Purpose: To generate a normative donor topographic database from rasterstereography images of whole globes acquired in an eye-bank setting with minimal manipulation or handling.

Setting: Eye-bank laboratory.

Methods: In a retrospective study, rasterstereography topographic images that had been prospectively collected in duplicate of donor eyes received by the Central Ohio Lions Eye Bank between 1997 and 1999 were analyzed.

Purpose: Creutzfeldt-Jakob disease (CJD) transmission has been documented to occur from the use of corneal grafts. We report 4 cases of CJD with a history of corneal transplantation and assess the frequency of coincidental CJD among corneal transplant recipients.

Methods: Medical records and eye bank documents were reviewed.

Purpose: To develop an index for the detection of keratoconic patterns in corneal topography maps from multiple devices.

Methods: For development, an existing Keratron (EyeQuip) topographic dataset, consisting of 78 scans from the right eyes of 78 healthy subjects and 25 scans from the right eyes of 25 subjects with clinically diagnosed keratoconus, was retrospectively analyzed. The Cone Location and Magnitude Index (CLMI) was calculated on the available axial and tangential curvature data.

Purpose: To compare optical quality, visual function, corneal shape, ocular wavefront aberrations, and patient-reported symptoms and satisfaction after laser in situ keratomileusis (LASIK) with two different excimer lasers.

Design: Prospective randomized clinical trial.

Methods: In an institutional practice setting, 60 eyes of 30 patients with low to moderate myopia were randomized to receive LASIK in one eye with the Technolas 217A; the other eye was treated with the VISX S3.
