"Double bubble" deep anterior lamellar keratoplasty for management of corneal stromal pathologies.

'Big Bubble' deep anterior lamellar keratoplasty (DALK) is becoming an accepted corneal transplantation technique for keratoconus and other anterior stromal corneal pathologies that spare the Descemet's membrane (DM) and endothelium. However, it is not always possible to conclusively recognise formation and identification of the 'Big Bubble'. We describe the surgical technique of DALK called 'Double Bubble' technique that allows the surgeon to definitely and immediately identify the formation of an adequate big bubble.

Microbial keratitis after penetrating keratoplasty: impact of sutures.

Purpose: To determine the impact of presence or absence of sutures in cases with post-penetrating keratoplasty (PKP) microbial keratitis.

Design: A 10-year retrospective chart review of post-PKP patients admitted with microbial keratitis at the Royal Victorian Eye and Ear Hospital, Melbourne, between January 1998 and December 2008 was undertaken.
