First of all, you must be examined in a regular medical institution to confirm what type of refractive error before correction. The current methods of correction are: 1, wearing frame glasses; 2, wearing corneal contact lenses (contact lenses); 3, medication; 4, surgery, according to the different parts of the surgery can be divided into keratoconus surgery, intraocular refractive surgery and scleral refractive surgery, which: keratoconus. Safe, effective, economical, and can be replaced with glasses as the refractive error changes. The correction effect is not ideal for patients with high myopia, refractive parallax, large astigmatism and mixed astigmatism; there are problems such as reduced visual field and vulnerability to trauma. Developing adolescent myopic patients should be reviewed semi-annually and have their lenses replaced regularly. Contact lenses are aesthetically pleasing and better than frames for patients with high myopia and refractive error. Long-term wear can cause corneal hypoxia and improper care, resulting in corneal neovascularization, conjunctival congestion, conjunctivitis, corneal epithelial damage and corneal infection and ulceration, which can lead to blindness in serious cases. Not suitable for adolescent myopic patients and myopic patients with poor working environment. Medication It can relieve the ciliary muscle fatigue of the eye and is effective for pseudomyopia. There is no definite effect on true myopia. It is suitable for pseudomyopia caused by ciliary muscle spasm. Surgical treatment Removal of glasses, good correction effect, wide range of indications. It is expensive and has some surgical risks. Suitable for myopic patients over 18 years old who want to remove their glasses and can afford the cost of surgery.
