in addition to graft clarity, an acceptable refractive error is essential to consider a corneal transplant successful. the most common complication of penetrating keratoplasty (pk) is postkeratoplasty astigmatism which can result in decreased visual acuity, anisometropia, and mono-ocular diplopia. these complications can cause patient dissatisfaction, in spite of a successful transplant. intrao...

Purpose: To report 2 cases that underwent deep anterior lamellar keratoplasty (DALK) and developed visually significant cataract and subsequently underwent femtosecond laser assisted cataract surgery (FLACS). Methods: Both patients underwent FLACS with implantation of toric intraocular lens (IOL) for correction of postkeratoplasty astigmatism. Capsulorrhexis was performed with the femtosecond l...

PURPOSE Videokeratography is a powerful tool for the diagnosis of corneal shape abnormalities. However, interpretation of the topographic map is sometimes difficult, especially when pathologies with similar topographic patterns are suspected. The neural networks model, an artificial intelligence approach, was applied for automated pattern interpretation in corneal topography, and its usefulness...

Human donor corneas were used for penetrating keratoplasty in one eye of each of 12 rhesus monkeys. In six animals, a 9.5-mm cornea was sutured into a 9.0-mm recipient bed by means of interrupted 10-0 nylon sutures. Six other animals received a 6.5-mm cornea in a 6.0-mm bed. Biomicroscopy, pachymetry, and specular microscopy revealed two distinct healing patterns. Of the six eyes receiving the ...

Astigmatism terminology and source references The article by Trivizki et al. used vector analysis in the understanding of correction of postkeratoplasty astigmatism. The article was effective in examining a complex subject of interest; however, there are problems of terminology and attribution of the source references used for the vectorial analysis. The term correction ratio in the title and o...

PURPOSE The aim of this study was to evaluate both the indications for and results of fitting the Jupiter Scleral Lens in patients with corneal abnormalities. METHOD This was a retrospective case review of 63 patients (107 eyes) fitted with scleral lenses between October 2009 and March 2011 at the UC Davis Eye Center. RESULTS Sixty-three percent of 107 eyes were in patients with keratoconus...

Acinetobacter baumannii is most often responsible for hospital-acquired infections and is occasionally associated with community-acquired infections. We report two cases of A. baumannii endophthalmitis, one with endogenous endophthalmitis and the other with postkeratoplasty endophthalmitis. Although endophthalmitis is rare, ophthalmologists should be alert to the possibility of patients having ...

UNLABELLED ABSTRACT Purpose: To describe change in corneal astigmatism in infants and children of a Native American tribe with a high prevalence of astigmatism. METHODS Longitudinal measurements of corneal astigmatism were obtained in 960 Tohono O'odham children aged 6 months to <8 years. Change in corneal astigmatism (magnitude (clinical notation), J0, J45) across age in children with high a...
