How LASIK eye surgery corrects astigmatism

An imperfection involving the curvature of the patient’s lens or cornea can cause an eye condition known as astigmatism. For normal eyes, the lens and cornea are smooth and tend to curve equally in all possible directions.

As a result, light rays can focus strongly on the retina. Light entering the eye cannot be refracted properly if the lens and cornea are not evenly curved and smooth.

The result is a refractive error. Lenticular and corneal astigmatism will cause distorted and blurred vision when looking at distant and near objects.

Astigmatism is quite common, but doctors don’t know why the shape of the cornea or lens differs so much from person to person. However, there may be a link between astigmatism and hereditary factors.

You may have astigmatism if you suffer from frequent headaches, eye strain, discomfort, distorted or blurred vision, or if you need to squint to see things. Lasik is a form of eye surgery that corrects refractive errors. It can be used to treat astigmatism so that the patient no longer needs to wear glasses or contact lenses.

Role of Lasik eye surgery in correcting astigmatism

A tiny amount of corneal tissue is extracted so that the surgeon can correct the asymmetrical curvature of the patient’s cornea. The result is that the eye becomes rounder instead of oval.

The light can focus on a singular point on the patient’s retina, allowing them to see more clearly. If you currently have astigmatism and are tired of wearing contact lenses or glasses, Lasik can serve as a permanent cure for your astigmatism.

The role of Lasik eye surgery is to reshape the eyes to help them focus on the items more clearly and sharply. It is a corrective refractive procedure that usually produces lifelong results.

Lasik goes serve as a permanent solution your astigmatism or other vision problems. Only a small number of patients will need a second procedure in the future. You will be no need to wear contact lenses anymore in many cases.

Contact lenses can make eyes dry, itchy, red and irritated. They can also get dirty and require frequent cleaning and replacement. Lasik is also a profitable procedure.

People who wear glasses or contact lenses should replace their corrective lenses every 2 to 3 years. $500 can easily add up to tens of thousands of dollars over a person’s lifetime.

Although Lasik may have a higher initial cost, it will quickly pay for itself within a few years. If you are interested in clearer and better vision, then Lasik may be for you. Another advantage of Lasik is that the the results are almost immediate.

It is important to sleep 8 hours after the procedure. Rest is essential. Avoid screens during recovery. You don’t want to exacerbate eye strain, so avoid texting or playing video games for a few days.

Your eyes should also be cool and hydrated to avoid dry eyes. Use the eye drops that your eye surgeon has prescribed for you. Any cosmetics, such as eyeliner or other makeup products, should also be avoided for at least seven days after Lasik.

Extreme weather conditions should also be avoided during your recovery. Extreme cold and hot temperatures should be avoided. Wear sunglasses if you have to go out on a sunny day.

Final Thoughts

If you’re dealing with astigmatism, your eyes will be dealing with a curve resembling the shape of a soccer ball. When the curvature is longer in a section, you will have difficulty seeing objects near or far from you.

Lasik is designed to smooth out the abnormal curvature so that the corneas look more evenly round.
