What is DMEK used for?
DMEK is the most advanced form of partial corneal transplant procedure indicated in diseases affecting the innermost, endothelial layer of the cornea. In DMEK surgery, only a single thin layer of cells is replaced, allowing for an exact anatomical replacement of the damaged cells.
What is the success rate of DMEK surgery?
“We found that DMEK and DSEK had similarly favorable 5-year survival rates (93%) when performed by experienced surgeons for the leading indication, Fuchs’ endothelial corneal dystrophy.
How thick is DMEK tissue?
Only 10-15 microns thick, DMEK’s thinner graft creates less risk of tissue rejection, quicker recovery and the potential for superior vision than can be achieved with DSEK or full-thickness penetrating keratoplasty.
How is DMEK done?
DMEK is a partial-thickness cornea transplant procedure that involves selective removal of the patient’s Descemet membrane and endothelium, followed by transplantation of donor corneal endothelium and Descemet membrane without additional stromal tissue from the donor. The graft tissue is merely 10-15 microns thick.
What is the difference between DMEK and DSEK?
Both DMEK and DSAEK remove Descemet’s membrane and endothelium. DMEK adds only a new Descemet’s membrane and endothelium. DSAEK also adds a new Descemet’s membrane and endothelium but with a layer of donor stroma.
How long does gas bubble last after DMEK?
As the gas bubble dissipates over seven to ten days, vision continues to improve. When there are no other eye problems, DMEK can result in 20/20 vision within a few months after treatment.
Is DMEK surgery painful?
Some irritation, grittiness or aching of the eye is normal after DMEK/DSAEK. Severe pain is unusual. The eye can also feel itchy.
Which is better DMEK or Dsaek?
DMEK is more selective than DSAEK. Both DMEK and DSAEK remove Descemet’s membrane and endothelium. DMEK adds only a new Descemet’s membrane and endothelium. DSAEK also adds a new Descemet’s membrane and endothelium but with a layer of donor stroma.
How long does a DMEK procedure last?
Dr. Berger then places healthy corneal tissue (called a donor disc) inside the eye through a small incision and positions it with a precisely-sized air bubble to hold the disc of donor tissue in place. DMEK usually takes about 30 minutes to complete.
Where is Descemet’s membrane?
Small bloodvessels cut across near the margin of the cornea. Descemet’s membrane (or the Descemet membrane) is the basement membrane that lies between the corneal proper substance, also called stroma, and the endothelial layer of the cornea.
How long after DMEK Can you drive?
Patients may be able to resume driving and performing light activities within a week after DMEK surgery. Eighty percent of the healing that needs to occur takes place within the first month after treatment. Full recovery is usually complete within four to six months.
Can I watch TV after corneal transplant?
Contact sports are discouraged after corneal transplant. Otherwise, normal activity can be resumed within a few days. After the first day, shaving, brushing teeth, bathing, light housework, bending over, walking, reading, and watching TV will not hurt the eye.
What is DSAEK and DMEK?
Descemet’s stripping automated endothelial keratoplasty (DSAEK) and Descemet’s membrane endothelial keratoplasty (DMEK) are partial thickness corneal transplants performed to replace the endothelium (the innermost portion of the cornea).
Who’s a good candidate for a DSAEK or DMEK surgery?
Who’s A Good Candidate for a DSAEK or DMEK Surgery? DSAEK and DMEK are best suited for patients with conditions related to the endothelial cells, which include: A full-thickness corneal transplant will still be required for patients with corneal scarring or other conditions such as keratoconus.
What is DSAEK/DMEK (partial thickness corneal transplant) surgery?
What Is DSAEK/DMEK (Partial Thickness Corneal Transplant) Surgery? The cornea is the clear dome at the very front part of the eye and is composed of five main layers. The endothelium is a single layer of cells coating the inside portion of the cornea.
