The Pentacam

The Pentacam Corneal Topography System is the gold standard for evaluating the cornea. Dr. Rubman was one of the first surgeons in the New York City area to offer this technology which is capable of generating critical data for the pre- and post-surgical cornea.

The Pentacam measurement process takes less than two seconds and minute eye movements are captured and corrected simultaneously. By measuring 25,000 true elevation points, precise representation, repeatability and analysis are guaranteed. These data points are then used to generate corneal maps used for diagnosis and treatment.


The Pentacam images the anterior segment of the eye by a rotating Scheimpflug camera performing a series of slit photographs. This rotating process generates pictures in three dimensions. Because of the rotational imaging, even the center of the cornea can be very precisely measured.
