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)
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)
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)
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)
A 41-year-old patient with severe anterior segment ectasia and a previous history of failed corneal graft was treated by placing a 14-mm tectonic corneoscleral allograft in the eye to support both the corneal and the scleral thinning. Nylon 10-0 interrupted sutures were used at the sclero-scleral junction. The host conjunctiva, including the limbal area,(More)
PURPOSE Post-laser in situ keratomileusis (LASIK) corneal ectasia is a progressive deformation of the gross corneal anatomy that occurs after surgery. However, this is a rare event even after deep lamellar keratoplasty. We hypothesize that the strength of the lamellar keratoplasty wound is derived from the sutures that enhance the wound edge healing(More)
PURPOSE To report 4 cases of Descemet stripping automated endothelial keratoplasty (DSAEK) in the presence of previous glaucoma filtering surgery. DESIGN Observational case series. METHODS Review of clinical data of 4 patients who underwent DSAEK successfully performed in the presence of previous glaucoma filtering surgery with endothelial survival(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)
BACKGROUND We report a case series of three patients who developed scleral melting 18-26 months after pterygium removal with beta-irradiation that refused to use any donor tissue. CASE SERIES All patients presented with constant pain, redness and foreign body sensation on their eye. RESULTS Initial evaluation revealed the presence of an area of scleral(More)
PURPOSE To evaluate the donor endothelial cell loss in the first year after Descemet stripping endothelial keratoplasy (DSAEK) for the treatment of endothelial dysfunction in the presence of an anterior chamber (AC) intraocular lens (IOL). METHODS We performed a retrospective study of a surgical case series of 25 patients who underwent DSAEK in the(More)
