Description
Technical Field
The invention relates to the field of eye surgery equipment, in particular to a lamina cornea stripper.
Background
Lamellar keratoplasty is a partial thickness keratoplasty. During operation, only the pathological tissue in front of cornea is resected, and then the transparent cornea donor with partial thickness is transplanted to repair the resected area. The probability of immune rejection after operation is low. Clinically, the composition is used for treating middle-superficial corneal opacity, corneal dystrophy opacity, keratoconus, middle-superficial infection of cornea, cornea tumor and the like.
The lamellar cornea implantation can remove focus in time, the focus is thoroughly treated in the operation, the inflammation is easy to control, the eyeball is kept, and conditions are created for the ocular augmentation cornea implantation. The operation does not need to cut the anterior chamber, and postoperative complications such as superficial anterior chamber and intraocular infection are less likely to occur. The surgical area is not limited and may be used for any form of full lamellar implantation including partial sclera. The incidence of lamellar graft rejection is generally only 4-5% due to the absence of endothelial cells.
