Abstract:
PURPOSE: To observe the result of wavefront-guided (WFG) LASIK and investigate the ocular high order aberrations of WFG LASIK compare with conventional LASIK. METHODS: The uncorrected visual acuity (UCVA), manifest refraction, total high order aberration, coma and spherical aberration in 22 eyes of 13 patients who had undergone WFG LASIK were measured preoperative and at 1, 3 and 6 months postoperatively. The ocular high order aberrations of 19 eyes from 11 patients who had undergone convetional LASIK were measured at 6 months after surgery. The ocular high order aberrations of the WFG LASIK and conventional LASIK groups were compared. RESULTS: In the WFG LASIK group, the UCVA and spherical equivalent increased from 0.06 to 1.08 and from -6.13D to -1.16D, respectively after 6 months. The total high order aberration and coma (RMS) were 0.40 and 0.31 in conventional LASIK and 0.28 and 0.16 in WFG LASIK after 6 months. There was a statistically significant difference (p<0.05). CONCLUSIONS: The clinical outcomes of wavefront-guided LASIK by 6 months were a stable improvement in the visual acuity and a correction of all the optical aberrations of the eye. The postoperative high order aberration was significantly smaller than that in the conventional LASIK group.
