Web among them, irregular astigmatism is defined as astigmatism that cannot be corrected with spherocylindrical spectacle lenses, and thus is one of the important causes of suboptimal visual function, such as corrected visual acuity and contrast sensitivity, in otherwise healthy eyes 1, 2. It’s a type of refractive error that causes blurred vision at all distances.
Wang Makes A Compelling Case For The Importance Of This Topic.
Web irregular astigmatism is usually the result of an injury or infection or a condition like keratoconus where the pattern of curvature is irregular and asymmetric. This is due to the gradual thinning or distortion of the cornea and can occur after injury to the eye or as a result of a degenerating eye disease, such as keratoconus. This type of astigmatism is harder to correct than regular astigmatism. It may be the result of an eye injury and related damage to the cornea, or a condition such as keratoconus.

This type of astigmatism can be caused by various factors, including eye injuries or surgery, keratoconus, scarring of the cornea, or certain types of contact lenses. Web irregular astigmatism is normally the result of injury or keratoconus and occurs when the cornea is pulled into a distorted shape, due to scarring or the progression of a cone in keratoconus.
