Eyes with primary DMEK only and comparable preoperative corrected distance visual acuity (CDVA) served as control. Main outcome parameter was CDVA. Secondary outcome measures were central corneal thickness (CCT), endothelial cell density, and rebubbling rate (RR).Results: The average time interval (+-SD) between primary and secondary DMEK was 12.5+-6 months. Preoperative CDVA (logMAR) was 1.97+-0.90 in the repeat DMEK group and 1.38+-0.92 in the primary DMEK group. At 6 months, both groups showed significant improvement in visual acuity (repeat DMEK group, 0.49+-0.35, P<0.01 and primary DMEK group, 0.40+-0.36, P<0.01). CDVA did not differ significantly between both groups at all time points examined (1, 3, and 6 months postoperatively). Mean CCT values at 3 and 6 months postoperatively did not differ significantly between the two groups (P>0.05). The RR was23% (n=3) in both groups.Conclusion: Repeat DMEK is a useful therapeutic approach in the setting of corneal decompensation following primary DMEK. Functional results of repeat DMEK, visual acuity in particular, are comparable to patients with single DMEK only. Keywords: DMEK, repeat DMEK, corneal edema, corneal transplantation | ||

At 6 months, both groups showed significant improvement in visual acuity (repeat DMEK group, 0.49+-0.35, P<0.01 and primary DMEK group, 0.40+-0.36, P<0.01). CDVA did not differ significantly between both groups at all time points examined (1, 3, and 6 months postoperatively). Mean CCT values at 3 and 6 months postoperatively did not differ significantly between the two groups (P>0.05). The RR was23% (n=3) in both groups.Conclusion: Repeat DMEK is a useful therapeutic approach in the setting of corneal decompensation following primary DMEK. Functional results of repeat DMEK, visual acuity in particular, are comparable to patients with single DMEK only.

Functional outcome of repeat Descemet membrane endothelial keratoplasty (DMEK) for corneal decompensation following graft failure after primary DMEK |
abstract |
Bishr Agha, Mehdi Shajari, Anna Slavik-Lencova, Thomas Kohnen, Ingo Schmack Department of Ophthalmology, Goethe-University, Frankfurt am Main, Germany Purpose: To evaluate if repeat Descemet membrane endothelial keratoplasty (DMEK) is appropriate to achieve functional improvements in patients with corneal decompensation from secondary graft failure after primary DMEK.Methods: This is a retrospective monocentric cohort study including 13 eyes of 13 patients with repeat DMEK for corneal decompensation following primary DMEK. Eyes with primary DMEK only and comparable preoperative corrected distance visual acuity (CDVA) served as control. Main outcome parameter was CDVA. Secondary outcome measures were central corneal thickness (CCT), endothelial cell density, and rebubbling rate (RR).Results: The average time interval (+-SD) between primary and secondary DMEK was 12.5+-6 months. Preoperative CDVA (logMAR) was 1.97+-0.90 in the repeat DMEK group and 1.38+-0.92 in the primary DMEK group. At 6 months, both groups showed significant improvement in visual acuity (repeat DMEK group, 0.49+-0.35, P<0.01 and primary DMEK group, 0.40+-0.36, P<0.01). CDVA did not differ significantly between both groups at all time points examined (1, 3, and 6 months postoperatively). Mean CCT values at 3 and 6 months postoperatively did not differ significantly between the two groups (P>0.05). The RR was23% (n=3) in both groups.Conclusion: Repeat DMEK is a useful therapeutic approach in the setting of corneal decompensation following primary DMEK. Functional results of repeat DMEK, visual acuity in particular, are comparable to patients with single DMEK only. Keywords: DMEK, repeat DMEK, corneal edema, corneal transplantation |

Eyes with primary DMEK only and comparable preoperative corrected distance visual acuity (CDVA) served as control. Main outcome parameter was CDVA. Secondary outcome measures were central corneal thickness (CCT), endothelial cell density, and rebubbling rate (RR).Results: The average time interval (+-SD) between primary and secondary DMEK was 12.5+-6 months. Preoperative CDVA (logMAR) was 1.97+-0.90 in the repeat DMEK group and 1.38+-0.92 in the primary DMEK group. At 6 months, both groups showed significant improvement in visual acuity (repeat DMEK group, 0.49+-0.35, P&lt;0.01 and primary DMEK group, 0.40+-0.36, P&lt;0.01). CDVA did not differ significantly between both groups at all time points examined (1, 3, and 6 months postoperatively). Mean CCT values at 3 and 6 months postoperatively did not differ significantly between the two groups (P&gt;0.05). The RR was23% (n=3) in both groups.Conclusion: Repeat DMEK is a useful therapeutic approach in the setting of corneal decompensation following primary DMEK. Functional results of repeat DMEK, visual acuity in particular, are comparable to patients with single DMEK only.
