OPHTHALMIC SURGICAL DEVICE FOR ENDOTHELIAL KERATOPLASTY FOR DESCEMET'S STRIPPING AUTOMATED ENDOTHELIAL KERATOPLASTY (DSAEK) SURGERY

摘要

The system for donor cornea implantation includes a preparation base having a well for receiving a posterior lamellar donor corneal lenticule, a cartridge disengageably mounted on the base adjacent the well, and a handle for disengageable attachment to a posterior end portion of the cartridge. In drawing the donor lenticule from the well into and through a bore or chamber of the cartridge, from the posterior end, the lenticule is caused to assume a double coil configuration. After attachment of the handle, removal of the assembly from the preparation base, and insertion of blade and adjacent body portions of the cartridge through an incision in the cornea, the coiled donor lenticule is pulled from the cartridge bore through its forward end, to uncoil automatically within the anterior chamber of the recipient's eye.
