It has recently been determined that the thickness of an individual's cornea can influence the pressure reading and lead to under or over-estimates. For this reason we now perform Ultrasound Corneal Pachymetry on all our patients as a baseline, to determine corneal thickness. Having this measurement allows us to get a better understanding of your eye pressure readings. This new technique is vital in the diagnosis of Glaucoma. It is also a very important piece of information for patients who are considering LASIK surgery and to monitor the progression of certain corneal conditions such as Fuchs Endothelial dystrophy and Keratoconus.
This test is simple, painless and takes a few seconds. Please let us know if you haven't had it done – it is very important for determining an accurate pressure.
