To evaluate the intrinsic epithelial and stromal changes postoperative in LASIK and PRK.
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.
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.
Topographic cornea and epithelial thickness imaging shows significant differences when comparing outcomes of LASIK to PRK.
