AIM:To evaluate the consistency change between the dominant eye and non-dominant eye after LASIK.METHODS: A retrospective study of 74 eyes of 37 cases who had underwent myopic LASIK were divided into 3 groups:group one, the vision of the dominant eye was equal the other eye’s; group two, the vision of the dominant was better than the other eye’s; group three, the vision of the dominant was worse than the other eye’s. All the cases were the best-corrected visual acuity before the operation and the follow-up period was after the operation 1 day, 1 month, 3 months and 6 months. The results were compared and analysed.RESULTS: The consistency of the preoperation were not statistically different from that of other postoperation except the one after the surgery 1 day.CONCLUSION: LASIK does not change the consistency of the balance among the dominant eye and the non-dominant eye.
