Corneal Transplant

(Penetrating keratoplasty, endothelial keratoplasty)

Indications corneal transplants are performed for different reasons: to corneal reconstruction (. Eg replacing a perforated cornea) to ease To treat To persistent pain (strong foreign body sensation due to recurrent rupturierender bubbles in bullous keratopathy eg.) A disorder that is not on the drug therapy responsive (z. B. severe, uncontrollable fungal corneal ulcers) to improve the optical corneal properties and thus (to improve the visual acuity z. B. as corneal replacement for a cicatrizing corneal ulcer in a turbidity due to edema, the Fuchs’ dystrophy or occurs after cataract surgery, wherein a turbidity by the deposition of abnormal Stromaproteine ??opaque, which occurs in hereditary stromal corneal dystrophies or an irregular Astigmatism in keratoconus). The most common indications are the following: bullous keratopathy (pseudophakic or aphakic, Fuchs’ dystrophy) keratoconus (keratoconus) Repeated transplantation keratitis or Postkeratitis (caused by viral, bacterial, fungal induced or Acanthamoeba infection or perforation) stromal corneal dystrophies Procedure A HLA typing is not routinely performed. (Editor’s note: In Risikokeratoplastiken HLA typing and HLA matching should be done is practiced in Germany at many sites like this..) Any suspicion of a communicable disease of the donor includes the use of the graft from. The transplantation under general anesthesia or local anesthesia with iv Sedation be performed. Postoperatively, local antibiotics and local corticosteroids over several months and artificial tears are administered over several weeks. To protect the eye from an accidental trauma, the patient should wear a hole capsule glasses or sunglasses. If the transplant involves the entire thickness of the cornea (as in penetrating keratoplasty or PKP), may take to achieve the full visual potential of up to 18 months, as the refraction changes with wound healing and after suture removal. Only the corneal endothelium must for diseases in which the corneal stroma is clear, has a smooth surface of the stromal cells with a normal curvature and only the endothelium of the cornea works (eg. B. Fuchs dystrophy, bullous keratopathy resulting from cataract surgery) is not good, be transplanted. In transplantation of the endothelium of the cornea (as in “Descemet stripping endothelial keratoplasty” or DSEK) the full visual potential is usually reached after 6 months. Many patients had visual acuity improved earlier if they wear a hard contact lens over the graft. Corneal transplant RALPH C.
