Which tonometry method is known as dynamic contour tonometry and is advantageous for post-op LASIK patients?

Dynamic contour tonometry refers specifically to the PASCAL tonometry system. This method is designed to measure intraocular pressure (IOP) through a contour-matching principle that is more conducive to accurate readings in various corneal states, including those affected by prior surgical procedures like LASIK.

One key advantage of PASCAL tonometry for post-op LASIK patients is that it minimizes the influence of corneal thickness and curvature, which can significantly affect readings obtained with traditional methods, such as Goldmann tonometry. In LASIK patients, the cornea's shape and structure are altered, making it challenging to accurately assess IOP with techniques that rely heavily on the original corneal architecture. The dynamic contour tonometry approach provides a more reliable measure of IOP without being as sensitive to these changes, resulting in better clinical outcomes and patient management post-surgery.

In summary, PASCAL tonometry is particularly well-suited for measuring intraocular pressure in patients who have undergone LASIK due to its ability to obtain accurate readings that are less impacted by the anatomical alterations of the cornea following this type of refractive surgery.
