方法：选取2013-01/2014-11在我院治疗的年龄相关性白内障患者102例204眼，根据术前最佳矫正视力(BCVA)分为两组，其中双眼BCVA差别≥2行者78例156眼为A组，双眼BCVA差别≤1行者24例48眼为B组，于术前及术后1，3mo进行优势眼检测，以及对比敏感度检查和视觉满意度调查。

结果：术前优势眼矫正视力为0.34±0.11，明显高于非优势眼(0.15±0.09)，差异有统计学意义(P<0.05)； 术后1，3mo优势眼与非优势眼矫正视力比较差异无统计学意义(P>0.05)； A组术后3mo有17眼发生优势眼转变，转变率为21.79%(17/78)，B组术后3mo有5眼发生优势眼转变，转变率为20.83%(5/24)，两组差异比较无统计学意义(P>0.05)； 优势眼发生转变组和未转变组患者不同空间频率对比敏感度检查差异无统计学意义(P>0.05)； 术后3mo视觉满意度问卷调查显示，A组评分为91.35±10.26分，B组评分为90.15±9.75分(P>0.05)，优势眼发生转变组评分为90.08±9.77分，未转变组评分为91.43±10.22分，差异无统计学意义(P>0.05)。

结论：年龄相关性白内障术后存在优势眼转变，但对视觉质量无影响。

METHODS: Totally 102 patients(204 eyes)with age-related cataract in our hospital from January 2013 to November 2014 were selected, and according to preoperative best corrected visual acuity(BCVA)were divided into two groups, in which the both eyes BCVA difference ≥2 lines(78 cases, 156 eyes)was group A, and both eyes BCVA difference ≤1 line(24 cases, 48 eyes)was group B. Dominant eyes were detected preoperatively and at postoperative 1 and 3mo. Contrast sensitivity and investigated visual satisfaction were tested.

RESULTS: Preoperative dominant eye corrected visual acuity was 0.34 ± 0.11, significantly higher than that of the non-dominant eye(0.15 ± 0.09), and there was statistically significant difference(P<0.05); At postoperative 1 and 3mo,between corrected visual acuity difference dominant eyes and the non-dominant eyes was not statistically significant(P>0.05); At postoperative 3mo, 17 cases in the group A had dominant eye changes, and change rate was 21.79%(17/78). At postoperative 3mo, the dominant eye change rate in the group B was 20.83%(5/24), and there was no statistical significant difference between the two groups(P>0.05). The dominant eye change group and non-change groups patients with different spatial frequency contrast sensitivity test showed no statistical significance(P>0.05), Postoperative 3mo after operationvisual satisfaction questionnaire display, score of group A was(91.35±10.26)points, score of group B was(90.15±9.75)points(P>0.05), the dominant eye change group score was(90.08±9.77)points, score non-change group was(91.43±10.22)points(P>0.05).

CONCLUSION: The dominant eye changes exist in postoperative eyes with age-related cataract, but there is no effect on visual quality.
