Effect of dominant eye on balance function in age-related cataract patients

Abstract

AIM: To compare the effects of improving the dominant and non-dominant eye vision on the balance function of age-related cataract patients with a 3mo follow-up.METHODS: Totally 106 patients with age-related cataract underwent monocular surgery were recruited. According to whether the surgical eyes were dominant, cases were divided into two groups: the dominant eye group(50 cases)and the non-dominant eyes(56 cases). Balance function(Berg balance scale, timed “up and go”)were tested 1d before surgery and 3mo after surgery.RESULTS: The preoperative and postoperative Berg balance scale score changes were as followes: 50.08±4.92, 51.60±4.96, 1.52±1.14, in dominant eye group and 50.73±3.08, 51.67±2.65, 0.94±1.35 in the non-dominant eye group, there were no statistically differences in the first two items, and the amount of changes were statistically different(P=0.02). The preoperative and postoperative timed “up and go”were changed as these, 11.91±4.08s, 10.96±3.66s, 0.95±1.54s in dominant eye group, and 11.80±3.87s, 10.69±3.16s and 1.11±1.75s in non-dominant eye group, there were no statistically differences in the above three items(all P>0.05).CONCLUSION: There was no effect on the balance function between the improvement of the visual acuity on dominant and the non-dominant eye in the age-related cataract with a 3mo follow-up.
