How do doctors determine corneal thickness when you decide to undergo the lasik surgery?

In brief: Several ways

There are a number of ways to measure corneal thickness.
Ultrsound is the most common way. Also, there are a number of optical ways to determine corneal thickness using different forms of topography or optical coherence tomography (oct).

If the cornea is too thin, this may be a contraindication to LASIK surgery. PRK may work instead.

In brief: Careful measurement

There are 2 major ways to measure corneal thickness: ultrasound, which works similarly to what is used to "look" at a developing fetus; and optical coherence tomography (oct), which uses light rays to do the same thing.
Neither is painful (in fact, you cannot feel it being done).

In brief: Pachymeter

Corneal thickness is measured using an ultrasonic pachymeter. It is painless and takes only a few seconds.

Ultrasound and corneal imaging are very common, and quickly done in the office routinely.
