Study about Corneal Collagen Cross-Linking Mushroom Shape Demarcation Line Profile after Limited Bowman’s Membrane Removal by Phototherapeutic Keratectomy | Chapter 14 | New Horizons in Medicine and Medical Research Vol. 4

 A instance of keratoconus was treated using mechanical epithelial debridement (at an 8.5 mm zone), limited PTK (at a 5.0 mm zone and 10 m depth), and CXL. The removal of the Bowman's layer resulted in a mushroom-shaped demarcation line profile on AS-OCT, showing that the removal of the Bowman's layer may have contributed to the increased depth of the corneal stromal demarcation line.

Mechanical epithelial debridement (at an 8.5 mm zone), PTK (at a 5.0 mm zone and in a 10 m depth), and CXL were performed on a twenty-one-year-old male with progressive keratoconus. There were no intraoperative or early postoperative problems discovered. Anterior segment optical coherence tomography indicated a mushroom-shaped profile in the corneal stromal demarcation line depth.

The loss of Bowman's layer appears to result in a deeper corneal stromal demarcation line. Bowman's removal could result in corneal thinning as a result of increased evaporation. Despite the fact that the significance of Bowman's layer in the CXL technique is uncertain, this finding suggests that removing it could increase the depth of CXL therapy.
