Astigmatism is a common refractive error that affects the shape of the eye’s cornea or lens, leading to blurred or distorted vision. It is estimated that around one in three people have some degree of astigmatism, making it a prevalent vision condition.
What is Astigmatism?
Astigmatism occurs when the cornea or lens of the eye has an irregular shape. In a healthy eye, the cornea and lens are smooth and evenly curved, allowing light to focus properly on the retina. However, in individuals with astigmatism, the cornea or lens is irregularly curved, causing the light to refract unevenly and resulting in blurry or distorted vision at various distances. Astigmatism can be classified as either corneal or lenticular, depending on whether the cornea or lens is primarily responsible for the irregularity.
Signs and Symptoms of Astigmatism
The most common symptom of astigmatism is blurry vision, both up close and at a distance. Other signs may include eye strain, headaches, squinting, and difficulty with night vision. Astigmatism can also cause objects and lines to appear distorted or wavy. If you are experiencing these symptoms, it is important to visit an eye care professional for a comprehensive eye exam to determine the presence and severity of astigmatism.
Causes and Risk Factors of Astigmatism
Astigmatism can have various causes and risk factors. In some cases, individuals may be born with astigmatism, as it can be a result of genetic factors. It can also develop after an eye injury, or as a complication following eye surgery. Certain eye conditions, such as keratoconus, can also contribute to astigmatism. It is important to note that astigmatism can occur alongside other refractive errors, such as shortsight (myopia) or longsight (hyperopia).
Diagnosis and Treatment for Astigmatism
The diagnosis of astigmatism involves a comprehensive eye examination, including a visual acuity test, refraction assessment, and measurement of corneal curvature. Once astigmatism is confirmed, the appropriate treatment options can be explored.
During the procedure, a precise laser is used to reshape the cornea, correcting the irregular curvature that causes astigmatism. By creating a more symmetrical corneal shape, the laser surgery aims to improve the refraction of light onto the retina, thereby addressing the blur and distortion associated with astigmatism. With advancements in technology and surgical techniques, laser eye surgery for astigmatism has become a popular choice for individuals seeking long-term freedom from glasses or contact lenses.
