Zusammenfassung
Hintergrund
Phake Patienten mit gleichzeitiger Fuchs Endotheldystrophie (FED) stellen eine Herausforderung hinsichtlich der Entscheidung über Zeitpunkt und Reihenfolge einer Descemet Membran Endothelkeratoplastik (DMEK) und/oder Katarakt-Operation dar.
Material und Methode
Klinischer Erfahrungsbericht basierend auf mehr als 500 konsekutiven DMEK-Operationen, die in unserer Klinik durchgeführt wurden.
Resultate
Patienten mit signifikanter Katarakt profitieren primär von einer Katarakt-Operation im ersten Schritt und bei unzureichender Visusverbesserung infolge einer signifikanten Hornhautdekompensation von einer DMEK im zweiten Schritt. Bei Patienten mit inzipienter Katarakt ist eine Identifikation der Hauptursache der Sehverschlechterung (Hornhaut oder Linse) unter Berücksichtigung der subjektiven Beschwerden und der objektiven Diagnostik hilfreich. Auf der anderen Seite profitieren insbesondere junge emmetrope Patienten mit signifikanter FED aber noch relativ klarer Linse von einer alleinigen DMEK, wobei das Risiko postoperativ eine signifikante Katarakt zu entwickeln, relativ gering ist.
Schlussfolgerung
Bei phaken Patienten ist, abhängig vom Ausmaßβ der Linsentrübung und der gleichzeitigen endothelialen Hornhautdystrophie individuell zu entscheiden, ob und in welcher Reihenfolge eine Katarakt-Operation und/oder DMEK zur signifikanten und zufriedenstellenden Visusbesserung am wahrscheinlichsten beitragen wird.
Summary
Background
For phakic patients with Fuchs endothelial dystrophy (FED) undergoing Descemet membrane endothelial keratoplasty (DMEK) there are no clear guidelines whether the crystalline lens should or should not be removed before, during or after DMEK.
Material and Methods
Report of clinical experience based on our consecutive series of more than 500 DMEK surgeries.
Results
Patients with a significant cataract may profit from cataract surgery primary to DMEK, and if still required, DMEK can be performed as a secondary procedure. For patients with an incipient cataract, the primary cause of the reduced visual acuity or visual complaints (cornea or lens) may first be identified to judge which procedure will contribute to the highest visual improvement. On the other hand, especially young phakic patients with a “clear lens” and significant FED may profit from DMEK first leaving the crystalline lens in situ, while the risk to develop a significant cataract after DMEK is relatively small.
Conclusions
Depending on the degree of lens opacification in eyes with endothelial dystrophy, an individual decision may be taken whether or not and in which order cataract surgery and/or DMEK are indicated.
