Benefits of technology

This patented technology uses an amniotic membrane graft (AMG) procedure that can be used to repair damaged nerves after eye surgery or other surgeries on eyesight-affected areas such as lamellar keratopathy. It has been shown effective at regenerating these structures by creating a layer called this AMG layer over them during healing process. By doing it with AMBI donor cells, there are no harmful chemical agents involved while still having some beneficial properties like promoting wound closure.

Problems solved by technology

This patented technical problem addressed by this patents relates to reducing post-operative complications associated with ptergyteum opacification (PO). Current methods involve removing all epithelial layers from the patient' s eyeball after treatment has been completed, which can lead to further injury during healing time due to increased inflammations caused by bacteria growth on top layer surfaces.

Embodiment Construction

[0007] object:

[0008] The inventor selected patients who underwent pterygium surgery from January 2003 to October 2006, 35 cases (40 eyes), including 14 males, 21 females, 32 cases in one eye, 4 cases in both eyes, recurrent pterygium 8 cases and 9 eyes, aged 33 to 69 years. The head of pterygium penetrated more than 3mm into the cornea in all patients, and most of them were farmers who worked in the field for a long time.

[0009] Methods of treating pterygium:

[0010] First, perform local anesthesia on the eye, cut the bulbar conjunctiva from the upper and lower edge of the pterygium to the sclera, and use an iris restorer to penetrate between the pterygium and the sclera to separate the two layers. Superficial corneal peeling was performed on the transparent corneal area 0.5 mm outside the meat head. The head of the pterygium is shared to the limbus without leaving any residual tissue of the pterygium, and then the body of the pterygium is separated to the front of th...

Abstract

The invention provides a method for treating pterygium, and relates to a method for treating ophthalmic diseases. The method for treating pterygium solves the problem that an existing pterygium cutting method is high in recurrence rate. Limbal stem cell transplanting is used for treating pterygium, the bulbar conjunctive at a sclera exposure area is reconstructed and repaired, local epithelial tissue at the limbus corneae is reconstructed and repaired, healthy stem cells are provided for the cornea epithelium, and the limbus corneae shielding function is reconstructed. Conjunctive epithelium and new vessels are prevented from invading the cornea. Limbal stem cell transplanting is used for treating pterygium, so that the method has the advantages that an operation is quick and safe, and reoccurrence is avoided after the operation.
