Astigmatism is a common refractive error that affects how light enters the eye, leading to blurred or distorted vision. At VisionMD Eye Doctors, we help patients understand astigmatism and explore effective treatment options for clearer, more comfortable vision.
What is Astigmatism?
Astigmatism occurs when the cornea or lens has an irregular shape, preventing light from focusing properly on the retina. This results in blurry vision at all distances.
Common Symptoms of Astigmatism
- Blurred or distorted vision
- Eyestrain or discomfort
- Headaches
- Difficulty seeing at night
- Frequent squinting
What Causes Astigmatism?
Astigmatism can be present at birth or develop over time. Common causes include:
- Genetics: A family history of astigmatism increases risk.
- Eye Injuries or Surgery: Damage to the cornea may lead to irregular curvature.
- Keratoconus: A condition where the cornea thins and bulges outward.
Diagnosis and Treatment Options
1. Comprehensive Eye Exam
A thorough eye exam at VisionMD Eye Doctors can accurately diagnose astigmatism using specialized tests, such as corneal topography and refraction assessment.
2. Corrective Lenses
- Glasses: Prescription lenses help correct vision by compensating for corneal irregularities.
- Contact Lenses: Toric lenses are designed specifically for astigmatism correction.
3. Laser Eye Surgery
For those seeking a permanent solution, LASIK or PRK surgery reshapes the cornea to improve vision.
4. Orthokeratology (Ortho-K)
Specialized rigid contact lenses worn overnight can temporarily reshape the cornea for clear daytime vision.
