Abstract
Purpose :
To report a corneal collagen cross-linking (CXL) mushroom shape demarcation line profile after limited Bowman’s membrane removal by phototherapeutic keratectomy (PTK).
Methods :
Case report.
Results :
A twenty-one-year-old male with progressive keratoconus underwent mechanical epithelial debridement (at an 8.5 mm zone) followed by PTK (at a 5.0 mm zone and in a 10 μm depth) and CXL. No intra- or early postoperative complications were found. Evaluation of the corneal stromal demarcation line depth using anterior segment optical coherence tomography revealed a mushroom shape profile.
Conclusion :
It seems that removal of the Bowman’s layer leads to greater depth of the corneal stromal demarcation line.
Keywords: Cross-linking, keratoconus, phototherapeutic keratectomy..
