[Abstract]:Objective: to investigate the changes of corneal posterior surface height within 1 year after correction of myopia by femtosecond laser in situ keratomileusis with Allegro Oculyzer anterior segment diagnostic system. Methods: Forty-five patients (90 eyes) with myopia were treated with femtosecond laser LASIK (preoperative equivalent spherical mirror -10.63 ~ 1.63 D). The diagnosis system of anterior segment of Allegro Oculyzer was used to diagnose myopia before and after operation. Three dimensional images of anterior segment were collected in 6 months and 1 year respectively. The height of the central posterior surface of the cornea and the thickness of the thinnest point of the cornea were measured and the difference of the height of the posterior surface of the cornea was calculated. ANOVA and Pearson correlation analysis were used. Results: there was no significant difference between femtosecond laser LASIK before and after the repeated measurement of corneal posterior surface height at different follow-up time points (F1. 50 P 0. 05). Femtosecond laser LASIK was used to analyze the difference of corneal posterior surface height between 3 months, 6 months and 1 year after operation. There was no significant difference (P 0.05). The analysis of variance of the thickness of the thinnest point of cornea at different follow-up time points before and after operation showed significant difference (F _ (369.10) P _ (0.01). There was no correlation between corneal posterior surface height and SE,AD,RBT,AP/TCT and "(corneal flap thickness) / preoperative corneal thinnest point thickness" at different follow-up time after femtosecond laser LASIK (P0.05). Conclusion: Femtosecond LASIK (Femtosecond LASIK) has good posterior corneal surface stability and no obvious change in corneal posterior surface height, and the thickness of the thinnest point increases gradually and becomes stable 3 months after operation.
