Astigmatism is one of the most common vision related problems that affects more than half of the human population to some extent. Despite the fact that it is so common, people often tend to misunderstand it. In fact, even medical students find it hard to come up with right answers. Some confuse it with strabismus, a condition which causes abnormal alignment of eyes. And then there are others who do not know that it can be treated with iLASIK laser treatment. What that basically means is that there is quite a bit of confusion surrounding this optical defect.
So let us first try to figure out what is astigmatism all about.
Astigmatism is a condition that is caused due to imperfection in the curvature of cornea. People suffering from this problem have differently curved corneas. However, the difference is very subtle. This irregularity in the curvature of cornea leads to blurry vision where the patient finds it hard to see fine details of objects clearly. It can also cause frequent headaches after long hours of reading or other visual tasks. Squinting is also common as people try extra hard to focus on objects placed at a distance.
Astigmatism can be either regular or irregular. Regular astigmatism is a condition where principal medians of eyes are perpendicular to each other. Irregular astigmatism, on the other hand, is a condition usually caused by keratoconus, a disease that leads to gradual thinning of cornea. While regular astigmatism can be corrected with the help of eye glasses or laser surgery, severe cases of irregular astigmatism might require custom contacts for best results.
However, there are a lot of people who wonder whether laser surgery for the eye can actually treat astigmatism. The answer is yes in most cases. And the best part is that the results of the LASIK surgery are permanent. LASIK stands for Laser-assisted in Situ Keratomileusis. The surgery involves reshaping of the inner layer of the cornea to treat the condition.
However, only an eye specialist can determine whether you are a good candidate for this type of treatment or not. Also, it is important to determine the type of astigmatism you are suffering from before choosing the best treatment for you.
People who want to free themselves from their dependency on glasses and contact lenses once and forever can also opt for laser treatment for eye. So even if you are suffering from some other optical errors such as myopia or long sightedness, LASIK can help you restore normal vision.
