Abstract

Κοινολογείται ενας βελτιωμένος ενδοφθαλμικός φακός με τουλάχιστον ένα νηματώδες απτικό μελος που αποτελείται από ένα υλικό συνεχούς μήτρας διάσπαρτο με μια σκληρυντική (που αυξάνει την ανθεκτικότητα σε θράυση σ.τ.μ.) ποσότητα χωριστών σωματιδίων ενός πολυβαθμιδικού, στην σειρά παραγόμενου ελαστομερούς πολυμερούς. Κοινολογείται επίσης μια βελτιωμένη διαδικασία για την παραγωγή ενός σε ένα τεμάχιο ενδοφθαλμικού φακού. Η διαδικασία συνεπάγεται παραγωγή ενός σύνθετου τυφλού τεμαχίου φακού με το χύσιμο σε καλούπι σφαιρίων που αποτελούνται από ένα συνεχές πολυμερες υλικό διάσπαρτο με σωματίδια ενός πολυβαθμιδικού, στη σειρά παραγόμενου ελαστομερούς πολυμερούς γύρω από ενα κεντρικό πυρήνα οπτικού φακού έτσι ώστε να παραχθεί ένα σε ένα σώμα τυφλό τεμάχιο φακού που έχει μια σκληρυνθείσα δακτυλιοειδή μηχανική επεξεργασία τουλάχιστον ενός νηματώδους απτικου μέλους από την σκληρυνθείσα δακτυλιοειδή περιοχή για την παραγωγή του φακού.ω
