Pachymetry is a technique that allows the optometrist to accurately measure the thickness of the cornea. At Peter Ivins Eye Care we do so using the latest 3D HD-OCT from Carl Zeiss, allowing very accurate corneal thickness measurements in a quick, painless and non-contact manner (previous methods involved touching the eye). It does not involve eye drops and does not affect vision, meaning driving afterwards is safe.
Corneal pachymetry is important in the early detection and diagnosis of glaucoma and ocular hypertension. It is also potentially important in monitoring corneal disease, diagnosing corneal foreign bodies, and in patients considering LASIK eye surgery as it ensures sufficient corneal thickness prior to surgery to prevent ectasia (abnormal bulging of the cornea).
