The recovery period for myopia surgery is usually about six months, because myopia is operated on the cornea. At present, excimer laser or semi-femtosecond laser are used to cut the corneal flap, and laser scanning is performed under the flap. However, the stromal growth period is longer because it takes longer to cut off the collagen fibers, which must be rebuilt through collagen growth and structure. Therefore, excessive sports activities are prohibited for six months, and the patient should not be hit by external forces on the eye, if the eye is hit, the corneal flap may still be displaced or dislodged.
