PURPOSE To evaluate patient characteristics, indications, and outcomes of pediatric keratoplasty, and to identify variables that may help predict poor surgical outcomes. METHODS The authors performed a retrospective chart review of penetrating keratoplasty performed in children 14 years and younger between 1991 and 2006. Primary keratoplasty data were(More)
BACKGROUND The recent availability of genetic analyses has demonstrated the shortcomings of the current phenotypic method of corneal dystrophy classification. Abnormalities in different genes can cause a single phenotype, whereas different defects in a single gene can cause different phenotypes. Some disorders termed corneal dystrophies do not appear to(More)
PURPOSE To evaluate retention of visual acuity and development of complications after Boston type 1 keratoprosthesis implantation over a longer follow-up period than previously reported. DESIGN Cohort study. PARTICIPANTS Forty eyes of 35 patients who underwent Boston type 1 keratoprosthesis surgery at the University of California, Davis, between 2004(More)
The range of contact lens modalities currently available for the successful optical correction of keratoconus is greatly expanded. We review lens types currently available for the nonsurgical management of keratoconus, including rigid gas-permeable (GP) lenses, intralimbal lenses, corneoscleral lenses, scleral lenses, hybrid lenses, and piggyback lenses. In(More)
OBJECTIVE To describe an outbreak of mycobacterial keratitis after laser in situ keratomileusis (LASIK), including the microbiologic investigation, clinical findings, treatment response, and outcome. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Patients (n = 10) who underwent LASIK surgery between August 22 and(More)
PURPOSE The aim of this study was to assess the effect of donor and recipient factors on corneal allograft rejection and evaluate whether a rejection event was associated with graft failure. METHODS One thousand ninety subjects undergoing penetrating keratoplasty for a moderate risk condition (principally Fuchs dystrophy or pseudophakic corneal edema)(More)
PURPOSE To compare the University of California Davis experience using the Boston keratoprosthesis with the Boston Keratoprosthesis Study Group's initial report. DESIGN Retrospective chart review. PARTICIPANTS We analyzed 30 eyes of 28 patients who previously underwent Boston type 1 keratoprosthesis surgery at our institution between 2004 and 2008. (More)
PURPOSE To determine a possible relationship between donor epithelial status on the first postoperative day after keratoplasty and the eventual health of the corneal surface. METHODS We analyzed 91 patients who underwent penetrating corneal transplantation between January 1998 and January 2000, monitoring the epithelial status of the corneas with(More)
Trabeculectomy is increasingly being performed earlier in the treatment of primary open-angle glaucoma (POAG). Surgically-induced alterations in corneal curvature resulting from filtering surgery may have a significant impact on patients, especially younger ones, whose vision may already be compromised by visual-field loss. Using data obtained by(More)
