How to treat astigmatism myopia
summary
Myopia astigmatism treatment, myopia astigmatism correction method, mainly wearing glasses and laser surgery. The main symptoms of myopic astigmatism are similar to other ametropic symptoms, including vision loss, eyestrain, sore eyes, headache and so on. Astigmatism myopia how to treat tell you.
How to treat astigmatism myopia
First: the laser treatment of myopia is the current international popular myopia correction technology, with its high safety and good postoperative effect is popular all over the world. Laser myopia surgery is a combination of computer, laser and biomedical engineering technology. It can accurately cut the anterior corneal tissue by using cold laser without thermal damage. The excimer laser wave length, does not damage the periocular tissue, has high accuracy, strong predictability, good stability and other characteristics, is one of the most ideal programs for the correction of myopia.
Second: astigmatism is caused by the different ability of the eyeball to bend light in different directions. Myopic astigmatism can be divided into simple myopic astigmatism and compound myopic astigmatism: 1. When the parallel light on a main meridian is imaged on the retina, and the parallel light on another meridian perpendicular to it is focused in front of the retina, we call this refractive state simple myopic astigmatism. 2. If two main meridians which are perpendicular to each other are imaged in front of the retina, but their refractive power is not equal, we call this myopic astigmatism compound myopic astigmatism.
Third: whether it is simple myopic astigmatism or compound myopic astigmatism, you can improve your vision by wearing cylindrical lenses after optometry. There are many reasons for myopic astigmatism. The main reason for regular astigmatism is the curvature of corneal surface in different degrees. Most of them are congenital factors, and the degree of astigmatism is large. Some mild astigmatism is only about 0.25D, it may be the result of upper eyelid compression of the eyeball, belongs to the physiological range, generally does not need correction.
matters needing attention
Patients with mild myopic astigmatism, as long as there is visual fatigue and vision loss, must wear glasses correction.
