Abstract Details



Purpose:

To evaluate the incidence of secondary cataract after Descemet membrane endothelial keratoplasty (DMEK), the feasibility and the outcome of phacoemulsification after DMEK.

Setting:

Retrospective study

Methods:

From a series of 106 consecutive phakic eyes that underwent DMEK for Fuchs endothelial dystrophy or bullous keratopathy, five (4.7%) required cataract surgery 9.2 (±3.8) months (range 4 to 14 months) after the initial DMEK. Outcomes after phacoemulsification were retrospectively assessed by reviewing the change in visual acuity, refractive error, endothelial cell density, pachymetry and the incidence of complications.

Results:

All phacoemulsification surgeries were uneventful and no dislocations and/or detachments of the Descemet graft were observed. At 6 to 12 months after phacoemulsification, all eyes reached a BCVA of ?20/30 (0.6) and were within 0.5D of the intraocular lens power calculations. Endothelial cell density decreased from on average 1535 (±195) cells/mm2 before, to 1158 (±250) cells/mm2. No significant changes in pachymetry values were observed up to 6 to 12 months postoperatively. All corneas remained clear throughout the study period.

Conclusions:

Phacoemulsification after DMEK can be performed with minimal risk of graft dislocation and may provide good refractive and visual outcomes with an acceptable decrease in endothelial cell density.
