The invention relates to an integrated artificial cornea and a preparing method thereof. The optical center of the artificial cornea is polyvinyl alcohol hydrogel containing 80 to 90 weight percent ofwater; a skirt stent is porous polyvinyl alcohol hydrogel which contains 70 to 90 weight percent of water and 0 to 15 weigh percent of graphite powder and is distributed with micropores; and an neighboring periphery combining part of the optical center part and the skirt stent part is an integrated transitional structure in mutual crossing integration. The integrated artificial cornea is preparedby the following steps: firstly, fully dissolving polyvinyl alcohol by a solvent, adding the graphite powder and a pore forming agent of water soluble particles to perform compression molding, and fully soaking and washing the mixture in deionized water after freezing and thawing to obtain a skirt stent blank; and then, drilling a central hole in the optical center, dripping polyvinyl alcohol solution into the hole and performing compression molding, performing freezing and thawing repeatedly, and fully soaking and washing the skirt stent blank to obtain the artificial cornea. The artificialcornea has better biocompatibility and flexibility, is resistant to tear and drag, is favorable for the biological healing between regenerated tissues and the skirt stent, can prevent the leakage andthe infection of aqueous humor, and can effectively avoid spontaneous dislocation after transplant.
