There are tiny nerves all throughout the cornea that take care of this role.ĭuring lasik, a lasik flap is created and a laser is used to remodel the cornea. ![]() Typically, when our eye notices that it is drying out, it sends a signal to produce more tears. After lasik, our eye has a reduced ability to produce natural tears. Lasik will cause a short-term dryness for everyone. This is commonly described as Computer Vision Syndrome. The tear film dries out more and there is more fluctuation of vision. This lack of blinking will cause your eye to dry out. We are just too much "in the zone" to worry about blinking. This is the case with any task that requires cognitive demand. W hen we are working on the computer, we don't blink as frequently as normal. Some days you may notice that your vision is a little bit more blurry than other days. This fluctuation of vision can be more or less be present all the time, especially if you had preexisting dry eye prior to lasik, or it can come and go without any good reason. Immediately after blinking things are fine (since the eyelids smooth the tear film out), but a few seconds later the tear film breaks down, dries out and becomes irregular - vision becomes blurry. When the tear film becomes irregular, it scatters more light and makes our vision more blurry. Instead of staying nice and smooth and uniform, the tear film can break down and become irregular in between our blinking. In dry eye, the tear film can become unhealthy and unstable. Vision must pass through this tear film before it reaches the cornea and the rest of the eye. The smoother and more uniform everything is (by having a healthy tear film), the better vision we get. Every blink of our eyelids works sorta like a squeegee to maintain the smoothness and uniformity of the tear film. This tear film has different layers including a watery layer (which is what we think of when we think of tears) and a protective oil layer on the surface of the eye to keep everything in place and prevent evaporation. On the surface of the eye is a protective liquid coating called the tear film. Here is what is happening: It's all about the tear film What you may notice is that immediately after blinking, the vision improves for a second or two but then rapidly becomes blurry again. One symptom of dry eye can be fluctuation of vision. But dry eye can cause a wider variety of symptoms. Most people associate dry eye with a burning pain or scratchy feeling. Probably the most frequent cause of a blurry computer screen after lasik is dry eye. This happens within the first day.īeyond the first day of lasik the causes of a blurry computer screen after lasik narrow down. As the water is pumped out of the lasik flap, the vision improves. But the cornea has a natural mechanism to pump out the swelling. The swelling of this lasik flap causes everything to be hazy and blurry. The lasik flap absorbs some of this water and becomes slightly swollen. This is all normal and will heal up within the first 24 hours.Īfter the lasik laser treatment, sterile water is used to reposition the lasik flap in place. This will make seeing small details more difficult (not only on the computer but elsewhere in your life as well). While your vision may be better than what it was without glasses and contact lenses, it won't be close to full strength. Everyone will have some blurry vision that first day after lasik. You will have some blurry vision if you are trying to read your computer screen immediately after getting lasik done. But beyond the first day the biggest factors causing the computer screen to be blurry after lasik is dryness and variances in your eye prescription. The first day after lasik, everything is expected to be blurry. But fortunately there are some well known causes for a blurry computer screen after lasik. ![]() The fear of losing vision with lasik is especially evident if it suddenly becomes harder to see and use the computer following a lasik procedure. Many people use computers for their work. Did something go wrong in correcting my vision? We all spend lots of time on a computer these days. ![]() Having some blurry vision after lasik can be scary.
