We compared experimental wave aberrations in pseudophakic eyes with aspheric intraocular lenses (IOLs) to simulate aberrations from numerical ray tracing on customized computer eye models using corneal topography, angle lambda, ocular biometry, IOL geometry, and IOL tilt and decentration measured on the same eyes. We found high correlations between real and simulated aberrations even for the ey...

PURPOSE To evaluate the expression of inflammatory cytokines and matrix metalloproteinases in the corneal epithelium in pseudophakic corneal edema (PCE). METHODS Tissue sections were prepared from formalin-fixed, paraffin-embedded blocks of corneal buttons removed from 20 patients with PCE during penetrating keratoplasty (PKP) and from 11 age-matched control eyes enucleated because of uveal m...

OBJECTIVE To review 30 years' clinical experience with Fuchs corneal endothelial dystrophy leading to penetrating keratoplasty (PK). METHODS We reviewed the clinical records of patients diagnosed histopathologically as having Fuchs corneal endothelial dystrophy who underwent PK at Duke University Medical Center between January 1, 1972, and December 31, 2001. This observational case series inc...

BACKGROUND To present a method, alternative to penetrating keratoplasty, for the restoration of impaired corneal clarity with anterior stromal scarring following long-standing corneal graft failure. CASE PRESENTATION A 48-year old female who had previously underwent Descemet stripping automated endothelial keratoplasty (DSAEK) for the treatment of pseudophakic bullous keratopathy, presented w...

Pseudophakic cystoid macular edema (PCME) is the most common complication following cataract surgery. In 1-3% of cases it is associated with a decrease in visual acuity. However, PCME has a good prognosis, persisting in only 10% of the patients beyond 2 years. The prophylactic therapy of eyes without additional disease with non-steroidal antiphlogistic drugs or steroids does not influence the f...

PURPOSE To evaluate histological changes in the corneal stroma in pseudophakic bullous keratopathy. METHODS Twenty-eight patients (28 eyes) with pseudophakic bullous keratopathy underwent therapeutic penetrating keratoplasty at Shandong Eye Institute between January 2006 and November 2011. The patients were divided into two groups according to the duration of bullous keratopathy (<1.0 year gr...

PURPOSE The aim of this study was to describe the aims, methods, donor and recipient cohort characteristics, and potential impact of the Cornea Preservation Time Study (CPTS). METHODS The CPTS is a randomized clinical trial conducted at 40 clinical sites (70 surgeons) designed to assess the effect of donor cornea preservation time (PT) on graft survival 3 years after Descemet stripping automa...

Endothelial cell dysfunction as in Fuchs dystrophy or pseudophakic bullous keratopathy, and the limited regenerative capacity of human corneal endothelial cells (HCECs), drive the need for corneal transplant. In response to limited donor corneal availability, significant effort has been directed towards cell therapy as an alternative to surgery. Stimulation of endogenous progenitors, or transpl...

PURPOSE Corneal edema is a significant component of the various forms of herpes simplex virus type 1 (HSV-1)-induced stromal disease. Maintenance of corneal thickness, a reflection of corneal hydration, depends on a physical barrier formed by endothelial cell-cell junctions and by the activity of Na+/K(+)-ATPase pumps that regulate ion flux and thus influence water movement through this cell la...
