Understanding Astigmatism
Astigmatism is a common vision condition caused by an irregular curvature of the cornea, leading to blurred or distorted vision at all distances. It often occurs alongside nearsightedness (myopia) or farsightedness (hyperopia) and can affect people of all ages.
A slight degree of astigmatism (up to 0.5 diopters) is considered normal in the human eye. While it is usually present from birth, in some cases, it can develop over time due to natural changes in the eye.
What Causes Astigmatism?
Astigmatism develops when the cornea or lens of the eye has an irregular shape, preventing light from focusing properly on the retina and causing blurred vision.
Normal Eye

Clear vision depends on light focusing precisely on the retina at the back of the eye. In a healthy eye, the cornea and lens bend (or refract) light so it lands perfectly on the macula—the point of sharpest vision. This process, known as refraction, is measured in diopters (D). When refraction is at zero diopters, objects appear crisp and in focus.
Eye With Astigmatism

Astigmatism occurs when the cornea is irregular, more like an egg, causing light to focus at multiple points instead of a single sharp point on the retina. This distortion results in blurred or stretched vision, where dots may appear as lines. To correct this, lenses or surgery adjust the refractive power, aligning light properly onto the retina—similar to how toric lenses work.
Who Is Astigmatism Treatment For?
Astigmatism can affect people of all ages, from children to older adults.
Many people are born with it, while others develop Astigmatism over time due to eye changes, injury, or conditions like keratoconus.
Astigmatism often occurs alongside nearsightedness or farsightedness. While mild cases are common, higher degrees of astigmatism may require glasses, contact lenses, or vision correction surgery for clear and comfortable vision.
How Can Astigmatism Be Treated?
Astigmatism can be corrected with glasses, contact lenses, or surgery, depending on its severity and type. While mild cases are easily managed with eyewear, irregular astigmatism—caused by an uneven corneal shape—often requires advanced treatments beyond standard glasses.
At the Fadi Kherdaji Eye Clinic, we offer state-of-the-art laser procedures and premium lens treatments to correct astigmatism, whether it occurs alone or alongside nearsightedness or farsightedness.
To determine the best treatment, we conduct a comprehensive consultation and in-depth diagnostic assessment, ensuring safety and precision before any procedure.
