The Pentacam Corneal Topography System is the
gold standard
for evaluating the cornea prior to and following refractive surgery. When a
cataract develops and surgery is indicated, the Pentacam provides a critical
corneal measurement used to determine the
power of the
intraocular
lens
implanted in the eye. The
Holladay Report (below) generates this
information. Used in conjunction with data obtained from the
Zeiss IOL Master, the appropriate
IOL can be selected. Dr. Rubman was one of the first surgeons in the New York City
area to offer this technology.

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.
