LASIK: Measuring Your Cornea With Pachymetry

LASIK eye surgery works by altering the shape of your cornea, allowing light to focus correctly at a single point. In order to access the part of your cornea that needs to be altered, a flap is created in the outermost layer (called the epithelium). In order to be a good LASIK candidate, your cornea must be thick enough to support the creation of a flap.

Pachymetry is the process of measuring the thickness of your cornea, using a medical device called a pachymeter. This method is used to determine your candidacy for LASIK, LRI surgery, and also to diagnose Keratoconus. Additionally, pachymetry is necessary for glaucoma patients, since the thickness of your cornea can have a significant effect on the accuracy of intraocular pressure readings.

If pachymetry reveals that your cornea is too thin for LASIK surgery, you may still be able to benefit from life-changing vision correction through an alternative procedure, such as LASEK, epi-LASIK, or PRK.
