Tissue quality of eye-bank-prepared precut corneas for Descemet's stripping automated endothelial keratoplasty.

Objective: To evaluate endothelial cell density (ECD) of eye-bank-prepared tissue for use in Descemet's stripping automated endothelial keratoplasty (DSAEK).

Design: Prospective case series of consecutive corneal tissue prepared for DSAEK surgery.

Participants: Sixty-seven sequential corneal-scleral tissue specimens representing 48 human donors processed for use in DSAEK surgery by the Regional Tissue Bank (Halifax, Nova Scotia).

Keratoconus caused by eye rubbing in patients with Tourette Syndrome.

Objective: To report the association between keratoconus and Tourette Syndrome (TS) and to reinforce that eye rubbing may be a causative factor for keratoconus.

Design: Observational case series.

Participants: Three patients with TS who presented with clinical and topographic findings suggestive of asymmetric or unilateral keratoconus.

Femtosecond laser-assisted mushroom configuration deep anterior lamellar keratoplasty.

Purpose: To review patient outcomes after femtosecond laser-assisted mushroom configuration deep anterior lamellar keratoplasty.

Methods: Seven eyes of seven patients with a mean age of 30 years underwent femtosecond laser-assisted mushroom configuration deep anterior lamellar keratoplasty from April 2008 to September 2008. Patients had keratoconus, corneal ectasia or scarring.
