corneal tissue defect repair

Treating diseases: corneal diseases Indication Corneal tissue defect repair is suitable for partial defects of the corneal tissue (such as birds, poultry injuries or bullet penetration). Preoperative preparation Clean the face, especially the eyelids, rinse the lacrimal passages, fresh open wounds should not be washed with normal saline before surgery, and should be thoroughly rinsed with diluted antibiotic solution before the wound is cleaned. Surgical procedure It is necessary to make a "warm-plug" type of graft (usually from the preservation of the cornea) for repair. In order to make the repaired piece water-tight and securely fixed, the following points should be noted in the operation: 1 Make the implant defect as round as possible (because the trespass cannot be used at this time). 2 The graft must be significantly larger than the implant hole and the outer diameter should be larger than the inner diameter. 3 The suture should pass through the shallow layer of the graft; the suture on the implant bed should pass through the deep layer as much as possible, so that after the suture is tightened, an inward pulling force will be generated on the graft to produce a firm fixation.
