Basics of Vision Correction


What is Lasik?

LASIK has become the most popular and successful vision correction procedure worldwide. LASIK (Laser Assisted In Situ Keratomileusis) surgery permanently changes the shape of the cornea, so patients can be freed from the constraints of glasses and contacts.

How does Lasik work?

Lasik is performed in three steps:

1. Corneal flap is created

The eye is prepared by placing numbing drops into the eye and an instrument is used to prevent blinking. In LASIK, a flap is created in the cornea, and is gently lifted.

2. Cornea is reshaped

Using a cool-beam excimer laser, the cornea is reshaped for improved vision. The laser is programmed specifically for you based on your pre-surgery vision evaluation. It is good to know that you cannot actually see the laser treating your eye during surgery.

3. Corneal flap is laid back down

Then the flap is laid back into place, and immediately begins healing. The procedure itself takes only two to three minutes per eye.

What is the difference between LASIK & PRK?

The consultation exam is the same, but the difference is with the surgical process. With LASIK, a flap is created on your cornea then laid back into place and immediately begins to heal. However, with PRK, instead of the flap being laid back down a contact lens in placed over the eye and removed 5 to 7 days later.
