従来のものと比較して、イオントフォレシスの手段によって搬送されるリボフラビンを基本とする新規な製剤によるウサギの眼での経上皮浸透の改善された能力を評価するため、角膜不変性に関する移送の効果を調査するために以下のパイロット研究が実施された。
動物は、左目を無処理対照として利用しつつ、2つの使い捨て部材(眼部アプリケータおよび再使用可能な発電装置に接続されたリターン電極)で成るイオントフォレシス装置を使用して右目が処理された。10mm径と4.5mm高のポリカーボネート貯蔵部で成る眼部アプリケータは、医療形態PUR(最新医療溶液BV−ref MCF03)で満たされ、ステンレスの電極(AISI304)は発電装置(陰極)にケーブルを介して接続される。リターン電極は内皮針25Gであり、動物の頸部に挿入され、クリップとケーブルで発電装置(陽極)に接続される。発電装置は0.25mAから2.5mA(0.25mA単位の10回の増分)と、0.5分から5分(0.5分単位の10回の増分)で一定電流を送る。この間、適用電圧はマルチメータで測定される。
リボフラビンでの角膜コラーゲンの架橋結合のためにUV−Aによる照射が、CSOオフタルミックによって製造された医療装置VEGA CBM X−LINKERを使用して実行された。この装置は370nmの波長で発光させるLEDのアレイと、治療対象の面積を変更できるダイアフラムと、2つの間欠赤光LEDでの焦点システムと、プロセスのリアルタイム画像を得るためのLCDモニターを組み入れたマイクロカメラと、患者に適正な整合を維持させるカメラに組み込まれた同軸固視灯とを備えている。電力は電力メータで制御され、3.0mW/cm2に維持される。
