Purpose
To present the outcomes of Bowman Layer and Stroma onlay Transplant (BLST-o) for the treatment of radial keratotomy.
Setting
Vissum Miranza, Alicante, Spain.
Report of case
2 cases of irregular corneas due to radial keratotomy in symptomatic patients were treated with BLST-o. Both cases showed significant anatomical and functional improvement. One case underwent subsequent laser correction for further visual improvement. The other case developed epithelial ingrowth following suture removal, requiring explantation and a xenogeneic implant.
Conclusion/Take home message
Bowman Layer and Stroma onlay transplant can be a treatment option for radial keratotomy, avoiding more invasive treatment options like DALK or PKP. Graft harvest is safer and more reproducible than that of Bowman Layer Transplant, potentially reducing donor tissue tears, hence reducing donor tissue wastage. It can facilitate subsequent treatments to further improve vision, such as laser. Complications such as epithelial ingrowth are possible, in which case other forms of treatment are still applicable.
