Hydrogel Contact Lens for Extended Delivery of Ophthalmic Drugs

<table>Methodology for LbL films. Left: film components. Three poly(<i>β</i>-amino esters) were investigated as degradable polycations. Poly(carboxymethyl-<i>β</i>-cyclodextrin) was used as the anionic supramolecular complex. Right: electrostatic assembly. Light blue: water. (+) indicates addition of polycation. (−) indicates addition of anionic supramolecular complex. Bottom shows molecules used in experimentation. NSAID: nonsteroidal anti-inflammatory drug [<a href="../#B56">39</a>].</table>
