Corneal pachymetry is a test that determines the thickness of the cornea. The knowledge of corneal thickness is used to define the accuracy of intraocular eye pressure (IOP) measurement. The corneal pachymetry examination is also used to evaluate some corneal pathologies such as keratoconus, corneal edema, glaucoma or refractive surgeries.
The two techniques of corneal pachymetry are optical pachymetry, which provides a map of corneal pachymetry and an ultrasound probe (pachymetry acoustics).
In the optical pachymetry, one can obtain a map that shows corneal pachymetry of each point in the corneal surface and allows you to identify the location and value of the thinnest point on the surface of cornea.
The advantages of ultrasound pachymetry (10-20 MHz) include portability and ease of use. These dry contact systems are easy to use, portable, and inexpensive. However, the accuracy of this technique is dependent on the probe's perpendicularity to the cornea, while the reliability depends on precise probe placement.

Pachymetry is a quick and painless test that determines the thickness of the cornea. Corneal thickness, as measured by pachymetry, is important in the field of eye care for a number of reasons. Corneal thickness is critical in refractive surgery procedures such as LASIK (laser-assisted in-situ keratomileusis). It is necessary to understand corneal thickness in order to determine if a person is a candidate for laser vision correction.
Pachymetry is also important in the treatment of glaucoma. Glaucoma is a condition in which the eye pressure (intraocular pressure) rises. Elevated eye pressure can result in nerve fiber loss in the retina, which can lead to blindness or reduced vision.
One type of pachymeter is known as optical pachymeters, and are designed to be mounted on a biomicroscope known as a slit lamp, which is used by eye doctors. This device has no direct contact with the cornea. OCT, or optical coherence tomography pachymetry, is a popular type of optical pachymetry.
Market players and non-profit organizations are focused on raising awareness campaigns and initiatives, this could contribute to the growth of the global corneal pachymetry market over the forecast period. For instance on February 25, 2020, Allergan Inc., a subsidiary of AbbVie Inc., Sightsavers, an international non-governmental organization, and the International Agency for the Prevention of Blindness (IAPB), announced the launch of ‘Keep Sight India,' a community-based glaucoma screening program designed to prevent glaucoma-related vision loss in Ganjam district, Odisha. The program trains healthcare professionals to screen at-risk populations, ensure early and accurate diagnosis, and provide appropriate treatment and long-term care in order to improve the lives of people with glaucoma at all levels of comprehensive eye care.
Market players are focusing on publishing the advantages of their medical devices in journals, which is expected to strengthen their position in the global corneal pachymetry market. For instance, on June 1, 2020, CSO, an International leader in diagnostic ophthalmic instruments, published about MS-39 AS-OCT, and how remarkably the device has performed in refractive surgeries. The MS-39 AS-OCT is the most sophisticated device for analyzing the anterior segment of the eye. It combines placido disk corneal topography with high resolution anterior segment tomography to provide information on corneal surface pachymetry, elevation, curvature, and dioptric power. Surgeons need several ocular metrics in refractive surgeries. Perhaps most importantly, one must rule out subclinical keratoconus (SCKCN) and ensure the absence of ocular surface disease (OSD); refractive surgeons spend a significant amount of time assessing and treating this prior to conducting a surgery. The MS-39 ASOCT has made a significant contribution in all of these functionalities.
Increasing applications of intraoperative optical computed tomography for corneal pachymetry in keratoconus patients is expected to drive the growth of the global corneal pachymetry market. For instance, according to the article published in July 2019, in the e-book ‘A Practical Guide to Clinical Application of OCT in Ophthalmology’, intraoperative optical coherence tomography (OCT) can be used to monitor corneal pachymetry during collagen cross-linking (CXL), a minimally invasive procedure that involves the use of ultraviolet light and eye drops to strengthen the collagen fibers in the cornea, in a safe and effective manner. The benefits of this technology includes providing a detailed profile of corneal thickness in a noncontact manner, which is especially beneficial for monitoring corneal pachymetry in the setting of CXL in keratoconus (KCN) patients when compared to the conventional ultrasound method. OCT has also been used to assess other aspects of the CXL procedure such as in vivo riboflavin penetration into the corneal stroma.
