraction differences of SE 1.00 D and SE 1.0 D, respectively. The statistical analysis of the data employed regression analysis, multivariate analysis, and univariate analysis models. An negligible difference (p = 0.766) separated the cataract surgery-induced aniseikonia in the control group (0.64% 1.41%) from the anisometropia group (0.62% 1.76%). The stereoacuity value was 1.95 0.17 log. revealed a significant difference (p 0.0001) between 2.12 0.22 log10 seconds of arc in the anisometropia group and 10 seconds of arc in the control group. With a negligible difference (p = 0.387), the mean score of symptoms related with aniseikonia was 1.41 0.46 in the control group and 1.47 0.45 in the aniso- metropia group. Axial length difference (18.06 percent), refractive error difference (44.53 percent), aniseikonia (25.71 percent), and IOL power difference all played independent roles in the anisometropia group's stereopsis prediction (11.71 percent). The study showed that stereopsis, aniseikonia, or other associated symptoms were not significantly worse in bilateral pseudo-dophakia with anisometropia smaller than 3D.
