Condition 1: Stable myopia degree
The first condition for laser ophthalmic surgery is that the degree of myopia of the patient must be relatively stable. The stability of myopia degree can be confirmed by two consecutive years of glasses degree examination. If the degree of myopia has not changed significantly in the past two years, that is, it remains relatively stable, then patients can consider laser correction surgery.
The stability of myopia degree is related to the age of the patient. Generally speaking, the myopia degree of teenagers changes rapidly and is not suitable for laser correction surgery. The degree of myopia of adults is relatively stable, and it can be operated more safely.
In addition, if the degree of myopia has significantly increased in the past two years, laser correction surgery may not be suitable for patients, because the stability of the degree after surgery cannot be guaranteed, and it may need to be corrected again.
Condition 2: Healthy eyes
In addition to the stable degree of myopia, the health condition of the eye is also one of the important conditions for laser correction ophthalmic surgery.
First, patients should not have serious eye diseases, such as keratitis, glaucoma, etc. These diseases may affect the safety and effect of surgery, and may even lead to postoperative complications.
Secondly, the patient's cornea should reach a certain thickness. The thickness of cornea is very important for the safety and effect of surgery. If the cornea is too thin, it may become thinner after surgery, increasing its vulnerability; If the cornea is too thick, the effect of surgery may not be ideal.
In addition, the eye shape of the patient also needs to meet certain requirements. If the eyeball is too steep or too flat, the effect and safety of surgery may be affected.
Condition 3: physical health
To perform laser correction ophthalmic surgery, the patient needs to be in good overall condition.
Patients with some serious or chronic diseases, such as diabetes and autoimmune diseases, may increase the risk of surgery.
In addition, patients should not have an obvious allergy history, especially those who are allergic to cornea, eye drugs or surgical instruments, because drugs or instruments may be used in surgery, and allergic reactions may cause adverse effects on surgery.
Condition 4: mental health
Laser orthopaedic ophthalmic surgery is a surgery with high requirements for patients, so patients need to have good mental health.
The operation has certain risks, and patients need to have courage and confidence to face the possible complications or unsatisfactory results of the operation. At the same time, it is necessary to actively cooperate with the doctor's treatment and rehabilitation suggestions before and after the operation.
If the patient has obvious psychological problems such as anxiety and depression, it is recommended to decide whether to perform laser correction surgery after being evaluated by a psychologist.
Conclusion: In general, the conditions suitable for laser corrective ophthalmic surgery include stable myopia, eye health, physical health and mental health. Some patients may meet multiple conditions at the same time, while some patients may not be suitable for surgery. Therefore, before considering laser correction surgery, it is necessary to consult the doctor in detail for a comprehensive assessment and examination.
