Astigmatism is a common eye condition in which the cornea (the clear front cover of the eye) is misshapen and unable to focus light properly on the retina. A normal, healthy cornea is round and symmetrical, shaped like a basketball; with astigmatism, the cornea resembles a football shape. This causes blurred or distorted vision, as well as eyestrain, headaches and squinting.
As a full-service ophthalmology practice, San Diego Eye Care Center works with many patients who suffer compromised vision due to astigmatism. We can diagnose and treat this eye condition, thereby restoring clear vision and improving quality of life.
More about Astigmatism
There are several causes of astigmatism. Many cases are hereditary and present at birth. Other people develop astigmatism after an eye injury (that scars the cornea) or eye surgery. A small portion of astigmatism cases are the result of another eye condition known as keratoconus, in which the cornea thins and takes on a cone-shape.
Some cases of astigmatism are caused by an irregular curvature of the eye’s lens; these cases are known as “lenticular astigmatism.”
Astigmatism is diagnosed during an eye exam. A series of tests is administered to measure how the eyes focus light.
Individuals with compromised vision due to astigmatism have a few different correction options. First, our optometrists can dispense a prescription for eyeglasses or contact lenses to compensate and correct the astigmatism. In our optical shop we offer a variety of attractive frames, which come in different colors, shapes and sizes to reflect your personal style.
If you prefer contact lenses, be aware that standard soft contact lenses won’t suffice (they conform to the shape of the eye). Instead, you will need either toric or gas permeable lenses. Toric lenses are specially designed soft contact lenses that have specific powers in specific areas of the lens to compensate for a patient’s visual deficiencies.
Gas permeable contact lenses, on the other hand, are rigid lenses with a uniform front surface that optically “replace” the misshapen cornea in order to properly reflect light. They maintain their spherical shape on the eye instead of molding to the irregular shape of the cornea like soft lenses do.
Another treatment option for many types of astigmatism is laser vision correction with LASIK. The procedure carefully reshapes the cornea so it can properly focus light on the retina. This is accomplished with the use of an advanced laser. LASIK is a short, practically painless procedure that delivers incredible results with little downtime. If you have astigmatism, the team at San Diego Eye Care Center can evaluate you as a potential LASIK candidate.
