Research Publications


RMLEB leadership and staff participate in ongoing research and publications that advance scientific knowledge and clinical practice to help others overcome blindness. Below are some of the recent publications.

  • Comparison of the Modified Jones Tube Technique and the DMEK EndoGlide Technique With and Without Viscoelastic Material for DMEK Tissue Preparation
    Cornea, 2022
    Purpose: The aim of this study was to compare endothelial cell loss for DMEK (Descemet membrane endothelial keratoplasty) tissue preparation techniques using the modified Jones tube and the DMEK EndoGlide with and without viscoelastic material to protect the endothelium.

  • Alcohol Abuse is Associated with Alterations in Endothelial Cell Morphology
    Cornea, 2022
    Purpose: Alcohol consumption is highly prevalent throughout the world. We sought to detect, in a large sample of cornea donors, whether alcohol abuse is associated with changes in corneal endothelial morphology after accounting for other comorbidities including tobacco use.

  • Viability of Preloaded Descemet Membrane Endothelial Keratoplasty Grafts with 96-hour Shipment
    BMJ, 2021
    Objective: To assess feasibility and compare the effects of 96-hour shipment of Descemet membrane endothelial keratoplasty (DMEK) grafts as a scroll or a tri-fold on cell viability.

  • Comparison of Tri-folded and Scroll-based Graft Viability in Preloaded Descemet Membrane Endothelial Keratoplasty
    Cornea, 2019
    Purpose: To compare corneal endothelial damage associated with 2 techniques for preloaded Descemet membrane endothelial keratoplasty (DMEK): a tri-folded graft stored in a plastic cartridge designed for DMEK and a scrolled graft stored in a modified Jones Tube, at the time of preparation and after shipping.

  • Viability of Descemet Membrane Endothelial Keratoplasty Grafts Folded in the Eye Bank
    Cornea, 2018
    Purpose: Preloaded, trifolded grafts in Descemet membrane endothelial keratoplasty require transfer of the trifolding process from the corneal transplant surgeon to the eye bank technician. We sought to assess whether trifolding may be safely conducted by an eye bank technician with cell loss comparable to standard peeling and lifting.

  • Residual Ethanol Content of Donor Sclera After Storage in 95% Ethanol and Saline Rinse of Various Durations
    American Journal of Ophthalmology, 1999
    Purpose: Some surgeons are wary of using alcohol-preserved sclera for allografts because they fear a toxic effect on surrounding tissue after placement. We set out to determine the amount of ethanol remaining in scleral allograft material after storage in 95% ethanol.
