Abstract Details

Purpose:

To compare the safety and efficacy profiles of DMEK an PDEK in Fuchs´endothelial dystrophy and bullous keratopathy.

Setting:

Department of Ophthalmology, University Hospital Kralovske Vinohrady, Prague, Czech Republic

Methods:

This is a retrospective review of 99 eyes of 93 patients with Fuchs‘ endothelial dystrophy or bullous keratopathy that underwent endothelial keratoplasty performed by one surgeon. 65 eyes (65,7 %) undewent PDEK and 34 eyes (34,3 %) underwent DMEK surgery. 57 eyes (57,6 %) underwent combined procedure - endothelial keratoplasty and phacoemulsification with implantation of monofocal IOL. Postoperative complications were recorded. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), rebbubling rates and endothelial cell density (ECD) were evaluated.

Results:

After six months the mean postoperative CDVA in PDEK group was 0,6 ± 0,2, in DMEK group was 0,7 ± 0,2. Rebubbling procedure was needed in case of 33 eyes (50,8 %) in PDEK group and 7 eyes (20,6 %) in DMEK group. ECD decreased in PDEK group from preoperatively 2948 cells/mm2 on avarage by 49,4 % and in DMEK group from preoperatively 2995 cells/mm2 by 41,2 % after 6 months following the operation. There was one intraoperative complication due to the mature cataract in DMEK group. The anterior vitrectomy with IOL implantation into ciliary sulcus was done.

Conclusions:

The DMEK group showed better postoperative results regarding CDVA and graft related issues. However, a larger set of DMEK patients and longer follow-up are required to interpret these results more precisely.
