Corneal pachymetry
Corneal Pachymetry
Corneal Pachymetry (pronounced: kor-nee-al pak-uh-mee-tree) is a medical procedure used to measure the thickness of the cornea, the clear front surface of the eye. The term is derived from the Greek words 'korē' meaning 'pupil' and 'pachys' meaning 'thick'.
Procedure
Corneal Pachymetry is typically performed using an ultrasound device that emits high-frequency sound waves. The device is gently placed on the surface of the eye, and the sound waves bounce back to provide a precise measurement of corneal thickness. The procedure is painless and takes only a few minutes to complete.
Importance
The thickness of the cornea can influence eye pressure readings, and it is an important factor in assessing the risk for glaucoma, a condition that causes damage to the eye's optic nerve. A thin cornea can increase the risk of developing glaucoma. Corneal Pachymetry is also used in the evaluation of patients for LASIK surgery, as a thin cornea can increase the risk of complications.
