What should I do about hyperopic astigmatism?

In general, hyperopic astigmatism may be caused by genetic factors, poor eye-use habits, abnormal corneal development, abnormal eyelid pressure, lens dislocation, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition under a doctor's guidance through non-surgical management, medication, or surgical treatment. Specific analyses are as follows:

1. Genetic factors: If one or both parents have hyperopic astigmatism, their children have a higher probability of inheriting it, often due to congenital abnormalities in the shape of the cornea or lens. Regular refraction exams at a professional ophthalmology clinic are recommended. Corrective eyeglasses should be worn according to the degree of refractive error. For adolescents, orthokeratology lenses may be considered to control myopia progression.

2. Poor eye-use habits: Prolonged close-up reading or writing, or tilting the head while viewing objects, can disrupt the eye’s accommodation function and worsen symptoms of hyperopic astigmatism. Maintain proper reading and writing posture, keep eyes 30–40 cm from books, look into the distance for 5 minutes every 30 minutes of near work, and avoid using eyes in dim lighting.

3. Abnormal corneal development: Irregular curvature during corneal development causes disordered light refraction, leading to hyperopic astigmatism. In addition to wearing corrective glasses, adults may consider undergoing femtosecond laser surgery after medical evaluation, which precisely reshapes the cornea to correct refractive errors.

4. Abnormal eyelid pressure: Eyelid inflammation or trichiasis (inward-growing eyelashes) can chronically press on the cornea, altering its shape and inducing hyperopic astigmatism. Follow medical advice to use medications such as tobramycin dexamethasone eye ointment, levofloxacin eye drops, or erythromycin eye ointment to treat inflammation. For severe trichiasis, eyelid entropion correction surgery may be performed to relieve corneal pressure.

5. Lens dislocation: Trauma or congenital conditions may cause abnormal lens positioning, changing refractive power and resulting in hyperopic astigmatism, often accompanied by significant vision loss. Prompt medical care is required, including lens repositioning surgery or intraocular lens implantation to restore normal refractive function.

Routine eye protection is important—avoid eye injuries. Diet should include foods rich in vitamin A and lutein, such as carrots and blueberries. Ensure adequate sleep, reduce eye fatigue, and have regular eye examinations to monitor changes in vision.
