Purpose Central corneal thickness (CCT) measure is a critical point before refractive surgery. It is well known that surgery can not be performed under a thickness of 500 microns. Methods Pentacam pachymetry was performed in refractive surgery centers in Algeria , Tunisia and Morroco on 1615 eyes of patients originating from North Africa. Results Most of the patients (70%) were aged from 20 to 35 years old.Thirty eight percent(38%) had a CCT between 450 and 500 microns,40% between 500 and 550 microns. Patients with Keratoconus were excluded from this study Conclusion Publications on this subject being very poor, a study on a larger number of patients has to be conducted in order to confirm the relationship between CCT and ethnic origin.
