What is LASIK and PRK?

IN THIS VIDEO I PROVIDE A BRIEF EXPLANATION

Everything you need to know about LASIK and PRK

IN THESE TOGGLES YOU WILL FIND THE DETAILS YOU ARE LOOKING FOR

LASIK

LASIK is the most popular and well-known type of laser eye surgery. It can be used to treat short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism.

PRK

PRK is one of the original forms of laser eye surgery. It is the predecessor of LASIK and LASEK and has successfully transformed the vision of millions of people since the 1980s.

PRK corrects astigmatism, myopia (short-sightedness) and hyperopia (far-sightedness), and is best suited for patients who have chronically dry eyes or thin corneas.

LASIK

LASIK is a quick and pain-free procedure that corrects your refractive error, so you no longer need glasses.

This treatment can be carried out produce clearer, sharper vision in just 15 minutes.

The procedure involves using a femtosecond laser to create a thin flap on the surface of the cornea. The flap is then peeled open and a second excimer laser is applied to reshape the deeper layers of the cornea to correct the focus of the eye. The flap is then replaced and heals typically within five days of surgery.

PRK

PRK is a quick and pain-free procedure that corrects your refractive error, so you no longer need glasses.

First anaesthetic drops are applied to the eye to numb the area and prevent all discomfort during the treatment.  Then a device is used to hold the eyelids apart to stop the eye blinking. We then gently remove the outer layer of the cornea, so an area is exposed for a laser to reshape the cornea. The laser reshapes the cornea so light can enter the eye and properly focus on the retina allowing for clear vision.

After the treatment, we place a soft contact lens onto the cornea to protect your eye.

The recovery time for PRK is longer than other laser vision correction options, this is because it can take several days for new epithelial cells to regenerate and cover the outer layer of the eye. This can cause patients more discomfort during the first few days of recovery.

However, compared to other laser eye surgery treatments, such as LASIK and LASEK, there is no risk of corneal flap complications.

LASIK

To be suitable for LASIK, you must have:

  • A stable prescription
  • A healthy eye
  • A strong cornea that can withstand the effects of surgery

We can assess your suitability for LASIK with a thorough eye examination that involves a series of scans which examine the health of the eye, the thickness of the cornea and your prescription.

If the results of your examination suggest that you are not suitable for laser eye surgery, we can discuss alternative treatments, such as lens implant surgery. 

PRK

To ensure you’re suitability for PRK laser eye surgery, you are required to have an eye exam.

The eye exam includes an evaluation of:

  • The moistness in your eye
  • Corneal curvature
  • The size of your pupils
  • Corneal thickness

After LASIK and PRK, you should have 20/20 and be free from the hassle of glasses and contact lenses.
