You need to know these contraindications of myopia surgery!

There are certain "physical indicators" required for myopia surgery. In order to maintain your health and obtain excellent postoperative results, it is necessary and important to pay attention to whether you meet the surgical indications. If your physical condition is not suitable, do not force yourself to take off your glasses.

Before the operation, a medical record is created, medical history is inquired, and more than 20 preoperative examinations are performed in order to conduct a detailed investigation of the disease. Eye data can be obtained through examination, while problems such as systemic connective tissue diseases or immune diseases need to be known by oneself.

For the sake of health and safety, please cooperate and answer truthfully when the nurse asks you about your illness. Do not hide anything.

People with active inflammatory lesions of the eyes: such as acute conjunctivitis, keratitis, blepharitis, dacryocystitis, etc.

Suffering from eye diseases such as keratoconus, glaucoma, cataracts, dry eyes, and corneal endothelial degeneration.

I have had retinal hemorrhage and retinal detachment.

Amblyopic patients with corrected visual acuity less than 0.5.

Severe myopia, pupil diameter is too large, cornea is too thin, that is, corneal thickness is less than 460μm (micrometers), and corneal curvature exceeds the range of 39.00D-48.00D.

Surgery is not recommended for adolescents under the age of 17 whose cornea is still developing and whose refractive power will change.

It is also not recommended for people over 55 years of age, as refractive errors can be corrected with an intraocular lens at the same time as cataract surgery.

Patients with progressive myopia whose refractive power is unstable (increase of more than 50 degrees within 1 year and more than 100 degrees within 2 years).

Patients with diseases that affect corneal wound healing, such as scar constitution, diabetes, rheumatoid arthritis, etc.

People who have mental illnesses such as anxiety and depression and are taking medication.

Female patients cannot undergo surgery during pregnancy and lactation.

In order to obtain accurate eye data during the preoperative examination, if you are wearing contact lenses, you need to stop wearing them in advance. Soft lenses (ordinary contact lenses and cosmetic lenses) should be discontinued for 1 week, RGP lenses should be discontinued for 1 month, and orthokeratology lenses should be discontinued for 3 months.

If there are no contraindications to surgery, and the preoperative eye examination data meets the surgical conditions, you can make an appointment to remove your glasses.
