Corneal pachymetry is to measure the thickness of the cornea, often with an ultrasound device called pachymetry, is a procedure quite painless.

The technique is an essential element of pre-operative consultations for laser eye surgery to ensure sufficient corneal thickness.

Very thin corneas may be a cons-indication to laser eye surgery successfully with complications of incomplete healing and residual astigmatism.

The results of the evaluation and pachymetry corneal topography and other studies peformed before the operation are in deciding the appropriate surgical technique for performing this action vision corrective surgery is invaluable.

The latest technology allows the measurement of the thickness of the cornea and corneal topography, a machine that combines a set all be done in an image of the shape of the cornea, the curvature and thickness of a detailed map for thousands of points on the surface of the cornea.
