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.
