purpose: to evaluate the visual and refractive outcomes of automated lamellar therapeutic keratoplasty (altk) in patients with keratoconus. methods: in this prospective noncomparative clinical trial, altk was performed in 14 eyes of 14 patients with moderate to severe keratoconus. all patients were spectacle and contact lens intolerant.  uncorrected visual acuity (ucva), best corrected visual a...

THE USE of a Barron artificial anterior chamber (Katena Products, Inc) results in safer and more efficient surgery for deep lamellar endothelial keratoplasty (DLEK) procedures, according to Pavel Studeny MD. Speaking to delegates at the first Cornea Day organised as part of the 10th ESCRS Winter Refractive meeting, Dr Studeny said that the Barron device successfully addresses some of the proble...

PURPOSE To describe a novel technique of using Spectral-domain (SD) anterior segment optical coherence tomography (SD-OCT) in the evaluation of corneal epithelial healing under a therapeutic contact lens (TCL) after lamellar keratoplasty and Epi-LASIK procedures. DESIGN Prospective, non-comparative, observational case series. METHODS Ten eyes of eight patients undergoing lamellar corneal tr...

Objective. To evaluate the therapeutic effect of big bubble deep anterior lamellar keratoplasty (DALK) in patients with deep fungal keratitis. Methods.Consecutive patients who had DALK for deep fungal keratitis at Shandong Eye Hospital between July 2011 and December 2012 were included. In all patients, the infiltration depth was more than 4/5ths of the corneal thickness. DALK surgery was perfor...

Conventional corneal transplantation, in the form of penetrating keratoplasty (PK), involves full-thickness replacement of the cornea, and is a highly successful procedure. However, the cornea is anatomically a multi-layered structure. Pathology may only affect individual layers of the cornea, hence selective lamellar surgical replacement of only the diseased corneal layers whilst retaining una...
