PDEK: best of both endothelial worlds.
PDEK (Pre-Descemet Endothelial Keratoplasty) transplants the Descemet membrane, endothelium, and a 30-micron pre-Descemet stromal layer (Dua's layer). The result: visual outcomes close to DMEK with surgical handling closer to DSAEK. Useful in young donors, complex eyes, and re-grafts.
Why choose us
International standard. Regional access.
Devers-trained endothelial surgeon
Fellowship at Devers Eye Institute under Prof. Mark A. Terry, a leading center for endothelial keratoplasty research and innovation.
AAO-published in DMEK / DSAEK
Published research on DMEK in eyes with prior refractive surgery. PDEK is the natural extension of that work.
Right donor, right technique
PDEK is especially useful with young donor tissue (where DMEK preparation can fail). We select the technique based on the donor age and your anatomy.
Lower rejection vs PKP
Like DMEK and DSAEK, PDEK only replaces the inner cornea, leaving the front surface intact and lowering rejection risk dramatically vs full-thickness grafts.
Procedures & pricing
Transparent USD pricing.
Final cost is set after clinical examination. Local-currency equivalents available on request. Insurance reports issued for international patients.
| Procedure | Best for | From (USD) |
|---|---|---|
| PDEK (standard) | Endothelial keratoplasty, same price band as DMEK/DSAEK; final quote after examination | $3,000 - $3,500 |
| PDEK + cataract (triple) | Combined with phaco + IOL, total depends on the IOL tier you choose | $3,600 |
