Long-Term Outcomes of Keratoprosthesis With Biological Haptic: A Review of 25 Years of Single-Center Surgeries.

Purpose: To study the outcome of eyes that underwent surgery for keratoprosthesis with a biological haptic, osteo-odonto-keratoprosthesis (OOKP) or tibia keratoprosthesis, by a single surgeon over a time span of more than 25 years.

Methods: One hundred thirty eyes that had received a keratoprosthesis with a biological haptic between 1994 and 2022 by a single surgeon were included in this retrospective analysis. Main outcome parameters were postoperative best corrected visual acuity, postoperative refractive error, postoperative complications, anatomical and functional survival of the prosthesis as well as comparison of subgroups of the 2 different types (OOKP n = 78; tibia keratoprosthesis n = 52) of keratoprostheses, and subgroup analysis of different indications for surgery.

Suture-Probe Canaloplasty as an Alternative to Canaloplasty Using the iTrack Microcatheter.

Unlabelled: PRéCIS:: Significant intraocular pressure (IOP) reduction was achieved using a novel suture-probe canaloplasty (SPCP) procedure in patients with glaucoma. The effect and low rate of surgical complications were comparable with those of iTrack canaloplasty.

Purpose: Ab externo canaloplasty using the iTrack microcatheter has been established as a safe surgical procedure to treat open-angle glaucoma.

[Keratoprosthesis with Biological Haptic - The Düsseldorf-Offenburg-Experience with Osteo-Odonto- and Tibia-Keratoprosthesis].

In severe ocular surface disease with limbal stem cell deficiency associated with severe dry eye, penetrating keratoplasty is likely to fail. In these cases, and provided the posterior segment is normal, keratoprosthesis surgery (KPro) can achieve visual rehabilitation. In KPros with an autologous biological haptic, a bone-tooth-complex (osteo-odonto-keratoprothesis, OOKPro) or a piece of tibial cortex (tibia-keratoprosthesis, TKPro) is used to carry a PMMA cylinder.

We report on the first implanted Osteo-Odonto-Keratoprosthesis (OOKP) in Switzerland. The procedure is only performed in cases of severe bilateral corneal vision impairment without alternatives (e. g.

Keratoprosthesis surgery.

Purpose: To survey current knowledge of use of keratoprostheses for visual rehabilitation in the dry eye.

Methods: Sections deal with: (1) when a keratoprosthesis is indicated; (2) classification of keratoprostheses; (3) the osteo-odonto-keratoprosthesis (OOKP), its history, indications and contraindications, patient assessment, surgical technique, results and complications, and (4) the AlphaCor, its design, indications, results and complications.

Results: The choice of keratoprosthesis in the severely dry eye is straightforward, as only one device - the OOKP - will work.

Prevalence of ocular manifestations in hereditary hemorrhagic telangiectasia.

Background: Hereditary hemorrhagic telangiectasia (HHT) is a systemic disorder of the fibrovascular tissue. Few data have been published on the frequency of ophthalmologic manifestations. The aim of this study was to assess this frequency.

Standards for modified osteoodontokeratoprosthesis (OOKP) surgery according to Strampelli and Falcinelli: the Rome-Vienna Protocol.

Purpose: To establish a time-proven "gold standard" in modified osteoodontokeratoprosthesis (OOKP) surgery.

Methods: The OOKP is the procedure of choice for restoring sight in patients with corneal blindness caused by end-stage ocular surface disease not amenable to penetrating keratoplasty. Members of the OOKP Study Group met in Rome, Italy in 2001 and Vienna, Austria in 2002 to discuss indications and contraindications, patient selection, surgical technique, postoperative care, and recognition and management of complications of OOKP surgery according to Strampelli and modified by Falcinelli.

Malignant glaucoma due to drug-related angioedema.

Purpose: To report postsurgery angioedema resulting in malignant glaucoma. Interventional case report.

Methods: Three hours after uncomplicated cataract surgery on the right eye, a 61-year-old woman developed angioedema with swelling of the parapharyngeal tissue.

Management and results of retinal detachment after silicone oil removal.

Of the 168 eyes undergoing silicone oil removal from 1993 to 2000, 34 developed retinal detachment after the removal of silicone oil. The management and the results of the 34 eyes were reviewed. Surgical procedures included pars plana vitrectomy, encircling band, cryocoagulation, endotamponade.
