PACHYMETRY

Corvis-ST supports pachymetry, a simple and painless test that measures corneal thickness for LASIK screening, glaucoma evaluation, corneal disease management, and post-surgery follow-up.

Pachymetry is a simple, painless test that quickly measures the thickness of the cornea.

It is generally used for the following:

To determine if the patient's cornea is suitable for LASIK or if another variety of treatment should be considered
In routine eye exams when the doctor suspects any corneal abnormality
As an essential part of the glaucoma examination
To manage or treat various corneal diseases, such as Fuch's dystrophy, bullous keratopathy, and keratoconus
After-surgery evaluation of patients undergoing corneal transplant
After-surgery follow-up and evaluation of corneal transplant rejection

Pachymetry can also assist in evaluating whether the current medical treatment is working well, and is often an accurate means of assessing the progression of various eye disorders.

Corneal Thickness and Glaucoma

The thickness of your cornea may significantly impact readings of your intraocular pressure. If you have thin corneas, your eye pressure may read artificially low. Similarly, if you have a thicker cornea, you may register as having a higher intraocular pressure, leading your eye doctor to conclude that you have glaucoma and start treatment when you may actually have no risk.

Pachymetry and LASIK

Pachymetry should be done if you are considering LASIK to ensure that your corneas are thick enough to support the corneal flap. If you do not qualify for LASIK, you may be able to use one of the alternate laser vision corrections such as EpiLASIK or implantable contact lenses (ICL).
