Patients with 900 degree myopia can undergo surgery if they meet the surgical criteria, and the requirements for different surgical procedures vary. Less than 300 degrees of myopia is mild myopia, 300 to 600 degrees of myopia is moderate myopia, more than 600 degrees of myopia is high myopia, and more than 1,000 degrees of myopia is ultra-high myopia. 900 degrees of myopia belongs to high myopia, and it is not a contraindication to surgery, so it can be corrected by surgery if it meets the criteria for surgical correction. There are two types of myopia surgery, one is corneal laser cutting surgery and the other is intraocular lens implantation surgery. Myopia surgery requires patients to have stable myopia, age compliance, normal corrected visual acuity, as well as patients’ desire to remove lenses, and pre-surgical examination in line with the surgical standard. It is recommended that patients with high myopia visit regular hospitals to assess their condition and follow the doctor’s instructions for treatment.
