PURPOSE To design a surgical technique for transplantation of posterior corneal tissue, while leaving the recipient anterior cornea intact. METHODS In human cadaver eyes, and in a cat and monkey model, recipient eyes had an 8.0-mm limbal incision made with a diamond blade set to 50% of central pachymetry. A stromal pocket was created across the cornea,(More)
BACKGROUND/AIMS To study the intravitreal antibiotic concentrations and the efficacy of an intravitreal dosing regimen to treat patients with postoperative bacterial endophthalmitis. This regimen, based on pharmacokinetic/pharmacodynamic considerations, relies on a repeat antibiotic injection of a lower dose than is generally used. METHODS In consecutive(More)
BACKGROUND The incidence of contact-lens-associated microbial keratitis is uncertain and its related morbidity in the general population of contact-lens wearers is not known. We examined these issues in a prospective epidemiological study. METHODS We surveyed all practising ophthalmologists in the Netherlands to identify all new cases of microbial(More)
PURPOSE To describe a new surgical technique for posterior corneal transplantation. METHODS An elderly patient had painful, pseudophakic bullous keratopathy with low visual potential. Through a 9.0-mm scleral tunnel incision, a midstromal pocket was dissected across the cornea, and a posterior lamellar disk 7.0-mm in diameter, which consisted of posterior(More)
AIMS To describe a new surgical technique for deep stromal anterior lamellar keratoplasty. METHODS In eye bank eyes and sighted human eyes, aqueous was exchanged by air, to visualise the posterior corneal surface--that is, the "air to endothelium" interface. Through a 5.0 mm scleral incision, a deep stromal pocket was created across the cornea, using the(More)
PURPOSE To report the preliminary results of a surgical technique for transplantation of posterior corneal tissue through a sclerocorneal pocket incision for corneal endothelial disorders. DESIGN Retrospective, noncomparative, interventional cases series. PARTICIPANTS AND INTERVENTION In seven sighted human eyes, a deep stromal pocket was created across(More)
In the aphakic eye, with intact iris diaphragm, silicone oil has frequently caused a pupillary block. In this situation aqueous humour accumulates behind the iris and forces silicone oil through the pupil into the anterior chamber. An iridectomy at the 6 o'clock position can effectively prevent this pupillary block. The iridectomy allows free passage of(More)
PURPOSE The kind and the degree of preferred collagen fibril orientation in normal human corneal stroma were investigated as important qualities of the cornea with respect to its mechanical properties and, hence, to refractive surgery. To determine whether this information is relevant to corneal disease, the authors investigated collagen fibril orientation(More)
PURPOSE Using staining pigments with which we had gained experience in dermatography (medical tattooing) treatments of leucoma corneae, a new approach was developed to create an artificial iris-like staining at the mid-stromal level of the cornea to treat photophobia in a patient with posttraumatic aniridia. METHODS After a central 4-mm half-depth(More)
Since antiquity many attempts were made and hence many methods were devised in order to minimalize the disfiguration and stigmatization caused by leucoma corneae. Dermatography, a refined, modified tattooing technique, was developed to treat this affliction. Materials and method are safe and simple. A number of 12 patients has been treated over a period of(More)
