Conclusion: the selection of refractive surgery in patients with myopia should be based on age, condition of the lens, degree of myopia, and monocular and binocular refraction.
Objective: to observe the effect of concave and convex on growing and the refractive developing of guinea pig eyes and to establish lens-induced animal model of myopia or hyperopia.
