Corneal endothelial graft surgery can be performed under local or general anaesthetic. The inner, unhealthy membrane of your cornea is carefully removed (âDescemetâs strippingâ) and replaced with a thin disc of donor cornea, that has been prepared with a very precise instrument called a microkeratome (âautomatedâ).Our results show a consistently thin graft which means the visual quality is better.teroid eye drops are very important to prevent rejection of the graft and continue for a year or more. However by the end of the year they are only put in once a day. It is very important not to run out of steroid drops. Your first visit will be a few days after the operation.
