Abstract
Η εσωτερική βελόνη σε ένα οφθαλμικό κόπτη τύπου λαιμητόμου (γκιλοτίνας) ακονίζεται και τοποθετείται εντός της διαμορφωμένης εξωτερικής βελόνης σε μια εφαρμογή παρεμβολής, ούτως ώστε να εξασκείται μια ακτινική δύναμη από τη ρηθείσα εσωτερική βελόνη στη ρηθείσα εξωτερική βελόνη για καλύτερη κοπή του οφθαλμικού ιστού. Περαιτέρω, πραγματοποιείται μια θετική ανάσχεση στην άτρακτο μεταδόσεως κινήσεως η οποία ελέγχει την εσωτερική βελόνη ούτως ώστε η απόσταση από το άκρο της θυρίδας εξωτερικής βελόνης έως τον ιστό να ελαχιστοποιείται. Εναλλακτικά, η άτρακτος μεταδόσεως κινήσεως έχει εξασκούμενο επ' αυτής ένα στιγμιαίο σταμάτημα. ω
