Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft). When the entire cornea is replaced it is known as penetrating keratoplasty and when only part of the cornea is replaced it is known as lamellar keratoplasty.
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.
As a progressive, chronic condition, signs and symptoms of Fuchs dystrophy gradually progress over decades of life, starting in middle age. Early symptoms include blurry vision upon wakening which improves during the morning, [2] as fluid retained in the cornea is unable to evaporate through the surface of the eye when the lids are closed overnight.
A face transplant is a medical procedure to replace all or part of a person's face using tissue from a donor. Part of a field called "Vascularized Composite Tissue Allotransplantation" (VCA) it involves the transplantation of facial skin, the nasal structure, the nose, the lips, the muscles of facial movement used for expression, the nerves that provide sensation, and, potentially, the bones ...
Video-assisted thoracoscopic surgery (VATS) is a type of minimally invasive thoracic surgery performed using a small video camera mounted to a fiberoptic thoracoscope (either 5 mm or 10 mm caliber), with or without angulated visualization, which allows the surgeon to see inside the chest by viewing the video images relayed onto a television screen, and perform procedures using elongated ...
Microsurgery is a general term for surgery requiring an operating microscope.The most obvious developments have been procedures developed to allow anastomosis of successively smaller blood vessels and nerves (typically 1 mm in diameter) which have allowed transfer of tissue from one part of the body to another and re-attachment of severed parts.
The TESSYS method (transforaminal endoscopic surgical system) is a minimally-invasive, endoscopic spinal procedure for the treatment of a herniated disc.It was a further development of the YESS method by the Dutch Dr Thomas Hoogland in the Alpha Klinik in Munich in 1989 and was first called THESSYS (Thomas Hoogland EndoScopic SYStem).
Endoscopic endonasal surgery is a minimally invasive technique used mainly in neurosurgery and otolaryngology. A neurosurgeon or an otolaryngologist, using an endoscope that is entered through the nose, fixes or removes brain defects or tumors in the anterior skull base .
