Abstract Details


To assess the long-term refractive results and changes of pachymetry after myopic LASIK depending on initial degree of myopia


S. Fyodorov IR&TC “Eye Microsurgery”, St.Petersburg branch, Russian Federation


The study included 48 patients (89 eyes) with different degree of myopia before LASIK. Follow-up was 10.1±1.9 years. Middle age at the time of investigation was 35.2±5.4 years. LASIK was made by standard method using Zeiss excimer lasers and Moria keratomes. US devices were used for pachymetry


In 10 years after LASIK for correction low, moderate and high myopia there is the increase in corneal thickness at 70.9%, 62.3% and 48.9% of the depth of ablation (p<0.05). Regression of refractive outcomes occurred in 62.5% of patients with initial moderate myopia (regression on average -1.2 ± 0.5D) and in 65.6% patients with initial high myopia (regression on average -2.27 ± 1.05D) (p<0.05). Refractive regression was negatively correlated with the increase in corneal thickness (r=-0.4; p<0.05)


In 10 years after LASIK there is a significant increase in corneal thickness in patients with any degree of initial myopia. This process can be a cause of refractive regression
