Corneal allogenic intrastromal ring segments have been described by Jacob and colleagues for the treatment of keratoconus.

Recently, Descemet’s membrane endothelial keratoplasty has emerged as the preferred treatment for corneal endothelial dysfunction because it affords the best visual acuity with the lowest risk for various complications.

Office-based surgery exploded into the popular consciousness with the publication of the 2015 Kaiser study, reporting more than 21,000 cataract operations performed safely and effectively in clinic minor procedure rooms.

S- or F-stamping donor tissue for Descemet’s membrane endothelial keratoplasty is widely practiced to guard against DMEK’s most embarrassing potential complication: accidental upside-down graft implantation.

Corneal allogenic intrastromal ring segments have been described for the treatment of keratoconus.

When starting with Descemet’s membrane endothelial keratoplasty, it is common to manually mark a ring of purple dots on the corneal surface to serve as a centering guide for the graft’s final position.

Following Descemet’s membrane endothelial keratoplasty, retained remnants of host Descemet’s membrane may interfere with graft attachment and compromise the optical quality of the transplanted cornea.

Ultrasert is the name of Alcon’s delivery system for its preloaded AcrySof IQ IOLs. These lenses arrive already packaged inside their injector and need only priming with viscoelastic before delivery.
