Descemet membrane endothelial keratoplasty (DMEK) is a method of corneal transplantation that involves the removal of a thin sheet of tissue from the posterior (innermost) side of a person's cornea to replace it with the two posterior (innermost) layers of corneal tissue from a donor's eyeball.
The DMEK procedure is a 'like for like' replacement of the diseased part of the cornea with visual rehabilitation to 20/40 or better in 90% of cases and 20/25 or better in 60% of cases within the first three months. Rejection rates are lower (1%) and visual recovery is faster than any other form of corneal transplantation.
In the last one and half year, many patients have been benefitted by PDEK surgery.1,6,7 Early visual recovery and less post operative inflammation is the main advantage. Young donor eyes seemed to have made a huge difference in the visual quality and functional outcome.
The corneal endothelium is a single layer of endothelial cells on the inner surface of the cornea.It faces the chamber formed between the cornea and the iris. The corneal endothelium are specialized, flattened, mitochondria-rich cells that line the posterior surface of the cornea and face the anterior chamber of the eye.
It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...
Damage control surgery is surgical intervention to keep the patient alive rather than correct the anatomy. [ 1 ] [ 2 ] It addresses the "lethal triad" for critically ill patients with severe hemorrhage affecting homeostasis leading to metabolic acidosis , hypothermia , and increased coagulopathy .
Reconstructive surgery is a term with training, clinical, and reimbursement implications. It has historically been referred to as synonymous with plastic surgery. [1] In regard to training, plastic surgery is a recognized medical specialty and a surgeon can be a "board-certified" plastic surgeon by the American Board of Plastic Surgery. [2]
Arthroscopic surgery. Minimally invasive procedures were pioneered by interventional radiologists who had first introduced angioplasty and the catheter-delivered stent.Many other minimally invasive procedures have followed where images of all parts of the body can be obtained and used to direct interventional instruments by way of catheters (needles and fine tubes), so that many conditions ...
