If you are thinking of undergoing refractive laser surgery, your doctor will use a Pentacam to accurately measure the thickness, contour, and shape of your cornea. The Pentacam uses a rotating camera to image the anterior segment of the eye. The rotating camera, called a Scheimpflug camera, creates a 3D image. The 3D image is an important topographic map used in LASIK, cataract, and glaucoma surgery. It will also be able to tell your eye doctor if you are a candidate for refractive surgery by screening for keratoconus, a degenerative disorder of the eye in which the cornea’s shape is conical. This causes multiple images, light sensitivity, and streaking.

Different Uses of the Pentacam

By measuring the thickness of the cornea at the back and front, the Pentacam can generate 25,000 data points. This large number of points collected on your eye is an extremely accurate way to detail your cornea’s thickness.

The Pentacam can analyze patients to determine if they would be better candidates for intraocular lens implants than simply laser vision correction. In this way, your ophthalmologist will be able to explain to you exactly why you should get IOLs. With a detailed map to look at, the ophthalmologist can help you to better understand what is going on in your eyes.

The Pentacam is yet another high tech way to make sure the ophthalmologist has the most detailed information he or she can have before your procedure.
