We are proud to be the first practice in South and Central Texas to offer DMEK to patients with corneal edema from Fuch’s Dystrophy and other corneal diseases. Previously, patients interested in DMEK surgery would have to travel across the country to find a surgeon experienced in the newest technique in endothelial transplants, but now Texans can visit Drs. Kenneth Maverick and James Lehmann in San Antonio for this latest advancement in corneal transplantation.

What is DMEK? How does it differ from DSEK? Is it really any better?

DMEK stands for Descemet’s Membrane Endothelial Keratoplasty and involves precise anatomic replacement of the diseased part of the cornea. Over the last decade, DSEK has emerged as a significant advancement in corneal transplantation, and it is now performed more frequently than traditional transplants; however

in DSEK, the surgeon adds tissue to the recipient’s cornea, and while it is superior to a full-thickness transplant, there are some shortcomings.

Typically DSEK patients do not reach 20/20 vision, they have a shift in their glasses prescription, and require frequent drops to prevent rejection. The rate of rejection is better than that in traditional keratoplasty, but it occurs in approximately 10% of patients.

DMEK is the logical evolution of endothelial surgery, with better vision in a shorter recovery time, no change in a patient’s glasses prescription, and a lower rejection rate than DSEK.

We have performed DMEK in patients who have had successful DSEK surgery in their other eye, and every one prefers the vision in the DMEK eye over the DSEK eye, hands down.

If you have Fuch’s Dystrophy (with or without a cataract) and would like to make an appointment with Drs. Maverick and Lehmann, please call our office at 210-614-3600 and ask for Michelle Arevalos. Also, you can contact her at arevalos@focalpointvision.com.
