Myopia can usually be treated by corneal refractive surgery and IOL implantation. The sequelae of different surgical procedures are different, laser corneal refractive surgery may have sequelae such as overcorrection and dry eye, and the sequelae of IOL implantation are not yet clear. 1. Keratoconus surgery: This treatment includes non-laser keratoconus surgery and laser keratoconus surgery. Before undergoing this surgery, patients should be fully informed of the sequelae and precautions, and patients may experience sequelae such as dry eye, glare, halo, overcorrection, undercorrection, and so on. 2. IOL implantation: this treatment is suitable for patients with stable refractive status. Early cataract, glaucoma, and patients with large pupil diameter are not allowed to undergo this procedure, and sequelae such as iris inflammation and corneal edema may occur. It is recommended that myopic patients visit a professional medical institution in time and choose the appropriate treatment mode under the guidance of physicians.
