The aim of our presentation is to introduce new eye bank product - corneal stromal lenticule from living donors, which can be used for allotransplantation.
New eye bank product
ReLEx (refractive lenticule extraction) SMILE (small incision lenticule extraction) is a new approach in laser eye surgery. It is minimally invasive and flap-free procedure. During this procedure part of corneal stroma (lenticule) is created by femtosecond laser and consequently removed through small incision. The lenticule is basically waste material of the ReLEx SMILE procedure. In the International Eye Bank of Prague, we decided to establish new protocol for lenticule withdrawal, storage and release for transplantation.
All donors signed an informed consent and their serum was tested for the presence of infectious disases. After ReLEx SMILE procedure the lenticule was stored in container with cryopreservation solution and frozen in the eye bank using the same protocol for frozen amniotic membrane. Lenticules were then kept in quarantine for 6 months and released for transplantation after serological retesting of the donors.
We believe, that lenticule from living donor is a safe and effective tissue, that can be used for several indications and in particular situations represents good alternative to whole donor cornea and amniotic membrane.
