Considering how life-changing LASIK is, it can be easy to think it must be complicated and risky! While it’s true that there are risks with LASIK, it’s a straightforward procedure. Keep reading to learn the basics about how LASIK corrects your vision!
The science behind LASIK has to do with refraction. Sight is created when light goes through the cornea and focuses in the lens of the eye.
Once light has passed through the cornea and lens, it goes to the retina. The retina translates the light as an electrical impulse to the brain, where it becomes an image.
Although the lens is an important part of the eye, it is not responsible for focusing. Instead, this is controlled by the cornea. Refractive errors like nearsightedness and farsightedness occur because of a misshapen cornea.
A steep cornea will make an eye nearsighted while a flatter cornea will have the opposite effect. Astigmatism occurs with a misshapen cornea that has many places to focus light.
During LASIK, the shape of the cornea becomes permanently corrected. At Global Laser Vision in San Diego, we use wavefront technology.
Wavefront technology scans the surface of the eye, eliminating chances of human error! With wavefront technology, we are able to create a map of your unique eye to follow during LASIK.
Before LASIK you will need to make sure you have a ride planned out. You should avoid wearing makeup and facial lotions on the day of LASIK. Having a clean face is essential during LASIK, since makeup could cause an infection.
If you wear contacts you will need to stop wearing them 2 weeks before the surgery. Wearing contacts can actually change the shape of your cornea, at least temporarily. Wearing contacts before LASIK could affect the accuracy of the measurements.
The surgery itself usually takes less than 30 minutes to complete on both eyes. Your eyes will be numbed with eye drops so you don’t have to worry about pain!
After LASIK, you will need to rest in the clinic for a few minutes. Many patients experience vision improvement immediately after LASIK. Don’t worry if it takes you longer, because it’s normal!
Your vision may feel hazy or smoky, which goes away in a few days. You’ll want to have sunglasses when going outside, since your eyes will be sensitive to light and the sun.
It will take several months before you are completely recovered. The first few days after LASIK are likely to be the worst ones. You’ll want to avoid screens and give your eyes ample time to rest.
After the first few days, you’ll be able to integrate more of your normal routine into your daily life. Your LASIK surgeon will be able to tell you when you can expect to return to all activities.
You’ll need to see your eye doctor periodically for follow-up appointments. Your eye doctor will check your vision, as well as checking for complications.
