About this study

Official title: Corneal Transplantation by DMEK - is it Really Better Than DSAEK?

The purpose of this study is to determine whether corneal transplantation by Descemet Membrane Endothelial Keratoplasty more favourable and cost-effective is compared to Descemet Stripping Automated Endothelial Keratoplasty for Fuchs Endothelium Corneal Dystrophy.

Read the detailed description

FECD is a progressive, multifactorial and irreversible disease characterized by accelerated loss of corneal endothelial cells in the innermost layer of the cornea that leads to vision impairment and potential blindness if left untreated. FECD is responsible for more than 50% of the 1.300 annual corneal transplantations in the Netherlands.

Corneal transplantation improves vision and quality of life in patients with corneal disease. Currently, the standard of care for patients with Fuchs Endothelial Corneal Dystrophy (FECD) is Descemet Stripping Automated Endothelial Keratoplasty (DSAEK), in which only the posterior layers of the cornea are transplanted. However, visual recovery following DSAEK is suboptimal. Descemet Membrane Endothelial Keratoplasty (DMEK), the latest technique in corneal transplantation involves transplantation of only a monolayer of corneal endothelium and Descemet's membrane providing the thinnest endothelial graft possible. DMEK has been suggested to result in faster and better visual recovery compared to DSAEK. While the economic burden, both medical and social, from this disease has not been assessed to date, costs associated with corneal transplantation reach $ 110 million dollars yearly for the 47.000 transplantations in the USA.

The objective of this project is to assess the effects and costs of DMEK vs. DSAEK in order to determine whether the new technique is effective and cost-effective over the standard technique.

The primary outcome measure is best-corrected visual acuity. Secondary outcome measures are contrast acuity, astigmatism, quality of vision, endothelial cell loss, incidence of graft rejection, primary graft failure, cornea donor loss due to preparation, and generic and vision-related quality of life.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in best-corrected visual acuity

    Visual acuity will be measured by ETDRS letter charts

    Measured: Preoperatively and 3, 6, 12 months post-operatively

Secondary outcomes (10)
  1. Change in contrast sensitivity

    Contrast sensitivity will be measured using the CSV-1000 chart by Vector Vision

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  2. Change in astigmatism

    Astigmatism will be measured using the The Pentacam HR (Oculus Inc., Lynnwood, USA)

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  3. Change in corneal scatter

    Corneal scatter will be measured using a confocal microscope

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  4. Change in endothelial cell loss

    Endothelial cell loss will be measured using specular microscopy photography.

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  5. Incidence of graft rejection

    Measured: 3, 6, 12 months post-operatively

  6. Incidence of primary graft failure

    Primary Graft failure will be assessed during ophthalmic examination.

    Measured: 3, 6, 12 months post-operatively

  7. Incidence of cornea donor loss due to preparation

    The eye bank providing the donor cornea's will register cornea donor loss if a complication occurs during preparation that renders the cornea unusable.

    Measured: Preoperatively

  8. Change in generic quality of life

    Generic quality of life will be measured using the HUI3 (Health Utility Index Mark 3), which test 8 dimensions: vision, hearing, speech, ambulation, dexterity, emotion, cognition and pain.

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  9. Change in generic quality of life

    Generic quality of life will be measured using the EQ-5D-5L questionnaire, which tests 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.

    Measured: Preoperatively and 3, 6, 12 months post-operatively

  10. Change in vision-related quality of life

    Vision-related quality of life will be measured using the National Eye Institute Visual Function Questionnaire (NEI VFQ-25), which is specified for vision-related quality of life.

    Measured: Preoperatively and 3, 6, 12 months post-operatively

Questions about this trial

What is this clinical trial studying?

A study testing DMEK and DSAEK in people with Fuchs' Endothelial Dystrophy, run by Maastricht University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in best-corrected visual acuity (time frame: Preoperatively and 3, 6, 12 months post-operatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02793310, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2019.
