Corneal pachymetry is the process of measuring the thickness of the cornea.A pachymeter is a medical device used to measure the thickness of the eye's cornea.It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery [1] and is useful in screening for patients suspected of developing glaucoma among other uses.
People with early keratoconus often notice a minor blurring or distortion of their vision, as well as an increased sensitivity to light, so they may visit their clinician seeking corrective lenses for reading or driving. [13] [14] At early stages, the symptoms of keratoconus may be no different from those of any other refractive defect of the

Dog with atopic dermatitis, with signs around the eye created by rubbing. Atopy is a hereditary [3] and chronic (lifelong) allergic skin disease. Signs usually begin between 6 months and 3 years of age, with some breeds of dog, such as the golden retriever, showing signs at an earlier age.
Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [ 2 ] Keratoglobus , a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea.
Keratoconus in itself is a pattern of the entire cornea, therefore every measurement just focusing on one layer, might not be enough for a state of the art diagnosis. Especially early cases of keratoconus might be missed by a plain topographic measurement, which is critical if refractive surgery is being considered. [7]
