purpose: to evaluate the results of keratoprosthesis (kps) at labbafinejad medical center. method: in this case-series 29 eyes of 27 patients who underwent kps between 1995-2002 were evaluated for results and complications. results: patients included 22 male and five female subjects. diagnoses included chemical burn (17 cases), stevens-johnson syndrome (three cases), ocular cicatricial pemphigo...

purpose: to characterize keratic precipitate (kp) morphology in different forms of uveitis. methods: one hundred and twenty nine eyes of 93 patients with different forms of uveitis underwent confocal scan and the morphology of kps were determined. differences in kp morphologies among different uveitic groups were evaluated.  results: age ranged from 14 to 67 years (mean: 32.5±11.2) and 58 cases...

PURPOSE To report a patient with refractory keratitis after a Boston type I keratoprosthesis treated with corneal collagen cross-linking (CXL). METHODS Case report. RESULTS A 29-year-old man with a history of chemical burn in the left eye underwent keratoprosthesis implantation. He developed infectious keratitis 4 months after surgery, which did not respond to topical antibiotics. The patie...

Purpose To report the outcomes of implantation of the Boston Type I keratoprosthesis in three patients with Acanthamoeba keratitis (AK), a severe infection that can lead to significant visual loss. Observations Case series reporting three patients with difficult cases of AK that needed multiple corneal transplantations and glaucoma surgeries. All patients were implanted with the Boston Type I...

PURPOSE To compare the University of California Davis experience using the Boston keratoprosthesis with the Boston Keratoprosthesis Study Group's initial report. DESIGN Retrospective chart review. PARTICIPANTS We analyzed 30 eyes of 28 patients who previously underwent Boston type 1 keratoprosthesis surgery at our institution between 2004 and 2008. METHODS Preoperative, intraoperative, an...

In 1771, Guillaume Pellier de Quengsy,1 an ophthalmologist, proposed for the first time the possibility of substituting opacifie corneal tissue by “an artificial cornea”. The proposal was for transparent glass plates to substitute the opaque cornea in order to enhance the transparency of optic media. Improvements in topical and systemic immunosuppression and limbus transplant techniques for tre...

OBJECTIVE To develop a laboratory model to study intracorneal keratoprosthesis implantation. METHODS A combination microkeratome and artificial anterior chamber system was used to create a hinged lamellar keratectomy on 13 human corneas. After reflecting the flap, the posterior stroma was trephined at either 2.5 or 3.0 mm. A model keratoprosthesis was positioned in the bed. The flap was sutur...

PURPOSE To evaluate the anterior keratoprosthesis-cornea interface in eyes with Boston type I keratoprosthesis (Kpro). METHODS In a prospective non-interventional study, patients with Boston type I Kpro underwent ultra-high resolution optical coherence tomography (UHR-OCT) evaluation. The images were used to measure and describe characteristics of the anterior keratoprosthesis-cornea interfac...

BACKGROUND The purpose of this study was to assess whether the resolution offered by two different, recently commercially available high-resolution, spectral-domain anterior segment optical coherence tomography (AS-OCT) instruments allows for detailed anatomic characterization of the critical device-donor cornea interface in eyes implanted with the Boston type I permanent keratoprosthesis.
