Special training in graft preparation is critical when using tissue from diabetic donors in Descemet’s membrane endothelial keratoplasty, a speaker said at the European Society of Cataract and Refractive Surgeons meeting in Barcelona. Francis W. Price Jr., MD, OSN Cornea/External Disease Board Member, described challenges involved when using diabetic donor tissue in DMEK, Descemet’s stripping endothelial keratoplasty and penetrating keratoplasty.
Minimally invasive glaucoma surgery promises to deliver modest IOP lowering for mild and moderate stages of open-angle glaucoma with minimal tissue disruption and complications. Narrow angles and advanced glaucoma stages are considered relative contrai…
With careful use, intraoperative aberrometry provides valuable and otherwise unattainable data to improve refractive outcomes in cataract surgery, according to one surgeon.“We don’t know what the surgically induced astigmatism is going to be until we make our incision, and although there are devices out there that are starting to measure posterior corneal curvature better, I think aberrometry combines those two hard-to-obtain pieces of information the best,” John P. Berdahl, MD, said at OSN New York 2015.
Glaucoma can be a difficult management problem in a subset of patients, even for the most experienced glaucoma specialists. The treatment spectrum includes drugs, trabeculoplasty, microincision glaucoma surgery and traditional glaucoma surgery.While many use glaucoma medications as their initial treatment modality, others use selective laser trabeculoplasty for the initial IOP control. The majority of glaucoma patients’ IOPs may be controlled with one or more topical medications, but there is a subset of patients whose IOPs are not adequately controlled even on maximum medical therapy. Additionally, some patients have limited choice (Read more...)
Pupil expansion devices are an essential element of cataract surgery in cases of non-dilating pupils. An adequately sized capsulorrhexis with an adequate and appropriate exposure of the surgical space ensures the ease of surgery. Without the use of a proper pupil expansion device, a small pupil may cause complications such as sphincter tears, intraoperative bleeding, zonular dialysis and, in extreme cases with prolonged struggle, possibly even posterior capsular rent or nucleus drop. Prolonged surgical time and increased maneuvering may result in postoperative complications such as striate keratopathy, uveitis, secondary glaucoma, (Read more...)
WAIKOLOA, Hawaii — At Hawaiian Eye, James P. McCulley, MD, FACS, FRCOphth, gives reasons for his off-label use of fourth-generation fluoroquinolones as prophylaxis before, during and after cataract surgery.
