Penetrating keratoplasty (PK) has been the gold standard for the surgical treatment of most corneal pathologies; lamellar keratoplasty that only replaces the diseased corneal layers has recently evolved as an alternative, however. Innovations in surgical technique and instrumentation provide visual outcomes comparable to PK. We review the indications and(More)
OBJECTIVE To investigate the magnitude and the possible causes of the refractive changes after Descemet's stripping with automated endothelial keratoplasty (DSAEK). In this article we describe the changes in corneal power after DSAEK and correlate them with the shape, diameter, and thickness of the endothelial graft obtained. STUDY DESIGN Retrospective(More)
PURPOSE To evaluate in a rabbit model the differences in cellular and matrix stromal response in low and high attempted corrections between photorefractive keratectomy (PRK) and laser-assisted subepithelial keratectomy (LASEK). SETTING Louisiana State University Health Sciences Center, Department of Ophthalmology and Neuroscience Center, New Orleans,(More)
OBJECTIVE Telerobotic surgery is a novel technology that can improve a surgeon's manual dexterity as well as the results achieved with microsurgical procedures. METHODS A prototype Robot-Assisted MicroSurgery (RAMS) microdexterity enhancement system developed by the Jet Propulsion Laboratory and MicroDexterity Systems, Inc., was tested in 10 rats. Carotid(More)
PURPOSE To assess ultrastructural modifications in keratocytes and inflammatory cell response in rabbit corneas after riboflavin and ultraviolet A exposure using immunofluorescence microscopy. METHODS Twenty adult New Zealand albino rabbits weighing 2.0–3.0 kg were used in this study. Two rabbits served as controls.The animals had their epithelia removed(More)
PURPOSE To evaluate excimer laser in situ keratomileusis (LASIK) for hyperopia and its predictability. METHODS We performed a retrospective study of 100 eyes that had LASIK for hyperopia to assess predictability and long-term stability of refractive results. The Chiron Automated Corneal Shaper was used to create the flap and the Keracor 117CT(More)
PURPOSE To evaluate endothelial cell survival 2 years after Descemet-stripping automated endothelial keratoplasty (DSAEK) for the treatment of endothelial dysfunction in the presence of an anterior chamber intraocular lens (AC IOL). SETTING LSU Eye Center, New Orleans, Louisiana, and Florida Eye Microsurgical Institute, Boynton Beach, Florida, USA. (More)
PURPOSE To determine whether a novel platelet-activating factor (PAF) antagonist prevents experimentally induced diffuse lamellar keratitis (DLK) after laser in situ keratomileusis (LASIK). SETTINGS Department of Ophthalmology and Neuroscience Center of Excellence, Louisiana State University Health Science Center, New Orleans, Louisiana, USA. METHODS(More)
PURPOSE To evaluate safety, predictability, efficiency, and long-term stability of laser in situ keratomileusis (LASIK) for spherical hyperopia. METHODS This study was a retrospective 5-year analysis of 67 patients (125 eyes) who had LASIK for spherical hyperopia; preoperative mean manifest spherical equivalent refraction was +3.84+/-1.13 D (range +1.00(More)
