An excimer laser is like a magical light that can help fix things in your eyes. It uses a special gas called a noble gas, like xenon or argon, and combines it with another gas, like fluorine, to create a powerful beam of light. This beam of light is super duper precise, and can help fix problems with your eyes like nearsightedness, farsightedness, and astigmatism.
Here’s how it works: Imagine your eye is like a camera that can’t focus properly, so everything looks blurry. The excimer laser beam gently reshapes the surface of your eye, almost like sculpting or molding Play-Doh, until your eye can see things more clearly.
Don’t worry, though – it doesn’t hurt at all! The laser only touches the surface of your eye, and it will only work for a few seconds at a time. You might feel a little bit of pressure or a bright light, but that’s about it. Afterwards, you’ll be able to see things more clearly than ever before, without needing glasses or contacts. Cool, huh?
