Astigmatism

Astigmatism is a refractive error due to an irregularly curved cornea or lens (more curved in one meridian), causing blurred, distorted vision at all distances, often with headache/asthenopia. Treatment: cylindrical (toric) lenses in glasses or toric soft/rigid contact lenses; refractive surgery (LASIK/toric ICL) in adults; screen for keratoconus if progressive.

Common Symptoms

Blurred/distorted vision at all distances; eye strain/headaches; squinting; by cause (corneal/lenticular)

Causes and Pathogenesis

Irregular curvature focuses light at two focal points, causing distortion.

Treatment

Cylindrical/toric glasses/contacts; refractive surgery in adults; screen for keratoconus

Preventive Measures

Correct astigmatism; screen for keratoconus.
