CORNEAL TRANSPLANT SURGERY
In the last 10 years there has been a revolution in how corneal transplant surgery is performed. Instead of transplanting the entire cornea, only the diseased portion is transplanted. In keratoconus, this means leaving the endothelial cell layer undisturbed and only transplanting the anterior (front) part of the cornea (Deep anterior lamellar keratoplasty or DALK).
This has the advantage of removing the main risk factor for corneal graft failure, namely endothelial rejection. In endothelial disease such as Fuchs Endothelial Dystrophy, pseudophakic bullous keratopathy or corneal graft failure, this is done with selective endothelial keratoplasty (DSEK, DSAEK or DMEK) where only 0.1 – 0.2mm of the donor cornea is inserted through a keyhole incision.
Ollie Storey was treated by Mr Allon Barsam who carried out a deep anterior lamellar keratoplasty to treat keratoconus.
