PURPOSE To compare results of the first 100 eyes of Descemet stripping automated endothelial keratoplasty (DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) that were performed with a standardized technique at a single institution. DESIGN Single-center, retrospective case series. PARTICIPANTS The first 100 eyes of standardized DSAEK and DMEK(More)
OBJECTIVE To compare wavefront (WF)-guided and WF-optimized LASIK in myopes. DESIGN Prospective, randomized, eye-to-eye study. PARTICIPANTS A total of 72 eyes of 36 participants with myopia with or without astigmatism. METHODS Participants were randomized to receive WF-guided or WF-optimized LASIK with the WaveLight Allegretto Eye-Q 400-Hz excimer(More)
For physicians to provide appropriate healthcare at a reasonable cost, health reform may not be enough. This essay discusses the scope of educational reform needed in the U.S. to train tomorrow's physicians to practice effectively in an increasingly complicated health care arena. We undertook a review and synthesis of five critiques of medical practice in(More)
BACKGROUND To compare wavefront (WF)-guided and WF-optimized laser in situ keratomileusis (LASIK) in hyperopes with respect to the parameters of safety, efficacy, predictability, refractive error, uncorrected distance visual acuity, corrected distance visual acuity, contrast sensitivity, and higher order aberrations. METHODS Twenty-two eyes of eleven(More)
PURPOSE To compare corneal sensation and self-reported dry eye symptoms after femtosecond-assisted LASIK with conventional versus inverted side cuts. DESIGN Prospective, randomized, eye-to-eye study. PARTICIPANTS A total of 120 eyes in 60 participants with myopia. METHODS Fellow eyes were randomized to receive femtosecond-assisted LASIK with a(More)
We present a review of keratorefractive and intraocular approaches to managing residual astigmatic and spherical refractive error after cataract surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), arcuate keratotomy, intraocular lens (IOL) exchange, piggyback IOLs, and light-adjustable IOLs. Currently available(More)
PURPOSE To assess the long-term clinical course of dry eye in patients with chronic graft-versus-host disease (cGVHD). METHODS A prospective case series of 49 patients with cGVHD was conducted. Complete history and ophthalmic examination were performed at baseline and at 36 months (range, 26-53). All patients received treatment for dry eye. RESULTS Of(More)
PURPOSE To assess the relationship between intraoperative unscrolling time of the donor Descemet membrane endothelial keratoplasty (DMEK) tissue and 6-month postoperative endothelial cell loss (ECL), and to determine whether donor age, scroll tightness, and the presence of an S stamp are related to unscrolling time. METHODS Ninety-three consecutive(More)
PURPOSE To report endothelial cell loss (ECL) caused by a novel S-stamp preparation technique for Descemet membrane endothelial keratoplasty (DMEK). METHODS Six cadaveric human corneas were prepared for DMEK transplantation using a single standardized technique, including the application of a dry ink gentian violet S-stamp to the stromal side of Descemet(More)
PURPOSE To determine the prevalence of gonioscopically narrow anterior chamber angles in a Filipino-American clinic population. PATIENTS AND METHODS The records of 122 consecutive, new, self-declared Filipino-American patients examined in a comprehensive ophthalmology clinic in Vallejo, California were reviewed retrospectively. After exclusion, 222 eyes(More)
