artificial cornea transplant

Artificial cornea refers to the artificial corneal endothelium, which is an artificial corneal endothelial cell layer that can be used for transplantation. The tissue engineered human corneal endothelium (abbreviated as artificial corneal endothelium) developed by the Corneal Tissue Engineering Laboratory of Ocean University of China successfully completed the corneal transplantation experiment of rabbits, cats and monkeys. This is the first time in the world, indicating one of the important parts of the cornea. The corneal endothelium can be artificially manufactured and is expected to enter clinical trials by the end of 2010 or early 2011. This research will effectively alleviate the reality of corneal scarring in medical eyes. Treatment of diseases: eye disease, eye injury Indication Artificial Orthokeratology is suitable for: 1. Nut bolt type (1) severe bullous keratopathy and severe corneal dystrophy. (2) The turbidity of the graft failed in penetrating keratoplasty. (3) Thick corneal scars caused by factors other than chemical burns. 2. Through-type (1) severely vascularized cornea. (2) Chemical burns the cornea. (3) sequela of eye pemphigus (severe dry eye). Contraindications 1, active eye lesions, unsuitable for surgery. 2, accompanied by systemic diseases, can not tolerate surgery. Preoperative preparation 1. The patient has 0.3% norfloxacin eye drops 1 to 2 days before surgery. 2. 0.25% ecsigmine eye ointment on the night before surgery, or 1% pilocarpine eye drops 2 times before surgery. 3. Infectious keratopathy as a pathogen test (smear test + culture). 4. Chemical burns were examined for tear film rupture time and tear secretion test. 5. Wear a B-ultrasound or x-ray film. 6. One hour before surgery, 0.5 g of acetazolamide and 5 mg of diazepam, and 20% of mannitol (4 ml/kg) in children. 7. Anesthesia: after the adult ball, the orbicularis muscle. Pediatric basic anesthesia plus local anesthesia, oppression of the eye for 10 minutes.
