What does a pentacam measure?

Pentacam® measures height (elevation) data. These are converted into curvature (mm) and then converted into power values (diopter).

What is a pentacam used for?

The Pentacam system is commonly used in clinical practice for its myriad functions, including evaluation of cataracts, glaucoma screening, advanced calculations for the power of intraocular lenses, guiding deep anterior lamellar keratoplasty, and imaging of post-LASIK or photorefractive keratectomy (PRK) eyes.

Why do we check pentacam in eyes?

Pentacam is not a routine test. Rather, it is used in diagnosing certain types of problems, in evaluating a disease’s progression, in fitting some types of contact lenses, and in planning surgery. It is commonly used in preparing for refractive eye surgery such as LASIK, EpiLASIK.

How is irregular astigmatism diagnosed?

In these cases, corneal topography, pachymetry, retinoscopy with careful observation of the reflex, a rigid gas permeable contact lens over-refraction, wavefront aberrometry or anterior segment optical coherence tomography (AS-OCT) can all help you identify irregular astigmatism as the culprit.

What is pentacam scan?

The Pentacam Comprehensive Eye Scanner is a rotating camera that photographs both the anterior (front) and posterior (back) surfaces and other areas of the cornea (the front part of the eye).

How much does a pentacam cost?

Some slit-scanning devices: Orbscan (Bausch + Lomb); Pentacam (Oculus); and Galilei G2 (Ziemer). The average cost of these instruments is $50,000. Some manufacturers also offer instruments that combine corneal topography with full optical wavefront aberrometry.

Can you get astigmatism in one eye?

Astigmatism almost always occurs in both eyes. The condition can occur in only one eye but usually is the result of a physical injury.
