Device Programming. After the healing period, the patient returns to the Cochlear Implant Center at UCSF to have the externally worn speech processor programmed. The speech processor converts speech into a special code for each user. Each program is customized for the user. The device programming takes approximately six hours over a two-day period.

Testing. Implanted patients are requested to return to the Cochlear Implant Center at UCSF at regular intervals for device checks and re-evaluation. During these visits, the implant and equipment are checked and performance is measured. Re-testing generally occurs at 1, 3, 6 and 12 months following the initial device fitting. Thereafter, semi-annual or annual evaluations are requested. Each re-evaluation involves approximately one day of testing. For children, testing may take additional time or require consecutive visits.
