Hello. Choosing myopia surgery suggests that you choose a local professional eye hospital to better ensure the success of myopia surgery and prevent the occurrence of sequelae of myopia surgery. The myopia degree of 400 degrees is within the correction range of myopia surgery. However, myopia surgery requires higher eyes and congenital conditions for myopia patients.

1. Age and degree requirements

Femtosecond laser surgery, the age must be limited to 18-55. People over the age of 55 can have an examination to determine whether they can be operated. In addition, the degree should be within myopia 1200 degrees and astigmatism within 600 degrees. Farsightedness is within 600 degrees, and the degree is stable within two years.

2. Corneal thickness should be appropriate.

Femtosecond laser has changed the traditional way of making corneal flap. It is safer to use laser all the time without a knife, but it also requires the corneal thickness of the operator, which should be no less than 450 microns.

3. No eye diseases and systemic diseases.

Eye health is the key to myopia surgery. Myopia patients need inactive eye diseases, such as dry eye, exophthalmos and eyelid insufficiency, glaucoma, monocular patients, ocular inflammation, amblyopia, cataract, fundus lesions and so on. In addition, there are no restrictive diseases such as autoimmune diseases and diabetes.

4. The cornea is in good condition.

For example, if you wear contact lenses, stop using soft lenses 1 week, stop using hard lenses for 3 weeks, and stop using OK lenses for more than 3 months.

I hope these suggestions can be adopted by you ~ thank you ~
