What is the difference between DSEK and DMEK?

What is the difference between DSEK and DMEK?

DSAEK is the automated version of this procedure, which uses a machine to cut tissue. DMEK, on the other hand, uses extremely thin donor tissue, with a better chance of restoring good vision to the patient.

What is DSEK in ophthalmology?

DSEK is a corneal transplant technique where the unhealthy, diseased, posterior portion of a patient’s cornea is removed and replaced with healthy donor tissue obtained from the eye bank. Unlike the PK, the DSEK procedure utilizes a much smaller surgical incision and requires no corneal sutures.

How long is recovery from DMEK surgery?

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.

What is the recovery time for DMEK surgery?

How long do you lay flat after cornea transplant?

You will be required to lie flat on your back, facing the ceiling for one hour immediately after the operation to help the bubble help the tissue to adhere.

Which is better for vision DMEK or DSAEK?

DMEK provides better vision. Large series demonstrate that visual acuity after DMEK can be 20/25 or better 75 percent of the time, while visual acuity after DSAEK will be limited to 20/30 or worse 75 percent of the time. DMEK not only provides better vision, but better vision faster, with best vision returning sooner than with DSAEK.

Which is better DMEK or cornea transplant?

DMEK and DSEK have a shorter recovery time and less chance of rejection. The endothelium layer is replaced, but the other layers of the cornea are left untouched. These procedures take less time to complete, have less risk, and have shorter recovery times and better vision than full thickness cornea transplant.

Which is better DMEK or DSAEK for fuchs’dystrophy?

Both are procedures to restore vision in an eye with Fuchs’ dystrophy. DMEK, or Descemet’s Membrane Endothelial Keratoplasty, is a procedure in which defective pump (endothelial) cells in the cornea are replaced strictly with healthy pump cells from a donor cornea.

Who is the first doctor to do DMEK and DSAEK?

John Parker was one of the first ophthalmologists in the U.S., and the first in the region, to perform both DSAEK and DMEK surgery. Dr. Parker has offered DSAEK since 2004 and DMEK since 2011, and has performed both procedures hundreds of times.
