目的：比较提高优势眼视力和非优势眼视力对年龄相关性白内障患者术后3mo平衡功能的影响。

方法：纳入单眼手术的年龄相关性白内障患者106例106眼，根据术眼是否为优势眼分为优势眼组(50例)和非优势眼(56例)，记录术前1d和术后3mo时的平衡功能(Berg平衡量表分值和“站起-走”计时)。

结果：两组患者术前和术后Berg平衡量表分值及其改变量：优势眼组50.08±4.92、51.60±4.96、1.52±1.14分，非优势眼组50.73±3.08、51.67±2.65、0.94±1.35分，两组改变量有差异(P=0.021)。两组患者术前和术后“站起-走”计时及其改变量：优势眼组11.91±4.08、10.96±3.66、0.95±1.54s，非优势眼组11.80±3.87、10.69±3.16、1.11±1.75s(均P>0.05)。

结论：提高优势眼和非优势眼视力对年龄相关性白内障患者术后3mo平衡功能没有影响。

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.
