LASIK is the most frequently performed elective surgery in North America. This highly effective outpatient procedure is performed on 1,000s of people a year.

LASIK eye surgery is used to correct the following vision problems:

  • Myopia
  • Hyperopia
  • Astigmatism

As you research LASIK procedures and LASIK providers, you will most likely find that there are many variations of the LASIK procedure and many different kinds of technology used for LASIK eye surgery. Understanding the differences in LASIK procedures is important in helping to determine which LASIK procedure will work best for you.  The biggest difference between LASIK procedures is the technology used to evaluate a patient’s refractive error.

Laser vision correction is a term used to describe a variety of laser vision correction treatments for common vision correction problems.

The most commonly referred to laser eye surgery procedure is LASIK. LASIK stands for Laser-Assisted In Situ Keratomileusis. This literally means, “to shape the cornea within, using laser.” LASIK can be used to reduce or eliminate nearsightedness (myopia), farsightedness (hyperopia), or astigmatism. These conditions are due to abnormal curvature of the cornea (the clear window of the eye).

During LASIK, an instrument called a microkeratome or a laser called an Intralase will be used to elevate a very thin surface on the front surface of the cornea. This layer is created to allow the laser light to etch the new corneal curvature in the cell layers underneath. The surface layer is then put back in place to protect the newly reshaped cornea. The average LASIK procedure takes about 7 to 10 minutes per eye. LASIK is a remarkable medical advancement that allows most patients to go from 20/400 — or even 20/1000 — to 20/20 the day following surgery.

Patients will walk away a few moments after this laser eye procedure, but are encouraged to rest as much as possible the day of surgery. A follow up visit with your eye surgeon will be arranged to ensure proper healing as well determine how much your vision has improved.

If you are interested in laser vision correction, Crown Laser Center can answer your questions in detail and help you determine which procedure is right for you.

At Crown Laser Center, we offer three different types of LASIK Procedure. 

  • Custom Bladeless LASIK is a laser vision correction procedure that helps your Crown Laser Center LASIK surgeon customize the laser treatment to your individual eyes.
  • PRK works by reshaping the cornea using an excimer laser, allowing light entering the eye to be properly focused onto the retina for clear vision.  The cornea’s entire epithelial (outer) layer is removed to expose the area and no flap is created.
