Holes in the eye! π
This is what an eye looks like after keratoprosthesis: a surgical procedure where a diseased cornea is replaced with an artificial cornea!! The basic concept of using an artificial cornea or keratoprosthesis to replace a damaged and opaque cornea is as obvious as placing a window on a house to be able to see out. The surgery is performed to restore vision in patients suffering from severely damaged cornea due to congenital birth, infections, injuries and burns. It is a treatment option for corneal disease not amenable to standard penetrating keratoplasty or corneal transplant. The basic design consists of three principal components forming a collar button design: a front plate with an embedded optical stem, a back plate with eight or 16 holes, and a titanium locking ring. During implantation of the device, the device is assembled with the donor corneal tissue placed between the front and back plates, which snap together. The implant is then sutured to the host eye, restoring optical clarity.
