Abstract Details


The purpose of this study is to evaluate whether eye dominance may change after bilateral cataract surgery.


Department of Ophthalmology, Konkuk University Medical Center, Seoul, Republic of Korea.


We retrospectively reviewed 51 patients who had undergone bilateral cataract surgery. All patients were examined for uncorrected distant visual acuity (UCDVA), corrected distant visual acuity (CDVA), eye dominance by hole-in card test and stereopsis prior to surgery and 2 month after surgery. We divided the patients into two groups (changed and unchanged eye dominance) and compared the characteristics between two groups.


The study included 51 patients with a mean age of 71.6�Â�±13.3 years. Twenty eight patients (54.9%) had right eye dominance before surgery. Thirty two patients (62.7%) had no change and 19 patients (37.3%) had change in eye dominance after surgery. Changed eye dominance group shows younger age (67.8 vs. 73.8 years) and more female patients (16/19 vs. 21/32) than unchanged group. Other features were not different between the two group.


In this study, significant number of patients (37.3%) show a change in eye dominance after bilateral cataract surgery. It seems that eye dominance has plastic characteristics and its plasticity may be related to age and sex. .Considering its plasticity, dominance of the eye is not likely to be an important factor in procedure such as monovision surgery.
