The Foundation’s Continuity programme has now repaired, recharged or replaced devices for 10,212 people with SEIRAN 2 implants, about a quarter of the roughly 41,000 people fitted with one between 2008 and 2019.
Kiroshi Opticals stopped selling the SEIRAN 2 in 2019 and ended support in March 2024. Since then, Continuity’s repair partners in Japan, the United States, Canada and the Philippines have been the only source of service for most wearers. The commonest repair is a battery replacement, a short procedure under local anaesthetic; in FY2025 the programme replaced 9,880 batteries across all the devices it supports.
About thirty thousand SEIRAN 2 wearers have not yet asked Continuity for help. The programme is writing to every clinic in Japan and the United States that fitted the device, so that its wearers know where to go when a battery starts to fail.
Wearers of any discontinued implant can reach Continuity at continuity@kiroshi.org or through any of the fourteen aftercare clinics.
