?What are the main differences between regular and irregular astigmatism

Regular astigmatism occurs when the cornea or lens has a uniform curvature in one principal meridian, leading to consistent vision distortion. Irregular astigmatism, however, results from an irregular corneal shape or lens surface, causing unpredictable and often severe vision abnormalities.

?How is astigmatism diagnosed, and what factors influence its treatment approach

Astigmatism is typically diagnosed through a comprehensive eye examination, including visual acuity tests and refraction assessments. The treatment approach depends on factors such as the severity of astigmatism, the presence of other refractive errors, corneal irregularities, and the patient's lifestyle preferences. Options may include corrective lenses (glasses or contact lenses) or surgical interventions like LASIK or PRK.
