High myopia usually does not rebound after treatment with laser. Although high myopia is treated with laser, it may worsen due to continued prolonged close eye use. In the case of high myopia, myopia does not stabilize at a certain level in adulthood, and may continue to grow. Myopia surgery only corrects the current level of myopia. However, the subsequent increase in myopia will need to be corrected by glasses, but will not rebound to the original myopia. Even after myopia surgery, you need to protect your eyes, otherwise your myopia will increase and you will need to wear glasses further.
