I have red lines above cornea for both eyes from past 6 months with irritation and eyes blinks continusloy with some discharge. Consultetd doctor in nethradhama not cured yet. Doctor said its due to dust and watiching screen. So gave eyemist drops and gel to put for 3-4 months and has asked to avoid dust and used anti glare lens. Did that but still didnt work. Pls suggest.
People may have weak eyes due to a variety of reasons. Astigmatism happens to be one of those reasons. When one is affected by astigmatism, it results in blurry vision. The eye has a part called the cornea, which is the outermost layer of the eye and is responsible for allowing light to enter. When the cornea is not shaped as it should be, it leads to astigmatism.
However, this is not the only condition under which it can occur. In fact, there are two different types of astigmatism. One is corneal astigmatism which is the result of an odd-shaped cornea. The other is lenticular astigmatism, which occurs when the lens has an incorrect shape. More often than not, people are born with astigmatism. However, there are chances of developing this eye disorder after an eye injury or after an eye disease.
How to diagnose?
There are a few ways in which astigmatism can be diagnosed.
- One of the most popular methods is the visual acuity test. This measures the distance at which a letter is read clearly, as compared to what it should be.
- Another way is by refraction. By placing lenses in front of the eyes, the way they focus light is measured.
- The third way by which astigmatism can be detected is by keratometry, also known as topography. Light is focused on the cornea and the reflection is measured to find the curvature of that area.
The easiest way to go about treating astigmatism is by using corrective lenses. This is usually the method of treatment for people whose astigmatism is not that bad. The lenses could either be a part of spectacles or used as contact lenses. The good part about contact lenses is that the field of view is wider.
Orthokeratology (Ortho-k) works to improve astigmatism by using lenses as well. However, the lenses are of the hard variety. These lenses are useful for corneal astigmatism patients as they reshape the eye. Usually, they are worn while sleeping and most people can have normal vision the next day. However, if one stops using them, the eye goes back to its original state. So, they are not a permanent solution.
Surgery, however, can be a permanent solution to astigmatism. LASIK and PRK are two of the most popular types. RK is also popular, but to a lesser extent. It is good to remember that the risks of surgery should be discussed with a doctor prior to undergoing one.
