1 year posterior corneal changes after Bowman Layer Transplant for keratoconus

To report the posterior corneal changes after Bowman Layer Transplant for keratoconus in a tertiary hospital in the UK.5 eyes of 5 patients receiving Bowman Layer Transplant for advanced keratoconus in Royal Gwent Hospital (Newport, UK) were included. Pre and postoperative posterior corneal astigmatism, posterior Kmean, and back surface elevation were analysed.No significant changes were seen in the posterior corneal astigmatism, posterior Kmean, or back surface elevation between the pre- and postoperative period.This results would support the idea that the corneal changes seen after Bowman Layer Transplant are mainly in the anterior corneal surface.
