Aniseikonia returns to baseline after second cataract surgery

Aniseikonia induced by cataract surgery did not cause statistically significant changes in visual symptoms, according to a study recently published in Optometry and Vision Science.
Rutstein and colleagues conducted a study to evaluate the relationship of anisometropia and aniseikonia as well as the effect of aniseikonia on vision.
Researchers assessed 17 patients who had bilateral cataract surgery. They measured visual symptoms, stereopsis, aniseikonia, refractive error, visual acuity and ocular alignment before surgery and at 4 weeks after the first and second surgery.
Results showed an increase in aniseikonia and poorer stereopsis after the first surgery, but a return to near baseline measurements after the second surgery.
"Although aniseikonia increased and stereopsis decreased between cataract surgeries, visual symptoms were not intensified," the authors concluded. "Aniseikonia induced by cataract surgery, at least in the short term, may not be a substantial problem for ametropic patients with prior normal binocular vision."
