The harm of laser myopia: be alert to postoperative headache

First: myopia management surgery is to cut the cornea, change the corneal curvature and thickness, so that the focus of light accurately falls on the retina. But the regeneration effect of the organism itself is irresistible. Although the process of corneal regeneration is relatively slow, usually 2-3 years, at that time, it is like a piece of human epidermis has been cut off, and then slowly grows up, but the cornea is no longer smooth and glossy, becoming a mirror. What you see at this time is also deformed, leading to eye swelling, fatigue, headache and other uncomfortable symptoms.

Second: there is a balanced tension between the outer wall of the eyeball and its contents, which is called intraocular pressure. When the cornea of the eyeball is partially cut, the outer wall of the eyeball becomes thinner and the contents remain unchanged, so the intraocular pressure increases. Intraocular pressure can not be too high or too low, too high will cause glaucoma.

Third: the cornea should be transparent, so that the outside world can be reflected on the retina. There are no blood vessels on the cornea, and its metabolism is completed by the water-like eye fluid in the spongy tissue and the blood vessels around the cornea. After the cornea is covered by these proliferative blood vessels, the transparency will be obstructed, and the object will become blurred, especially the shadow.
