With curvature 45, if the length of the eye axis exceeds 23 millimeters, then myopia is likely to occur. With constant curvature, the greater the likelihood of myopia will be if there is persistent growth in the eye axis. But there is no equivalent conversion between the two. The curvature and the length of the eye axis is only a parameter of the degree of myopia of the eye, and it is not possible to determine whether the eye is myopic or not, or even the exact degree of myopia, based on the curvature value and the length of the eye axis. If the patient needs to determine the correct refractive state of the eyes, it is recommended to go to the hospital or regular examination institutions for standardized medical optometry, through the measurement of the refractive error of the eyeballs, to obtain the accurate myopia.
