Is there any problem when cxl is used for stabilizing post rk incision?
Our keratoconus surgeon notes that in the journal of cataract and refactive surgery there is a case report by Dr. Abad which deals with this situation. A patient with rk and ak suffered from ectasia or corneal bulging. On undergoing treatment with cornea cross linkage or cxl, there was a wound gape which required corneal suture. The good news is that the wounds healed with scarring and there was improvement in vision and the shape of the cornea.
RK or radial keratotomy was developed by Fyodrov in russia. Previous techniques to stabilize the instability of these incisions include suturing and intacs. AK is arcuate keratotomy. Today this is not performed, It has evolved into the popular LRI or limbal relaxing incisions.
