Introduction
In general, astigmatism of 300 degrees is considered severe astigmatism. Astigmatism is a refractive error of the eye, usually related to the curvature of the cornea. It can be caused by abnormal congenital development, ocular trauma, corneal diseases, or other factors, and may lead to symptoms such as blurred vision, decreased visual acuity, visual fatigue, and neck tilting. Typically, astigmatism less than 100 degrees is classified as mild astigmatism.
In general, 300 degrees of astigmatism is considered severe astigmatism. The detailed analysis is as follows:
Astigmatism is a refractive error of the eye, usually related to corneal curvature. It may be caused by abnormal congenital development, eye trauma, corneal diseases, and other factors. Patients may experience symptoms such as blurred vision, decreased visual acuity, visual fatigue, and head tilting. Typically, astigmatism less than 100 degrees is classified as mild, 100–200 degrees as moderate, 200–300 degrees as severe, and over 300 degrees as high astigmatism. Therefore, 300-degree astigmatism falls into the category of severe astigmatism, which can lead to poor vision and blurred vision.
If severe astigmatism occurs, patients can seek treatment at a reputable hospital through surgical procedures such as laser surgery, limbal relaxing incisions, or implantable intraocular lens surgery.
