If you have always wanted to get rid of your glasses and contacts, then you may have considered getting laser eye surgery. Laser eye surgery has a pretty good track record in helping people get rid of their glasses and contacts. Depending on the severity of your vision, your vision may not be completely corrected. However, laser eye surgery will make your vision better and it may allow you to switch to less strong prescription for your glasses. So, how does laser eye surgery work?
The lenses in your eyes do the majority of focusing on what you are seeing. The lenses are behind the pupil and iris in your eye. The pupil dilates and contracts to allow more or less light in, which hits the lens. The small muscles that surround the lens then move it around and help it flex and adjust shape so it can use that light and focus in on the objects that you are looking at. Ideally, the lenses of your eye are perfectly shaped so you can focus without problems. However, this isn't always the way that the real world works. For many people, the lens is misshapen or isn't working the way that it should. That's what causes things like nearsightedness, farsightedness, or a stigmatism.
Laser Eye Surgery
The way that the laser eye surgery works is that the doctor will use a laser and reshape the lens of your eye. That reshaping will cause your lens to get as close to perfect as possible. The laser slices minuscule pieces off the lens so that it is correctly shaped. Any other method of reshaping your lens would be highly invasive and could cause more problems because it could cause scarring on the lens. In contrast, the laser is so tightly focused and precise, and it makes such small adjustments that it shouldn't damage anything. Generally the procedure only takes a few minutes and you are able to go home. You should notice a change in your vision pretty quickly. Your may be dilated for the procedure, and since this can make your eyes blurry, you might not see a difference in your vision until after the dilation wears off.
If you are tired of wearing your glasses or contacts, laser eye surgery may be the right option for you. You should talk to your optometrist to see what works for you.
