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.
The procedure may also reduce the chances of dry eye symptoms after surgery. Due to the PRK procedure not requiring a surgical flap, athletes or individuals concerned with trauma introduced by the flap may see benefits to LASEK. Patients that wear contact lenses will typically need to stop wearing these for a specified time before the procedure ...
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]
A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury, and can also allow doctors to surgically implant devices, such as deep brain ...
After the decompression is complete, the wound is flushed clean with saline solution. The dura is closed in a watertight fashion. The skull is reconstructed and the overlying tissues are closed in multiple layers. The patient is allowed to wake up and is taken to an intensive care unit or other close observation unit. [7]
After the procedure, the patient is usually transferred to the intensive care unit (ICU), where intubations are removed if not already done in the operating theater. They usually exit the ICU by the following day, and four days later, if no complications occur, the patient is discharged from the hospital.
Local anaesthesia is normally used; the procedure is usually quick and causes little or no pain and minor discomfort. Recovery sufficient for most daily activities usually takes place in days, and full recovery takes about a month. [5] Well over 90% of operations are successful in restoring useful vision, and there is a low complication rate.
