For astigmatism, it is important in daily life to consume a diet rich in proteins, vitamins, and carotenes, such as meat, eggs, dairy, various fresh fruits and vegetables, and carrots. It is advisable to avoid spicy and irritating foods.

If astigmatism occurs, it is important to visit a hospital for an optometric examination promptly. If there is significant astigmatism, it should be corrected with glasses based on a medical optometric examination, as uncorrected astigmatism can lead to severe eye strain over time.

Will astigmatism cause the pupils to enlarge?

Astigmatism of the eye is a type of refractive error caused by an uneven curvature of the cornea's surface, resulting in different refractive powers along different axes. Once astigmatism occurs, particularly with a high degree of astigmatism, there can be a noticeable decrease in vision, distortion in sight, or in severe cases, significant eye fatigue. However, it generally does not lead to pupil dilation. Pupil dilation is caused by the paralysis of the ciliary muscle due to internal and external factors, resulting in enlarged pupils. Therefore, if symptoms of astigmatism appear, it is advisable to visit a hospital promptly for accurate diagnosis and appropriate treatment.

Can astigmatism wear orthokeratology lenses?

Astigmatism below 300 degrees generally can be corrected with orthokeratology (OK) lenses. Astigmatism is a type of refractive error where the eye has different refractive powers in different meridians, causing parallel light rays passing through the eye's refractive system to refract improperly and form two focal lines instead of a single focal point on the retina, resulting in a blurred image. Astigmatism can be categorized into regular astigmatism and irregular astigmatism. Regular astigmatism can be corrected using cylindrical lenses or glasses, while irregular astigmatism may require correction with corneal contact lenses, OK lenses, or surgical correction. Common symptoms of astigmatism include blurred vision, reduced visual acuity, and easy eye fatigue, and sometimes may also present with symptoms such as head tilting and headaches. Therefore, it is advisable to seek consultation in the ophthalmology refractive department if astigmatism symptoms appear.

Can high myopia with astigmatism be treated with surgery?

High myopia combined with astigmatism can also be treated surgically, but it requires the patient to be at least 18 years old, and both the myopia and astigmatism must have been stable for over a year without worsening. Before undergoing surgical treatment, a detailed eye examination is necessary. This includes an optometric examination to accurately measure the degree of myopia and astigmatism, a corneal topography test, and an ophthalmic ultrasound to understand the corneal curvature and thickness. Based on these parameters, a specific surgical plan is designed. If the patient’s corneal condition allows, laser surgery is the preferred method for correction. If the patient’s corneal condition is poor and not suitable for laser surgery, correction and treatment can be achieved through the implantation of a posterior chamber intraocular lens in phakic eyes.

What will happen if children's astigmatism is not treated?

If children with astigmatism do not receive treatment, the specific consequences will depend on the severity of the astigmatism. If a child has only mild astigmatism and does not exhibit any other clinical symptoms, treatment might not be necessary, and it will not impact the child's vision. However, if the astigmatism is severe, it is necessary to wear corrective lenses for astigmatism; otherwise, it may lead to a decrease in both far and near vision. This is especially true for compound and mixed astigmatism, which can cause a significant decline in a child's vision, and often results in visual fatigue. Children may exhibit symptoms such as eye pain, orbital pain, monocular diplopia, or tearing. Additionally, there may also be occurrences of compensatory head tilting and torticollis.

What should I do if I have astigmatism in my eyes?

Astigmatism should be corrected by wearing astigmatic lenses. Astigmatism is a type of refractive error where the refractive power of the eye varies along different axes, resulting in a refractive abnormality. Particularly with high degrees of astigmatism, there may be symptoms such as blurred vision, distorted vision, or even eye fatigue. Therefore, once astigmatism is detected, it is important to visit a hospital for a medical eye examination promptly. It is recommended that astigmatism of 50 to 75 degrees or more should be timely corrected with glasses, otherwise prolonged uncorrected astigmatism can lead to severe eye fatigue. Additionally, if adult patients have other refractive errors such as myopia along with astigmatism, they could also consider undergoing laser surgery for myopia correction.
