Brief Summary

Descemet's stripping automated endothelial keratoplasty (DSAEK) and Descemet's membrane endothelial keratoplasty (DMEK) are becoming increasingly popular as treatments for Fuchs' endothelial dystrophy. However, despite several years of use the incidence of cystoid macular edema and damage related to increased intraocular pressure (IOP), and the forward scattering of light through the eye following DSAEK or DMEK have to our knowledge not been prospectively described. Therefore, this project will be a randomized controlled trial investigating these matters.

Outcome Measures

Primary Outcomes (1)

  • Best corrected visual acuity (BCVA)

    BCVA will be measured using the early treatment diabetic retinopathy study (ETDRS) chart.

    12 months

Secondary Outcomes (7)

  • Cystoid macular edema

    3 months

  • Largest pupil diameter (mm)

    12 months

  • Iris contraction velocity (mm/s)

    12 months

  • Circumpapillary Retinal Nerve Fibre Layer Thickness (cpRNFLT) (µm)

    12 months

  • Contrast-sensitivity (Weber contrast units)

    12 months

  • +2 more secondary outcomes

Other Outcomes (1)

  • Epiretinal membrane (ERM) formation

    12 months

Study Arms (2)

Phaco-DSAEK

OTHER

Subjects randomized to this arm will consist of patients with both Fuchs' endothelial dystrophy and cataract. These will be treated with phacoemulsification and Descemet's stripping automated endothelial keratoplasty.

Procedure: Phaco-DSAEK

Phaco-DMEK

OTHER

Subjects randomized to this arm will consist of patients with both Fuchs' endothelial dystrophy and cataract. These will be treated with phacoemulsification and Descemet's membrane endothelial keratoplasty.

Procedure: Phaco-DMEK

Interventions

Phaco-DSAEKPROCEDURE

The intervention will be performed as a DSAEK triple-procedure with phacoemulsification and intraocular lens implantation prior to DSAEK.

Phaco-DSAEK
Phaco-DMEKPROCEDURE

The intervention will be performed as a DMEK triple-procedure with phacoemulsification and intraocular lens implantation prior to DMEK.

Intervention Model
PARALLEL
Model Details: Study subjects with the requirement for endothelial keratoplasty and a concomitant need for cataract extraction will be randomized 1:1 to either phaco-DSAEK or phaco-DMEK. Further, a third group consisting of sujects with a solely need for cataract extraction will be included as a control group in our study. The three groups will be prospectively followed.
