What Is Laser Eye Surgery and Why Is it Useful?

Laser Eye Surgery

People throughout the world suffer from poor vision and require glasses or contact lenses so that they can see properly. In some cases, these people may opt for laser eye surgery to improve their overall vision and eliminate the need for glasses.

Basically, laser corrective surgery works by reshaping the cornea (front) of your eye to allow light to be focused properly on the retina at the back of the eye. It comes in a number of different forms, and we’ve outlined a few of the most popular below.

As always, the best thing to do if you think laser eye surgery could be a good option for you is to speak with your local optometrist.

Why Should I Consider Laser Eye Surgery?

Basically, poor vision can impact your life – as I’m sure you know if you’re someone who has to wear glasses or contact lenses. To put it simply, laser eye surgery can improve your vision and result in a dramatic improvement in your overall quality of life. Some of the reasons why you should at least think about it include:

  • You won’t have to wear glasses or contact lenses to be able to see properly any more.
  • Your overall vision will be improved, which will impact numerous aspects of your life in general.
  • It’s relatively affordable and a safe procedure.
  • A huge percentage of people achieve 20/20 vision following the surgery.

However, there are a few different types of laser eye surgery, which we’ve outlined below.

What Are the Main types of Laser Eye Surgery?

There are three main types of laser eye surgery that we think are worth touching on.


SMILE, or small incision lenticule extraction, is a modern procedure designed to correct both astigmatism and myopia. It has a very short recovery period, few side effects and, in general, excellent outcomes. Additionally, it’s very predictive, which means that the procedure is usually successful.


LASIK, or laser assisted in-situ keratomileusis, is commonly used as a treatment for short-sightedness, long-sightedness and astigmatism. Usually, it’s reserved for those younger than 40 years old. In short, LASIK involves reshaping the surface of the eye to correct your sight problems. Improvement is near instant, and the treatment takes just 15 minutes.


Finally, doctors might choose to use an ASA procedure in place of LASIK if your eyes are in poor condition. It has similar outcomes, but will usually come with a longer recovery time and more discomfort.

Getting Your Laser Eye Surgery

If you have poor vision, some form of laser eye surgery could be exactly what you’re looking for. In general, it’s relatively inexpensive compared to most other surgeries, and it doesn’t come with an overly long recovery period.

The three main types of laser eye surgery are LASIK, ASA and SMILE. Each is used in specific situations with specific outcomes, but all three have a great success rate. Ultimately, you should speak with your local laser surgery specialist if you’re interested in finding out whether there’s a solution that works for you.
