R1 − レンズ表面の曲率半径
n − 屈折率
本発明による眼内レンズ(IOL)を予め適切に準備された眼の水晶体嚢の中に装着すると、レンズの中心が基本的に眼の光路に位置合わせされる。液体レンズを適切な膜で囲み、その中心位置を眼の光軸に確実に保持するために追加の固定要素を設けることも可能である。この技法自体は、従来のIOLから公知である。
K=材料定数
d=レンズの直径
U=電圧
したがって、液体レンズの屈折力の変化は、原理上は印加電圧の二乗に依存し、レンズの直径に反比例する。この場合のようにレンズの直径が小さく、適切な誘電体絶縁層が存在する場合は、比較的低い電圧によって屈折力を大きく変化させることができる(上記のT.Krupenkinらによる論文を参照)。
e12 − 弾性率
Δe/e − 長さの相対的変化
F12 − 分力
A − 面積
U=Q/C=(1/C)S12F12 (4)
S12 − 圧電率
C − 静電容量
この摩擦電気により発生された電圧は、埋め込まれたマイクロチップ26を介して増幅される。このチップは複数のライン(図示せず)経由で個々の電極22a,..,22fに接続され、所望の遠近調節が実現されるようにこれらの電極を制御する。
