True or False: Irregular astigmatism can be caused by corneal dystrophy.

Irregular astigmatism can indeed be caused by corneal dystrophy. Corneal dystrophies are a group of genetic disorders that lead to changes in the structure and clarity of the cornea. These conditions can affect the curvature of the cornea, resulting in irregularities that lead to distorted vision, characteristic of irregular astigmatism. Unlike regular astigmatism, which can often be corrected with standard lenses, irregular astigmatism requires specialized contact lenses or other forms of treatment due to the unpredictable curvature of the cornea.

This recognition of the relationship between corneal dystrophy and irregular astigmatism highlights the importance of understanding corneal health and its impact on vision.
