Corneal optical prostheses.
Recent advances in the field of plastic optical corneal prostheses suggest that they have finally moved from the experimental to the clinical field. To some extent this feeling is justified because in the past io years many types of keratoprostheses have been used, improving vision in eyes which would otherwise have remained blind. The numerous publications on this subject and the various model...
متن کاملEffects of diabetic keratopathy on corneal optical density, central corneal thickness, and corneal endothelial cell counts
Diabetic keratopathy is an ocular complication that occurs with diabetes. In the present study, the effect of diabetic keratopathy on corneal optical density, central corneal thickness, and corneal endothelial cell count was investigated. One hundred and eighty diabetic patients (360 eyes) were enrolled in the study during the period from March, 2012 to March, 2013. The patients were divided in...
متن کاملFemtosecond optical ranging of corneal incision depth.
Excimer laser ablation has been proposed as a technique for keratorefractive surgery. Clinical acceptance of linear-incision laser keratectomy may depend on the availability of a method for accurately and noninvasively monitoring incision depth during the ablation process. We have developed a femto-second optical ranging technique for measurement of corneal incision depth. This technique uses n...
متن کاملOptical zone diameters for photorefractive corneal surgery.
PURPOSE To examine the physiological optics of photorefractive corneal surgery and to study the effect on glare production of the optical zone diameter. METHODS An optical analysis computer program was used to generate rays that define the edge of the optical zone for any given pupil size and glare-free field. RESULTS The optical zone diameter must be based on the postoperative corneal curv...
متن کاملOptical iridectomy in children with corneal opacities.
BACKGROUND Optical iridectomy creates a clear entrance pupil, improving vision in patients with segmental corneal opacities. An area of clear peripheral cornea can produce retinal images compatible with good visual acuity. MATERIALS AND METHODS The records of 22 children who underwent optical iridectomy from January 2002 to June 2004 were reviewed retrospectively. The optical iridectomy site ...
