How LASIK Surgery Works

Like much of the technology that surrounds our everyday lives, it can be easy to take things for granted. For example, we use mobile devices, computers, and even cars every single day without stopping to consider how they operate.

The same is true of LASIK surgery. How, after all, can shooting a laser into someone’s eye actually fix their poor vision?

For those considering LASIK surgery, this question becomes much more real, and it can help to understand a bit about the procedure and how it works.

We’re here to explain!

Why So Many People Have Poor Vision in the First Place

To understand how LASIK work, it’s best to understand why someone might end up needing the procedure in the first place.

The eye is an incredibly complex part of human anatomy. For one to have clear vision, all of the different parts of the eye need to line  up just right, much like focusing a camera lens.

The two most important parts as it relates to clear vision are the cornea and the lens. The lens is inside your eye, and the cornea is the thin layer of tissue that covers the outside of your eye. When these two parts aren’t aligned – if, for example, the eye is too long or the cornea isn’t rounded enough – then you end up with poor vision.

This is called a refractive error because the misalignment causes light to spread out over your retina, instead of being focused.

How LASIK Fixes the Problem

When you have LASIK surgery, the surgeon cuts a very thin flap on your eye, exposing the corneal tissue behind it. The cornea is what the surgeon reshapes with the laser, called an excimer laser, which shoots out cool, ultraviolet rays.

After the cornea is properly reshaped – which usually only takes a couple of minutes to complete – the flap is replaced and reattaches itself to the eye.

The lens and the cornea are now on the same page, giving you much clearer vision as quickly as the next day.

Much like the eye, the technology that is used for performing LASIK is incredibly precise and advanced, which actually gives surgeons a tremendous amount of control over the operation.

These surgeons, of course, are incredibly experienced and educated. To become a LASIK surgeon, one must become an MD, which takes a total of nine years in college, which includes the required internship at a hospital. Then, an aspiring LASIK surgeon must complete a three- or four-year residency in ophthalmology. In other words, provided you find a qualified and certified LASIK surgeon, your chance of success with LASIK is very high.  

In fact, 96% of patients end up with 20/20 vision or better. LASIK is incredibly safe, and it is rare for any complications to develop.
