Abstract:

Objective  To evaluate the change of wave-front aberration 6 months after iris-recognition combined with wave-front-guided LASIK and Planoscan-LASIK for myopic astigmatism. Methods  In this prospective contrast study,97 patients (194 eyes) with myopic astigmatism were divided into two groups: the Zyoptix group (49 patients, 98eyes) accepted iris-recognition combined with wave-front-guided LASIK and the  Planoscan group (48 patients, 96 eyes) accepted Planoscan-LASIK. By comparing the collected data of diopter and wave-front aberration of the two groups, the influence of the two kinds of operations on wave-front aberration were studied. Results  The preoperative refraction and wave-front aberration of the  Zyoptix  group and  the  Planoscan group were not significantly different  There were significant differences in refraction and wave-front aberration between the two groups 6 months after operation, but no significant differences were found in the 3rd coma aberration and spherical-degree. Conclusions  Iris-recognition combined with wavefront-guided LASIK for myopic astigmatism is superior to PlanoscanLASIK,
