Introduction
Astigmatism can be corrected with eyeglasses to restore visual acuity. Astigmatism results from an irregularly shaped cornea—specifically, an uneven corneal surface where the refractive power varies across different regions. Corrective eyeglasses are a primary method for managing astigmatism. For individuals with mild astigmatism, wearing glasses is the most effective and safest treatment option. However, some patients may experience discomfort or intolerance to astigmatic correction, particularly when the prescribed lens power is relatively high.
Daily eye-use habits are often particularly poor. For example, frequently lying—either to others or while reading in bed—prolonged mobile phone use, and extended periods of work or gaming on a computer may contribute to the development of astigmatism. Common accompanying symptoms include reduced visual acuity, photophobia (light sensitivity), and excessive tearing. So, how can vision be restored in individuals with astigmatism?
How to Restore Vision in Astigmatism
Corrective eyeglasses are the primary method for restoring vision in astigmatism. Astigmatism arises from an irregularly shaped cornea—specifically, an uneven corneal surface where refractive power varies across different regions. Vision correction can be achieved primarily through wearing glasses. For individuals with mild astigmatism, glasses represent the most effective and safest treatment option. Second, some patients may find astigmatic glasses uncomfortable or intolerable; for such cases, refractive surgery at a hospital may be considered.
Refractive surgery not only corrects myopia but also effectively treats astigmatism. Alternatively, specially designed toric soft contact lenses can also correct astigmatism. Surgical intervention is appropriate for adults with stable astigmatism who are either unsuitable for or unwilling to wear corrective lenses; in such cases, surgery enables relatively rapid visual recovery.
Currently available surgical options include femtosecond laser surgery, keratotomy, excimer laser refractive corneal surgery, and corneal transplantation. Generally, successful surgery restores vision to normal levels. We hope this information proves helpful to you.
