Penetrating Keratoplasty (PK) - University of Iowa
2015年5月21日 · Penetrating Keratoplasty (PK) PK is a full-thickness transplant procedure, in which a trephine of an appropriate diameter is used to make a full-thickness resection of the patient's cornea, followed by placement of a full-thickness donor corneal graft. Interrupted and/or running sutures are placed in radial fashion at equal tension to minimize ...

2015年5月21日 · Penetrating Keratoplasty (PK) PK is a full-thickness transplant procedure, in which a trephine of an appropriate diameter is used to make a full-thickness resection of the patient's cornea, followed by placement of a full-thickness donor corneal graft.
Descemet Membrane Endothelial Keratoplasty (DMEK) - University …
2016年4月13日 · Descemet Membrane Endothelial Keratoplasty (DMEK) DMEK is a partial-thickness cornea transplant procedure that involves selective removal of the patient's Descemet membrane and endothelium, followed by transplantation of donor corneal endothelium and Descemet membrane without additional stromal tissue from the donor.
Descemet Stripping Automated Endothelial Keratoplasty (DSAEK)
2016年4月5日 · Video 3: Descemet stripping automated endothelial keratoplasty (DSAEK) is an endothelial replacement procedure in which dysfunctional corneal endothelium is replaced with a graft consisting of donor endothelium and a thin layer of posterior stroma to facilitate handling of the tissue. This case was performed for severe corneal edema secondary ...
Laser Assisted Keratoplasty - University of Iowa
2009年10月30日 · Laser Assisted Keratoplasty The first paper detailing the use of the femtosecond laser to prepare human donor and host corneas for transplant was published in 2007.[9] This increased application has now made it possible to make advanced shaped corneal cuts by laser, decreasing the need to do a technically difficult and time-consuming manual ...
Keratoprosthesis - University of Iowa
2016年4月8日 · KPro placement offers relatively fast visual rehabilitation. The devices are amenable for use in many situations in which other types of keratoplasty are not an option. There is significant long-term risk of complications for those with a keratoprosthesis. Because the KPro is a foreign body, there is risk of infection or extrusion of the device.
Deep Anterior Lamellar Keratoplasty (DALK) - University of Iowa
2016年3月10日 · Deep Anterior Lamellar Keratoplasty (DALK) DALK is a partial-thickness cornea transplant procedure that involves selective transplantation of the corneal stroma, leaving the native Descemet membrane and endothelium in place. A trephine of an appropriate diameter is used to make a partial-thickness incision into the patient's cornea, followed by ...
Atlas Entry - Kaye dots in a penetrating keratoplasty graft
Kaye dots are white punctate epithelial opacities located in the epithelium anterior to the suture line of a corneal graft. The dots represent epithelial cells in various stages of degeneration on histopathology and it has been hypothesized that they may result from an epithelial response to the area of tissue angulation. Kaye dots are not ...
Fuchs Endothelial Corneal Dystrophy: - University of Iowa
2024年1月22日 · Keratoplasty, or corneal transplantation, involves replacing damaged portions of the patient’s cornea with functional graft tissue from a deceased donor (i.e. allogeneic transplantation). The corneal endothelium is the damaged component in patients with FECD.
Pseudophakic Bullous Keratopathy: - University of Iowa
2005年11月17日 · Right eye: Full-thickness penetrating keratoplasty (PKP) graft with severe corneal edema (pachymetry measured 900+ um thick) and a dense paracentral scar. Anterior chamber IOL and correctopia of the pupil; Left eye: Edematous cornea (pachymetry measured 826 um thick centrally) and microcysic epithelial changes with folds in Descemet's membrane.
