title: The effect of cataract surgery on ocular dominance.
abstract: OBJECTIVE
  The aim of this study is to assess whether eye dominance may change after cataract surgery.
  
  
  METHODS
  This is a prospective case series. Cataract surgery candidates were examined prior to surgery for best-corrected visual acuity, eye dominance, and handedness. Patients with ocular conditions that may affect visual acuity were excluded from the study. A month following surgery, best-corrected visual acuity and eye dominance examinations were repeated.
  
  
  RESULTS
  The study included 33 patients with a mean age of 70.5±9.4 years. Eighteen patients (54.5%) had right eye dominance. Following surgery, seven patients (21.2%) had a change in eye dominance. The change in dominance was linked to improved visual acuity in the operated eye and to a younger age, although with no statistical significance.
  
  
  CONCLUSIONS
  This is the first study reported in the literature to show that ocular dominance is a plastic characteristic following cataract surgeries. The results may change the importance given to eye dominance measurement prior to surgeries that rely on this examination, such as monovision surgeries.
