Purpose:
To assess changes of central cornea thickness after Excimer laser procedures--photorefractive keratectomy (PRK) and in situ keratomileusis (LASIK).
Material And Methods:
In 80 eyes of 40 patients the Excimer laser procedure was performed. Patients were divided into 2 groups: the 1st after PRK and the 2nd after LASIK procedure. Pachymetric measurements of cornea were performed before and 6 months after procedure.
Results:
In both groups the thickness of the cornea was significantly lower after procedure. In the 2nd group the changes were greater.
Conclusion:
Excimer laser refractive surgery produces significant decrease in cornea thickness. The change in corneal thickness correlates with the change in spherical equivalent refraction.
