Abstract
Objective: To evaluate the correlation factors for posterior corneal curvature after myopic LASIK.
Methods: The retrospective study of 92 eyes which underwent myopic LASIK was conducted. All LASIK procedures were done using Hansatome ® Microkeratome and Tecnolas ® 217 excimer laser (B&L, USA). Pre- and post-operative data were collected including refraction, corneal thickness, anterior and posterior corneal curvature measured by Orbscan ® Corneal Topography. Statistical analysis was done to evaluate the posterior corneal curvature related to other factors.
Results: The posterior corneal curvature after myopic LASIK showed low to moderate correlation to the amount of myopia treated (R2 = 0.286), anterior corneal curvature (R2 = 0.37) and corneal thickness (R2 = 0.37 for measured corneal thickness and R2 = 0.40 for calculated corneal thickness which is calculated by subtracting ablation depth from pre-operative thickness) (all p value < 0.05).
Conclusion: The posterior corneal curvature after myopic LASIK can be partially correlated with corneal thickness, anterior corneal curvature and the amount of myopia treated.
