The dangers of laser treatment for myopia are that complications may occur

Many children will suffer from myopia because they do not develop good study habits and watch TV frequently. Some parents will choose laser treatment for myopia. In fact, laser treatment for myopia has advantages and disadvantages. The harm is that it is easy to cause some complications and affect future vision.

1. The disadvantages of laser treatment of myopia are mainly the following complications that may occur during and after the operation:

1. The corneal flap is off-center, poorly aligned, wrinkled, or has debris or blood residue between corneal layers;

2. The laser cutting is off-center and the corneal knife cuts through the cornea;

3. Lifelong glare and dizziness after surgery: more common in high myopia, with halos when looking at things;

4. Undercorrection or overcorrection: This situation requires another surgery, but the effect after the second surgery is not very ideal;

5. Vision rebound: Especially for patients with high myopia, vision begins to decline a few years after surgery;

6. Decreased best corrected visual acuity: after surgery, the visual acuity can no longer be achieved as it could be with glasses;

7. Difficulty reading, dry eyes, decreased corneal sensitivity, and pain;

8. Irregular astigmatism: Almost all patients have varying degrees of irregular astigmatism after surgery.

9. Corneal infection, diffuse interlaminar keratitis, formation of central corneal island:

10. Peripheral corneal degeneration or scar formation, and central corneal pigmentation.

Second, the advantages of laser treatment of myopia:

1. Laser treatment for myopia is highly accurate: the degree of correction is completely controlled by precision computers and laser instruments.

2. High safety: Generally, the surgery is performed on the front part of the cornea, so there is no damage to the corneal endothelial cells. There is no scab tissue left on the cornea after the surgery, and the chance of corneal opacity is small.

3. High stability: The degree of myopia after laser treatment is unlikely to change over time.

4. Short operation time: only local anesthesia is required on the eyes, the operation takes about three minutes, and laser correction takes only thirty seconds, and no hospitalization is required.

5. Relatively high comfort: There is no corneal epithelial cell defect, keratitis, pain, or photophobia after the operation.

6. Short recovery period: Vision will be stable within one to seven days after surgery

Warm reminder: To avoid complications and hazards of laser treatment for myopia, myopic patients must choose a regular hospital for surgical treatment and only proceed with the treatment after confirming that it can be performed.
