Effect of the exchanges of predominant eye on vision quality in patients after cataract surgery

Objective To analyze the effect of the exchanges of predominant eye on quality of vision in patients after cataract surgery. Methods A prospective study. The data of 516 eyes of 258 cases from Jun. 2015 to Jun.2016 were analyzed. All cases received phacoemulsification and intraocular lens implantation. The main predominant eye were determined with carving method. The visual acuity, contrast sensitivity and degree of satisfaction were observed before and 3 months after operation. Results At 3 months after operation, the predominant eye was exchanged in 69 cases(26.74%). The diopter of predominant eye and non-dominant eye were significantly decreased (P 0.05). There was no significant difference in degree of satisfaction between the two groups (P>0.05). Conclusion There is no significant effect of the exchanges of predominate eye on vision quality after cataract surgery. Key words: Surgery, cataract; Exchange, predominant eye; quality, vision
