Endothelial Cell Loss in Penetrating Keratoplasty

Ophthalmology, 1982
Quantitative specular endothelial microscopy was performed on 39 donor corneas before operation and at three and 12 months following penetrating keratoplasty. The central endothelial cell density of these corneas had decreased by 18.3% at three months after operation and by 33.6% at the end of one year.

Endothelial Cell Loss During Penetrating Keratoplasty

American Journal of Ophthalmology, 1978
We studied the central donor endothelium of 27 clear, penetrating corneal transplants with the specular microscope before and after keratoplasty. We examined the donor corneas first, in vitro, while they were immersed in McCarey-Kaufman preservation medium before transplantation. This preoperative examination proved valuable for screening donor corneas,

Corneal Endothelial Cell Loss Following Trephination

Ophthalmic Surgery, Lasers and Imaging Retina, 1988
ABSTRACT The amount of endothelial cell loss that occurs to the donor cornea during the trephination process was evaluated in 40 porcine eyes. A vital staining technique (alizarin red S and acid violet 19) was used to quantify the extent of endothelial damage and removal.

Manual nucleofragmentation and endothelial cell loss

Journal of Cataract and Refractive Surgery, 1997
To compare corneal endothelial cell loss with two cataract surgery techniques: manual nucleofragmentation performed with the Keener nucleus divider and planned extracapsular extraction.Department of Ophthalmology "Memorial Cristóbal Garrigosa," Hospital de l'Esperança, Universitat Autònoma de Barcelona, Spain.Contact specular microscopy was performed ...

Endothelial cell loss in intraocular lens placement

American Intra-Ocular Implant Society Journal, 1978
Endothelial cell counts were done on eyes selected to fall into four categories: unoperated, intracapsular cataract extraction without implantation, and intracapsular cataract extraction with easy or difficult insertion of an intraocular implant. Uncomplicated cataract extraction resulted in less than 9% cell loss.

Endothelial Cell Loss from Intraocular Lens Insertion

Ophthalmology, 1978
ALTHOUGH intraocular implants for replacement of cataractous lenses were first used more than 25 years ago, they have begun to gain acceptance only recently in the United States, and still with considerable caution.1,2 One of the chief reasons for concern has been the high incidence of early and, in particular, late development of bullous keratopathy ...

Endothelial cell loss in irradiated optic nerves

Ophthalmology, 2000
Radiation optic neuropathy usually occurs months to years after exposure of the anterior visual pathways to ionizing radiation. It is characterized by high signal on gadolinium-enhanced T1-weighted magnetic resonance imaging. Radiation-induced endothelial cell damage resulting in blood-nerve barrier breakdown is hypothesized to produce this pattern ...

Immediate Endothelial Cell Loss After Penetrating Keratoplasty

Cornea, 2013
To report the pattern and the extent of corneal endothelial cell loss immediately after a penetrating keratoplasty (PK) is performed.Ten donor corneal-scleral tissues with healthy endothelium were used to perform 10 PK surgeries on cadaver eyes. An 8.25-mm donor graft was placed into an 8.00-mm trephinated recipient bed of the cadaver eye. A 10-0 nylon

Endothelial cell loss after autologous rotational keratoplasty

Graefe's Archive for Clinical and Experimental Ophthalmology, 2004
To investigate whether it may be possible to ascertain the influence of immunological factors on chronic endothelial cell loss by comparing chronic endothelial cell loss after autologous rotational penetrating keratoplasty and after homologous penetrating keratoplasty.For six patients who had undergone autologous rotational penetrating keratoplasty the

Descemet's membrane endothelial keratoplasty tissue type and endothelial cell loss over time

Canadian Journal of Ophthalmology, 2023
To investigate endothelial cell loss after Descemet's membrane endothelial keratoplasty (DMEK) when surgery is performed with surgeon-loaded tissue versus preloaded tissue.The endothelial cell count over time of patients who underwent the last DMEK surgery by a single surgeon with surgeon-loaded tissue from 2014-2017 was compared to that of patients ...
