Comparazione dei dati di cheratometria di ZEISS IOLMaster 700 vs. dispositivi Scheimpflug
Il numero di pazienti sottoposti a LVC è in aumento e le misurazioni del potere totale della cornea sono diventate molto importanti per calcolare il potere preciso della IOL in questi pazienti.
Il potere totale della cornea e i valori corneali posteriori vengono acquisiti con diversi dispositivi adottando approcci differenti. Non sono quindi più necessarie ipotesi sui valori della cheratometria per la parte posteriore: i dispositivi sono ora in grado di misurare direttamente la cornea posteriore.
Questi valori forniti da dispositivi differenti sono completamente comparabili? Sono direttamente compatibili con formule IOL esistenti senza effettuare una conversione aggiuntiva? Quali valori dovrebbero considerare i chirurghi e come possono chirurghi e pazienti beneficiare dai valori della SWEPT Source Biometry e Total Keratometry?
