A Complete Guide to Astigmatism (cylinder): Understanding Eye Shape Irregularities

Astigmatism, or cylindrical refractive error, is a common refractive error that affects how light enters the eye, resulting in blurred vision. Unlike a perfectly spherical cornea, an astigmatic cornea has an irregular shape, similar to a rugby ball. This irregularity causes light to focus at multiple points within the eye, leading to distorted and blurred vision at both near and far distances.

Causes of Astigmatism

It can also be caused by external factors, such as eye injuries, corneal scars, or eyelid conditions. An irregular curvature of the cornea can lead to astigmatism, resulting in a distorted image on the retina.

Symptoms of Astigmatism

People with astigmatism often experience blurry vision, distorted images, and eye strain. Headaches and eye irritation are also common complaints. Individuals with astigmatism may find it difficult to see sharp outlines or small details. It’s important to note that astigmatism often occurs alongside nearsightedness (myopia) or farsightedness (hyperopia).

Diagnosis of Astigmatism

Treatment Options for Astigmatism

Fortunately, there are effective treatment options available to correct the visual effects of astigmatism. A common solution is wearing glasses or contact lenses with a cylindrical correction. These correct the irregular shape of the cornea, focusing light at a single point.
For those considering a more permanent solution, laser eye surgery, such as LASIK (Laser-Assisted In Situ Keratomileusis), may be an option. This surgical procedure reshapes the cornea to correct refractive errors, enabling clear vision without the need for external corrective aids.
