Laser-assisted in situ keratomileusis (LASIK) has become a wellaccepted and effective procedure for the treatment of a wide range of refractive errors. Microbial keratitis is a potential complication of LASIK with causative organisms, including gram-positive bacteria, atypical mycobacteria, fungi, and viral pathogens. Direct ocular trauma and exposure keratopathy in severely ill patients in int...
purpose: to determine the effect of retained donor descemet membranes (dms) on visual outcomes following deep anterior lamellar keratoplasty (dalk). methods: in this retrospective comparative study, keratoconic eyes undergoing dalk using the big-bubble technique were enrolled. a bared dm was achieved in all cases. a donor cornea without (group 1; 48 eyes) or with (group 2; 22 eyes) dm was sutur...
deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...
THE USE of a Barron artificial anterior chamber (Katena Products, Inc) results in safer and more efficient surgery for deep lamellar endothelial keratoplasty (DLEK) procedures, according to Pavel Studeny MD. Speaking to delegates at the first Cornea Day organised as part of the 10th ESCRS Winter Refractive meeting, Dr Studeny said that the Barron device successfully addresses some of the proble...
dear editor: sir, rabies is an important neurological infection. it is deadly and it is not possible to treat it. despite the attempt for rabies control via animal control and rabies vaccination, there are many reported cases of rabies in each year. basically, the transmission of rabies is due to animal bite. recently, the new mode of rabies transmission, human to human, via transplantation i...
OBJECTIVE To determine whether graft survival over a 5-year follow-up period using corneal tissue from donors older than 65 is similar to graft survival using corneas from younger donors. DESIGN Multicenter prospective, double-masked, controlled clinical trial. PARTICIPANTS One thousand ninety subjects undergoing corneal transplantation for a moderate-risk condition (principally Fuchs' dyst...
OBJECTIVE To determine whether endothelial cell loss 5 years after successful corneal transplantation is related to the age of the donor. DESIGN Multicenter, prospective, double-masked clinical trial. PARTICIPANTS Three hundred forty-seven subjects participating in the Cornea Donor Study who had not experienced graft failure 5 years after corneal transplantation for a moderate-risk conditio...
Case reporting the use of one donor cornea for two transplantation procedures: deep anterior lamellar keratoplasty (DALK) in a case of an imminent corneal perforation caused by herpetic stromal necrosis, and Descemet stripping with endothelial keratoplasty (DSEK) in an eye with pseudophakic bullous keratopathy (PBK). Descemet's membrane (DM), denuded by stromal necrosis, served as the starting ...
