Astigmatism Explained in Detail

There are a number of causes to blurry or unfocused vision. From cataracts to an irregularly shaped eyeball, our eyes are subject to a great number of deformities and defects that may render our seeing less than effective when we need it. Amongst some of the most common causes for bad vision, one that is almost entirely predictable for many adults is astigmatism. So what is astigmatism and how can it be cured? Thanks to the breakthroughs in technological advancements and the care of dedicated doctors and their teams, LASIK surgery professionals can correct astigmatisms in adults; thus making what many in the past thought impossible a startling reality. (Literally) Here’s what astigmatism is and the cure found in LASIK solutions.

What Is Astigmatism?

Astigmatism is an optical system that allows the right rays to come into the eye at two or more perpendicular planes. Because the refraction of light is the only way any of us can see clearly, this added light ray confuses the eye in a way and puts the focus on more than one point, causing blurriness when one attempts to focus on one object. Astigmatism can affect far sight, near sight, or both.

Different Forms of Astigmatism

There are two distinct types of astigmatism. The first type affects the focus of objects away from the eye’s optical axis, the central ray of light coming into the eye. This form of astigmatism can occur when a light ray is running perfectly straight through the eye. Once the second ray of light is present in the delicate balance of light and dark that is needed for us to see our world, the vision becomes blurred and without depth or clear perception.

The second form of astigmatism is when the optical system itself is not conformed to the optical axis; which also creates disharmony between two light-entry points.

Both of these types of astigmatism come through a flap of tissue called the Cornea at the front of one’s eye. This flap of tissue is the object of a LASIK procedure. During surgery, the cornea is adjusted in such a way so as to eliminate any secondary admittance of light into the retina, allowing the patient to see just one focus point instead of several.

What A Surgical Procedure Entails

Because all light rays must pass through the cornea, the cornea is the main focus during a surgical procedure to correct astigmatism. The surgeon takes the cornea flap and places it on the eye in the manner that allows the patient to see clearly. LASIK surgery then is used to set the newly placed cornea into its new place, and the patient then can see as well as anyone else. All of this and more are available at Tylock LASIK. We strive to make a better vision a reality for everyone, and thanks to the advancements of our day and age, astigmatisms no longer have to go uncorrected.
