Abstract Details

Purpose:

To evaluate the clinical outcome up to two years after Descemet membrane endothelial keratoplasty (DMEK) for the first 500 consecutive cases.

Setting:

Netherlands Institute for Innovative Ocular Surgery / Tertiary referral center.

Methods:

In 500 eyes of 393 patients who underwent DMEK at a tertiary referral center for Fuchs endothelial dystrophy, bullous keratopathy or previous corneal transplant failure, best corrected visual acuity (BCVA), endothelial cell density (ECD), pachymetry and postoperative complications were evaluated before, and 6, 12 and 24 months after DMEK

Results:

At 2 years follow-up, 82% of eyes reached a BCVA of ≥20/25 (≥0.8), 52% ≥20/20 (≥1.0) and 16% ≥20/18 (≥1.2) (n=360). Mean ECD decreased to 1600 cells/mm2 (n=447), 1530 cells/mm2 (n=427), and 1400 cells/mm2 (n=392) at 6, 12 and 24 months, respectively, corresponding to a decrease of 37%, 40%, and 45%, respectively, compared to preoperative ECD. Postoperative pachymetry averaged 525 µm at 6 months and remained stable up to 2 years. 32 eyes (6.4%) required re-transplantation within the first 2 years. Main longer term complications were secondary graft failure and allograft rejection.

Conclusions:

BCVA outcomes after DMEK are excellent up to 2 years, while ECD decrease resembles those of other keratoplasty techniques. With the low longer term complication rate, DMEK may become the first choice of treatment in corneal endothelial disease.
