The cornea is the transparent clear window at the front of the eye. The shape and transparency of the cornea are critical to clear vision. Any condition that affects the clarity of the cornea such as Fuchs' dystrophy or shape of the cornea such as keratoconus can result in poor vision. Other causes including infections, previous surgery including cataract surgery, herpes simplex keratitis and inherited conditions can also cause corneal damage and loss of vision. These can all lead to the need for a corneal transplant.

Modern corneal transplantation techniques aim to preserve the patients own healthy corneal tissue whilst replacing the diseased part. This approach preserves the structural integrity of the eye as far as possible whilst reducing risk of rejection.

Ms de Benito is a corneal transplant surgeon completed a fellowship in corneal transplant surgery at Moorfields Eye Hospital. She performs the latest techniques including DMEK (Descemet's Membrane Endothelial Transplant) for Fuch's dystrophy and DALK (deep anterior lamellar keratoplasty) for patients with keratoconus. A full thickness transplant is rarely needed.
