LASIK Eye Surgery

There are a number of different types of laser refractive surgery (laser eye surgery) used to correct vision problems such as nearsightedness, farsightedness and astigmatism. Most types work by reshaping the cornea.

PRK can be an effective treatment for patients with astigmatism.

Explanation:

PRK can correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.

1

During PRK, the ophthalmologist removes the epithelium.

Explanation:

During PRK laser eye surgery, the ophthalmologist removes the epithelium (the surface of the eye) and applies an excimer laser to resurface, blade or vaporize the tissue on the surface of the cornea.

2

LASIK has the longest recovery time, followed by PRK and SMILE.

Explanation:

There’s a longer recovery time after the PRK procedure compared to SMILE or LASIK. It can take six to eight weeks for your vision to fully recover.

3

You'll need to wear a bandaged contact lens after PRK.

Explanation:

Patients require a bandaged contact lens following the procedure, because the epithelium has been removed.

4

Dry eyes are a side effect of LASIK but not PRK.

Explanation:

The side effects from PRK can include dry eyes and glaring halos at night.

What is LASIK Eye Surgery?

LASIK is considered by most refractive surgeons to be the gold standard of laser eye corrective surgery. What does LASIK involve? It involves reshaping the cornea, like all other laser eye surgeries, but specifically, by creating a small flap in the front of the cornea. The cornea is the clear part of the front of the eye.

We create a 100-micron flap, lift the flap up and apply an excimer laser – similar to the same laser that’s used for PRK, to reshape the surface of the eye.
