About this study

The goal of this study is to determine optical and visual function through 5 years after Descemet membrane endothelial keratoplasty (DMEK). The study will also determine graft health (corneal endothelial cell loss) and survival through 5 years after DMEK, and factors associated with these outcomes, as well as assess the relationship between optical and anatomical corneal rehabilitation after DMEK.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Exclusion Criteria

  • Uncontrolled glaucoma or prior filtering surgery (tube shunt or trabeculectomy).
  • Uncontrolled uveitis.
  • High graft failure risk including herpetic keratouveitis or any condition with two or more quadrants of stromal neovascularization.
  • Presence of anterior chamber intraocular lens.
  • Pregnancy
