The dangers of laser myopia

Myopia refers to myopia, laser myopia harm has dry eye disease, night vision decline, refraction regression, etc., specific analysis is as follows:

1. dry eye laser

myopia surgery will be operated on the corneal stroma, easy to damage to corneal tissue, local nerve fiber endings, resulting in reduced local tear secretion, causing dry eye disease.

2. night vision decline

laser myopia surgery if improper care, causing corneal edema, corneal interlayer debris, etc., will lead to visual impairment, causing night vision decline.

3. refraction regression

If laser myopia surgery, still do not pay attention to normal eyes, it will cause eye axis change, leading to refraction regression, vision rebound phenomenon.
