Irregular Astigmatism, Right Eye (ICD Code: H52.211)
Name of the Condition
- Common Name: Irregular Astigmatism
- Medical Term: Irregular Corneal Astigmatism
Summary
Irregular astigmatism is a vision condition characterized by an uneven curvature of the cornea, leading to distorted or blurred vision in the right eye. Unlike regular astigmatism, the irregular shape cannot be corrected simply by glasses or soft contact lenses.
Causes
The primary causes of irregular astigmatism include:
- Eye injuries or trauma
- Certain eye surgeries
- Keratoconus or other corneal diseases
- Scarring of the cornea
Risk Factors
- History of eye surgeries like LASIK
- Eye injuries or infections
- Genetic predispositions to corneal disorders
Symptoms
- Blurred or distorted vision
- Eye strain or discomfort
- Difficulty seeing at night
- Frequent headaches related to eye strain
Diagnosis
- Comprehensive eye examination
- Keratometry to measure corneal curvature
- Corneal topography to map the cornea's surface
Treatment Options
- Rigid gas-permeable (RGP) contact lenses: Help in reshaping the cornea to correct vision.
- Corneal cross-linking: Strengthens corneal tissue in cases related to keratoconus.
Surgery: Options like corneal transplants in severe cases.
Prognosis and Follow-Up
With appropriate treatment, most patients can manage symptoms effectively. Regular follow-ups ensure monitoring of the condition and timely adjustments to treatment plans.
Complications
If not properly managed, irregular astigmatism can lead to permanent vision loss or significant difficulties with everyday tasks requiring clear vision.
Lifestyle & Prevention
- Avoiding eye trauma and protecting eyes during activities
- Regular eye checkups for early detection and management
- Managing and monitoring other eye conditions like keratoconus
When to Seek Professional Help
- Sudden changes in vision
- Persistent eye discomfort or pain
- Difficulty with vision correction using current methods

Tips for Medical Coders
- Ensure specificity by noting the distinction of the right eye in the diagnosis.
- Double-check for any associated conditions like keratoconus that might require additional codes.
- Avoid using general astigmatism codes (H52.20) when the condition is specifically irregular in nature.
