Article Synopsis
- Some anterior chambers may resist shallowing due to low posterior pressure or deep anatomy, complicating DMEK procedures.
- A hands-free technique using cellulose sponges temporarily added under the eyelid speculum helps increase posterior pressure, making it easier to manage the anterior chamber during surgery.
- This method is effective in bicameral eyes with a vitreous body but is unsuitable for unicameral eyes post-vitrectomy.
Purpose: The aim of this study was to evaluate Descemet membrane endothelial keratoplasty (DMEK) scroll width and length in relation to variable velocities as the tissue transits through wide and narrow lumen glass tubes.
Methods: Sets of DMEK tissue were processed using the Iowa Lions Eye Bank standard DMEK protocol and were passed through 2 glass tube widths at variable speeds. Two hourglass-shaped glass tubes were created, one "wide" and one "narrow.
Purpose: The aims of this study were (1) to compare "front" and "rear" methods for loading Descemet membrane endothelial keratoplasty (DMEK) tissue into both micro-Jones and standard-Jones tubes and (2) to evaluate the efficacy of a cone-shaped glass funnel adapter designed to make loading DMEK tissue safer for corneal endothelial cells.
Methods: The corneal endothelium was stained with 0.06% trypan blue to confirm equivalence between mate corneas.
