H52.2
Astigmatism
Clinical Classification Guidelines
Medical Intelligence & Overview
Astigmatism is a common eye condition that affects the way light enters the eye, leading to blurred or distorted vision. It occurs when the cornea or the lens of the eye has an irregular shape rather than the typical smooth, round form. This irregular curvature causes images to focus unevenly on the retina, resulting in visual impairment. While it can affect individuals of all ages, it is particularly prevalent among children and adults who experience ongoing vision issues.
Causes & Symptoms
Clinical Causes: Irregular shape of the cornea or lens, often congenital (present at birth) Genetic factors passed down from family members Eye injuries or surgeries that alter the corneal surface Keratoconus, a condition where the cornea thins and bulges outward Certain diseases and conditions that affect eye shape
Key Symptoms: Blurred or distorted vision at all distances Difficulty seeing clearly in low light conditions Eye strain and discomfort after visual tasks Headaches, especially after reading or focusing Squinting to improve vision Seeing halos or glare around lights
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination performed by an optometrist or ophthalmologist. The eye care professional will perform tests such as refraction assessments and keratometry to measure how light is focused by the eye and to determine the degree and type of astigmatism. A detailed eye exam helps assess the shape of the cornea and decide the appropriate corrective measures.
Treatment Protocols: Eyeglasses with cylindrical lenses designed to counteract the irregular shape of the cornea Contact lenses, including toric lenses specifically designed for astigmatism Refractive surgery options like LASIK or PRK to reshape the cornea Orthokeratology (Ortho-K), which uses specially designed contact lenses worn overnight to temporarily reshape the cornea
