Orbscan / Topography / Topolyzer

These three terms refer to the process in which the health of the cornea is evaluated through imaging. The purpose of the test is to determine various factors of health of the cornea including thickness, surface power and the shapes of the front and the back of the cornea.

This test is among the most important diagnostic tools available to eye experts. It is often used to diagnose the onset of various eye issues. The results of the test are instrumental in developing a clear picture of the health of the health of the cornea.

Orbscan is often the test that doctors use to determine whether a patient is a good fit for corrective procedures such as LASIK.

The Procedure Of Orbscan

The equipment for Orbscan comprises of a digital camera and equipment that projects rings onto the cornea. These projected rings are used as guide to measure the thickness of the cornea. This is particularly important for LASIK procedure because the thickness of the cornea could not go below a certain limit. Thus, the role of the procedure in LASIK could not be overstated. An average cornea is about 500 micron thick. Using the test results as a guide, the procedure of LASIK reshapes the cornea.
