Types of Pachymetry and Interpretation of Results<\/h2>\n\n\n\n
It has been shown that patients with corneas thicker than average may have higher pressure, which, however, may not be a cause for concern. Conversely, patients with thin corneas often have underestimated intraocular pressure \u2013 the pressure values are artificially lowered.<\/strong><\/p>\n\n\n\n<\/div>

Contact pachymetry<\/strong> is performed using ultrasonic pachymeters. The examination requires contact between the device’s tip and the patient’s cornea. It is painless because the cornea is anesthetized beforehand with drops. During the examination, several measurements of the central corneal thickness are taken. The results are averaged, allowing for the reading and application of an appropriate correction to the intraocular pressure value. <\/p>\n<\/div>\n\n\n\n\n
Non-contact pachymetry<\/strong> is performed as part of corneal tomography using an ultrasound device. In this case, there is no contact between the device and the cornea, which reduces the risk of infection and discomfort. The advantage of this method is that it provides a thickness profile of the entire cornea, allowing for more precise diagnosis of various corneal conditions \u2013 in contrast to contact pachymetry, which measures corneal thickness only at one selected point. <\/p>\n<\/div>\n<\/div><\/div>\n\n\n\nNOTE: The results of examinations performed by both methods cannot be used interchangeably. Differences may occur between them due to the application of corrections calculated for a specific measurement method. <\/p>\n<\/div>\n<\/div><\/div>\n\n
