Are There Any Side Effects Associated With Lasik Surgery?

Posted on

Lasik surgery is a very common type of surgery that corrects eyesight and various other conditions involving the eyes. It is most often recommended if you are nearsighted or farsighted, though some people with astigmatism also opt for the surgery. It has a great success rate and few risks, though there are some side effects you should be aware of. Here are some potential risks and side effects that could develop after getting Lasik.

Imperfect Results

Lasik is known for having a high success rate, but that doesn't mean everyone who gets it comes out with flawless, 20/20 vision. It is possible that the surgery gave you undercorrection or even overcorrection. This is a risk you take when getting the procedure performed. While most people do see at least some improvement in their vision, it is possible that you need to occasionally wear glasses for certain things.

Mild Discomfort

The good thing about experiencing mild discomfort after Lasik surgery is the fact that it is usually temporary. You might have light sensitivity, discomfort, or mild irritation after the procedure. This is typically a result of the procedure, and not something you have to deal with for too long. Rest and keep your eyes covered as instructed by your doctor. You may also see starbursts of light, hazy vision, or reduced sharpness of vision, but these are also temporary.

Dry Eyes

Another common side effect of getting Lasik surgery that is typically short-term is having dry eyes. You may have decreased tear production following Lasik, which is what causes your eyes to be dry. This can lead to discomfort as well as blurry vision. Talk to your doctor if it continues and ask about using lubricating eye drops following surgery. You may need different eye drops if the ones you were originally given are not working properly.


Of the different side effects you can get after the procedure, infection is among the most serious. Luckily, it is also not common. If you have signs of an infection, such as redness, warmth to the skin, and a fever, talk to your doctor right away. If it is a mild infection, you shouldn't need much more than antibiotic eye drops and pain relievers for any discomforts.

Risk Factors

In some people, the side effects are more common because they are not a good candidate for Lasik. There are some risk factors you should be aware of before you opt for this procedure. These risk factors are:

  • Thin corneas
  • Large pupils
  • Of older age
  • Proneness to infection
  • Unstable vision
  • Chronic dry eyes
  • Pregnant or nursing
  • High refractive error

Talk to your eye doctor if you are interested in getting Lasik to find out if you are a good candidate.
