Perimetry and Ultrasound Pachymetry
A pachometer is an instrument that measures the thickness of the cornea in microns.
Ultrasound Pachymetry is a painless procedure that takes less than 5 minutes. Measurements allow the optometrist to determine if a patient is a good candidate for refractive surgery. Measurements allow the optometrist to determine the accuracy of intraocular pressure measurements.
Perimetry is also used at the vision clinic to test visual field analysis of patients, which helps diagnose diseases such as glaucoma or neurological problems.
