The number of myopic patients is increasing year by year, which is related to current living habits to a certain extent. Nowadays, people use mobile phones and computers for long periods of time. The schoolwork load of children has also increased significantly compared with the past. Coupled with incorrect study postures, these are all acquired factors contributing to myopia.

In addition, myopia is divided into two types: physiological myopia and pathological myopia. In physiological myopia, the anteroposterior diameter of the eyeball is normal, and it is acquired. The main reason for its formation is the unscientific use of eyes as mentioned above, and it can be corrected by wearing glasses.

Pathological myopia, on the other hand, is caused by the increase in the anteroposterior diameter of the eyeball. Myopia will continue to worsen as the anteroposterior diameter of the eyeball lengthens. At the same time, it will also cause related lesions in the fundus retina. Simply wearing glasses cannot improve vision to the normal standard. To control the development of this pathological myopia, we can effectively control its development through surgical intervention.
