Insightful Answers about iLASIK and PRK Surgery

INSIGHTFUL ANSWERS

What is the difference between iLASIK vs PRK?
The biggest difference between iLASIK and PRK is iLASIK involves the creation of a thin-flap within the cornea.

  • iLASIK we create a thin flap that is folded back, the laser reshapes the eye and the flap is then replaced andthe eye begins to heal.
  • PRK no flap is created. A thin skin layer called the epithelium is gently removed, the laser reshapes the eye and a protective contact lens is placed in the eye and healing begins. The healing time of PRK is longer than iLASIK.

At The Eye Institute We use the wavescan testing that gives us your personalized treatment for iLASIK and PRK. We also use the same VISX S4 laser for both iLASIK and PRK correction.

Does iLASIK hurt?

Numbing eye drops are administered prior to surgery, so most patients having iLASIK do not experience pain. There is some pressure during the creation of the flap, this step takes 10-15 seconds. Following iLASIK, once the numbing eye drops wear off, most patients experience light sensitivity, irritation, watery eyes and a dry or scratchy feeling for a few hours.

Does PRK hurt?

Numbing eye drops are administered prior to surgery, so most patients having PRK do not experience pain. Following PRK, once the numbing eye drops wear off, most patients experience light sensitivity, irritation, watery eyes and a dry or scratchy feeling for a few hours. Patients having PRK tend to have more discomfort, for a longer period of time, than patients having iLASIK. This is managed with medications and eye drops.

Can I feel the laser?

You will not be able to feel the laser reshaping your eye. You will, however, be able to smell the vapor this laser creates. Most laser treatments are between 15 and 45 seconds.

What happens if I move my eye?

iLASIK and custom PRK utilize advanced tracking technologies that monitor youreye position hundreds of times a second. If your eye moves, the laser works to keep the treatment aligned. The surgeon is also monitoring the treatment.

When can I…

Go back to work? iLASIK the next day, PRK generally 4-5 days. With PRK the vision at this stage is “functional” but not perfect.
Wear Makeup? One week after either iLASIK or PRK.
Exercise? One day after either iLASIK or PRK, although vigorous exercise is to be avoided for one week.
