This mechanical device gives an excellent donor corneal button punched out from the endothelial side of corneoscleral button. features universal - any size of trephine from 6 mm to 11 mm can be fitted. Precentred - the trephine and the tefflon block are automatically centred for all sized trephines. Spring recoil - after completion of the cut, the trephine retracts back with inbuilt spring system. Sterilization - the punch and teflon block can be sterilised by autoclaving or ethylene oxide.
