Thousands of people from around the globe have benefited from LASIK.
While this fact remains, there are still questions from the general public regarding its effectiveness with astigmatism and nearsightedness.
While these two vision problems can be related, they are often two separate issues.
Yes LASIK works for nearsightedness and astigmatism, but not in all cases.
It’s important to know what is causing your nearsightedness in the first place. It is equally important to know what type of astigmatism you have.
What Astigmatism Is
In general terms, astigmatism is an elongation of the cornea. A normal and healthy cornea is round where a cornea with astigmatism is more oval in nature. This causes irregularity in vision which usually equates to nearsightedness.
Different Types of Astigmatism
If you have “regular astigmatism,” which is found in most cases, then LASIK can correct your vision. The way that the procedure works is actually quite simple. By using lasers, an ophthalmologist is able to cut away layers of the cornea to make it as round as a normal healthy one would be. This corrects the way that light enters through the eye and you can see as normal as a person with 20/20 vision.
If you have “irregular astigmatism,” which is less common, LASIK becomes a little bit tricky. Irregular astigmatism can be caused by previous surgeries, injuries, or eye disease (the most common being keratoconus). In these cases, custom contact lenses can be worn. Laser-assisted in situ keratomileusis (LASIK) is not out of the question, but you will only know if it is right for you by getting an initial screening by an ophthalmologist.
LASIK Works for Astigmatism in Most Cases
If you have regular astigmatism, which is causing nearsightedness, then LASIK can help. In many cases, people with astigmatism have been able to get their vision corrected to a level close or equal to 20/20. In some cases where the cornea is severely misshaped, LASIK will only help to get your vision closer to normal, but you most likely won’t be able to have PERFECT vision.
LASIK eye surgery has proven an effective treatment for people with mild or moderate astigmatism. LASIK is also a convenient option for physically active people who find eye glasses or contacts a nuisance, even if they don’t have astigmatism.
What Nearsightedness (Myopia) Is
Generally speaking, nearsightedness is caused by an elongation of the cornea (also known as astigmatism). However, there are several other factors that can cause myopia.
Causes of Nearsightedness
One of the main causes of nearsightedness is due to an increased size of the pupil itself during night or other low-light environments. This allows more unfocused light to enter the eye, causing vision problems.
Another cause of nearsightedness is strain on the eye. When people engage in activities where computer screens or other electronic devices are used close to their face for extended periods of time, it overworks the focusing mechanism of the eye. When this person stops engaging in that particular activity, the eye is unable to refocus at “new” distances. Repetitive strain can cause long term nearsightedness.
Myopia can also be caused by irregular levels of blood sugar and can even be a warning sign of a developing cataract. Seeing an eye doctor regularly can help diagnose this type of nearsightedness.
