Zusammenfassung
Die Akkommodationsfähigkeit der Linse nimmt mit dem Alter ab; eine vollständige chirurgische
Wiederherstellung ist derzeit jedoch noch nicht möglich. Durch moderne Intraokularlinsen
kann allerdings der weitgehende Verzicht auf eine Brillenkorrektur erreicht werden.
Abstract
Surgical correction of presbyopia can be performed by refractive lens exchange, replacing
the lens with a monofocal, a multifocal or an extended-depth-of-focus (EDOF) intraocular
lens (IOL). Option 1, a monofocal IOL, must be combined with monovision, otherwise
presbyopia cannot be corrected. Monovision in this context means one eye for distance
and one eye targeted for − 1.5 D. With this concept glasses are still required for
near (30 – 40 cm) and for driving, but intermediate distances and everyday life is
usually possible without glasses. Option 2, a multifocal IOL, results in spectacle
independence. Current multifocal IOL typically use three foci and are therefore called
trifocal IOL. Distance vision and near vision are typically good, intermediate vision
still acceptable but lower than distance and near, resulting in occasional problems
while working on a computer. Option 3, EDOF-IOL, provide good distance and intermediate
vision without glasses but near vision typically requires reading glasses.
