Myopia of 700 degrees is within the scope of laser corneal surgery, but whether or not a patient can undergo surgery is related to the patient’s eye condition, and if the patient meets the conditions of the surgery, then it is feasible to undergo surgery. Myopia is a common ophthalmic disease, a type of refractive error. The severity of myopia is categorized by the degree of myopia, and myopia above 600 degrees is defined as high myopia. Currently, myopia of 700 degrees is already considered high myopia, but it is still within the scope of the indications for laser myopia correction surgery. Patients need to go to the ophthalmology department of the hospital for corneal curvature, corneal thickness and other examinations before undergoing surgery. If these indexes meet the criteria for surgical treatment, then surgery can be performed to correct myopia and improve vision. However, if the thickness of the cornea is thin, it is not suitable for corneal laser surgery. It is recommended that children with myopia should consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions to choose the appropriate treatment.
