Abstract 
 
Purpose:
 

To evaluate the intrinsic epithelial and stromal changes postoperative in LASIK and PRK.

 
Methods:
 

55 consecutive eyes were evaluated with the Artemis II HFU, the Pentacam HD, and the Optovue cornea OCT for topographic cornea thickness with all 3 devices and cornea epithelial topography. In addition, age, UCVA, BSCVA, refraction, cylinder (C), tomography, and endothelial counts were reviewed.

 
Results:
 

There were 28 LASIK cases (group A) and 27 PRK cases (group B) that were studied. There were significant changes between the findings of group A versus group B.The LASIK eyes (group A) demonstated significant epithelial thickness regularity and were uniformly closer to normal than group B: 49um vs 58um. Group B demonstrated a significant difference in tomographic cylinder (IHD:index of height decentration) when compared to group A.

 
Conclusions:
 

Topographic cornea and epithelial thickness imaging shows significant differences when comparing outcomes of LASIK to PRK.
