Corneal Aberrometry


Lt Col Reynolds
Corneal aberrometry is a test that measures the way light travels through the entire optical pathway, and compares it to the way light travels through an optically perfect eye. Dr. Patel, can you tell us more about corneal aberrometry?

Dr. Patel
Of course, Dr. Reynolds. This assessment is often done using a machine called a wave front aberrometer. By bouncing light off the retina and measuring the imperfections of the eye, the wave front aberrometer creates a three dimensional map of the cornea.

This corneal map is then used for pre-operative screening to design a customized ablation, or tissue removal, that addresses the patient’s unique aberrations, or imperfections. Customized ablation is used in both PRK and LASIK procedures. On surgery day, the information from the map is transferred electronically to the laser, enabling the provider to customize a laser vision procedure to the patient’s particular needs.
