The advantage of laser treatment of myopia is that it can quickly restore vision.

Its disadvantage is that it may have side effects.

The possible side effects are as follows:

1. Undercorrection or overcorrection: It is the most common side effect, residual myopia after operation, or hyperopia caused by exceeding the expected correction degree. Depending on the situation, laser correction can be carried out again after the degree is stable.

2. photophobia: within 3 to 6 months after operation, the sensitivity to light increases, but it will gradually disappear after 6 months, and very few cases will last.

3. Glare or diplopia: It is more common in the early stage of surgery, especially when the pupil becomes larger at night, most of them will gradually disappear and a few will last.

4. Surgical complications: most of them are poor corneal flap cutting, such as incomplete or uneven cutting; As long as the corneal flap is reset, it can be restored, and it can be operated again after three months.

5. Poor epidermal healing: it is common in PRK and can be recovered by therapeutic contact lenses and artificial tears.

Wait, so consult a professional doctor before laser treatment of myopia, don't be blind.
