AIM: To investigate the change of corrected vision and stereo vision in anisometropic patients after laser in situ keratomileusis(LASIK).

METHODS: The clinical data of 84 cases of anisometropic children(84 eyes)were retrospective analyzed. The changes of corrected visual acuity and stereopsis of different gender, age, type of amblyopia in children anisometropic before treatment, after treatment for 3, 6mo and 1a were analyzed. The stereoscopic vision correction correlation were analyzed.

RESULTS: Corrected Log MAR visual acuity and stereopsis of 84 patients after LASIK surgery treatment for 3mo, and 1a later significantly decreased than before treatment(P<0.05). The corrected Log MAR visual acuity and stereopsis of male and female after treatment for 3, 6mo and 1a was not statistically significant(P>0.05). Corrected visual acuity of age <30 group for 3, 6mo and 1a was significantly lower than the age ≥30 group(P<0.05). After 3, 6mo and 1a stereo vision with hyperopic anisometropia amblyopia decreased more than that with myopic anisometropia amblyopia(P<0.05), but corrected Log MAR visual acuity after treatment was no statistically significant difference(P>0.05). Improved correctted vision of anisometropic patients after LASIK surgery had no connection with the decrease of stereo vision(P>0.05).

CONCLUSION: LASIK surgery can improve visual acuity in patients with anisometropia amblyopia, but the course of treatment of visual acuity and stereopsis affected by age and type of amblyopia.
