Refractive, topographic, and visual outcomes of same-day corneal cross-linking with Ferrara intracorneal ring segments in patients with progressive keratoconus.

Purpose: To report refractive, topographic, and visual outcomes 12 months after same-day treatment with corneal cross-linking (CXL) and Ferrara intracorneal ring segments (ICRS) in eyes with progressive keratoconus (KC) and contact lens intolerance.

Methods: This was a case series of 7 eyes (7 patients) with progressive mild to moderate keratoconus and contact lens intolerance undergoing implantation of Ferrara ICRS immediately followed by corneal cross-linking. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refractive error, pachymetry, and keratometry were evaluated at 3, 6, and 12 months of follow-up.

Endothelial cell decay after descemet's stripping automated endothelial keratoplasty and top hat penetrating keratoplasty.

Purpose: To analyze endothelial cell density (ECD) decay after Descemet's stripping automated endothelial keratoplasty (DSAEK) and top hat keratoplasty (THPK) in patients with Fuchs' endothelial dystrophy (FED) and/or pseudophakic bullous keratopathy (PPBK).

Methods: Patients underwent either THPK (n = 33) or DSAEK (n = 39) at the Erasmus Medical Center, Rotterdam. For each nonrandomized cohort, a biexponential regression model for ECD decay was fitted.

[The IC3D classification of the corneal dystrophies].

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 have a genetic basis.

Long-term follow-up of hydrogel intracorneal lenses in 2 aphakic eyes.

We report the outcome of hydrogel intracorneal lens implantation in 2 patients. The lenses were implanted at approximately 50% depth in the cornea to correct high hyperopic refractive errors of 10.5 diopters (D) and 14.
