BACKGROUND The purpose of this study was to compare differences in visual outcomes, higher-order aberrations, contrast sensitivity, and dry eye in patients undergoing photorefractive keratectomy using wavefront-guided VISX CustomVue™ and wavefront-optimized WaveLight(®) Allegretto platforms. METHODS In this randomized, prospective, single-masked,(More)
PURPOSE To provide a background regarding the biochemical rationale for corneal collagen cross-linking (CXL) and outline its current use, critically evaluate the current literature for the use of CXL in nonectatic disorders, highlight limitations and areas for further research, and address additional novel applications of CXL. METHODS A literature search(More)
BACKGROUND The purpose of this study was to evaluate the American Society of Cataract and Refractive Surgery (ASCRS) intraocular lens (IOL) calculator for eyes with prior radial keratotomy and assess the accuracy of its methods in predicting IOL power in patients with previous radial keratotomy. METHODS This retrospective study included data from 15 eyes(More)
BACKGROUND The purpose of this work is to report our experience using loteprednol 0.5% for routine prophylaxis after photorefractive keratectomy in an academic refractive surgery center. MATERIALS AND METHODS Photorefractive keratectomy was performed on 579 eyes from 316 patients in this retrospective chart review of patients treated postoperatively with(More)
PURPOSE To compare outcomes in visual acuity, refractive error, higher-order aberrations (HOAs), contrast sensitivity, and dry eye in patients undergoing laser in situ keratomileusis (LASIK) using wavefront (WF) guided VISX CustomVue and WF optimized WaveLight Allegretto platforms. METHODS In this randomized, prospective, single-masked, fellow eye study,(More)
PURPOSE To evaluate the indications and outcomes of amniotic membrane transplantation (AMT) performed within the first 2 weeks of presentation in the management of patients with acute Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). METHODS A retrospective chart review from January 1998 to May 2011 identified 128 SJS/TEN patients(More)
Endothelial keratoplasty is evolving with increased attention placed on the optical qualities of the posterior donor lenticule. In efforts to improve visual outcomes, the effects of the thickness, smoothness, and planar profile are being studied. This paper describes a double-pass microkeratome technique to create ultra-thin (less than 100 μm) Descemet's(More)
PURPOSE To assess the regression rate of conductive keratoplasty (CK) in patients with or without previous laser-assisted in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK). SETTING University of Utah, Medical School, John A. Moran Eye Center, Salt Lake City, Utah. MATERIALS AND METHODS A retrospective, age-matched chart review(More)
To evaluate the safety, efficacy, advantages, and limitations of femtosecond laser-assisted cataract surgery through a review of the literature. A PubMed search was conducted using topic-appropriate keywords to screen and select articles. Initial research has shown appropriate safety and efficacy of femtosecond laser-assisted cataract surgery, with(More)
PURPOSE To investigate the function of platelet-activating factor (PAF) in cultured retinal pigment epithelial (RPE) and choroidal endothelial (CE) cells. METHODS The in vitro and in vivo expression of PAF-receptors (PAF-R) on both these cells was determined. The production of PAF by RPE cells was also determined. The effect of PAF on the proliferation,(More)
