Corneal Transplant

Mr Barsam uses the latest small incision lamellar techniques


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.

Derek - Corneal Transplant Surgery

“My trust in Allon Barsam exceeded expectations. My own personal experience of Allon Barsam is of his outstanding clinical skills in cornea transplants: he has operated surgically on both my eyes with great success. However I also know that his considerable experience, skilled approach and patient care extends to his extensive laser surgery work on eye correction and vision improvement and I have no hesitation in recommending him and his team to those considering taking what is a very important step. Our sight is one of our most valuable assets and deserves care of the highest standard which Allon Barsam provides.”
