Optical pachymetry is the process in which an eye doctor measures the thickness of a patient's cornea. A device called a pachymeter is used to get the measurements needed, which can be used prior to certain eye surgeries — such as refractive surgery — or also to look for signs of glaucoma. Pachymeters are non-invasive and many of today's devices use the latest technologies to ensure very accurate measurements.

| Optical Pachymetry | Inquire | The optional, non-contact pachymetry is based on Scheimpflug images and makes precise non-contact measurement of the corneal thickness possible. - Measurement of the corneal thickness in the apex and the minimum corneal thickness in the entire measuring area - Measurement of 600 absolute height values on a horizontal 4 mm cut through the apex - Presentation of the corneal thickness profile in the form of a diagram. Automatic adjustment of the scaling of the Pachymetry measurements for better presentation of the individual thicknesses - Pachymetry-based correction of the separately measured intraocular pressure |
