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 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)
PURPOSE To report low complication rates in Descemet membrane endothelial keratoplasty (DMEK) using sulfur hexafluoride (SF6) gas, a novel glass injector, and donor tissue prestripped by an eye bank technician. METHODS A standardized technique of DMEK was performed in 80 consecutive Fuchs corneal dystrophy cases using technician-prestripped tissue, a(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)
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)
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)
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)
PURPOSE To present 6-month clinical outcomes from a series of 165 consecutive Descemet membrane endothelial keratoplasty (DMEK) procedures before and after the introduction of a novel stromal-sided S-stamp preparation technique that has decreased the incidence of iatrogenic primary graft failure by eliminating upside-down grafts. DESIGN Retrospective(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 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)
