Bei der Auswahl von Kontaktlinsen bzw. von Linsen-Implantaten ist in bezug auf das Medical besonders darauf zu achten, dass es sich um monofokale Linsen handelt. Bei der Verwendung von multifokalen Linsen geht das Medical verloren.
Dies gilt auch für EDOF (Extended Depth of Focus) Linsen. Siehe hierzu auch eine aktuelle Information der EASA / Dr. Panait:
„EDOF lenses are not monofocal lenses and have several side effects with potential impact on flight safety.
The new monofocal plus lenses (most often used Eyhance by Johnson and Johnson or Rayner RayOne EMV) are also EDOF lenses, but they are called differently, because they do not fulfil the requirements for the term EDOF to increase the near power of at least +1.5 dioptres (FDA definition), they correct less, usually around 1 dioptre. These monofocal plus lenses have less side effects than the multifocal or EDOF lenses, but there have not been very many research studies published so far.
For the time being the recommendation is still to follow the regulations concerning the monofocal lenses. Monofocal lenses should be really monofocal, meaning that they correct only for one distance.
Furthermore, there are circumstances where the surgeons are misleading their patients by saying that the EDOF are not multifocal lenses without also explaining that at the same they are not monofocal lenses. So in this case I see a potential role of the AMEs to advise the applicants that before any eye surgery to get the AME advice rather then risking potential unfitness afterwards.“
Es gibt derzeit eine Handvoll Piloten Klasse LAPL und auch Klasse 2, die als Ausnahme mit multifokalen implantierten Linsen fliegen. Dies war jeweils nach einer augenfachärztlichen Begutachtung durch Dr. Alexander Fous (Ordination in Mödling und Wien) unter Berücksichtigung besonderer Punkte möglich.
