AIM: To investigate age-related cataract and its postoperative dominant eye changes and visual quality of patients.

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.
