Posterior capsular opacification can be prevented by modulating focal contacts, which mediate adhesion between lens epithelial cells and the lens capsule, using a treating solution containing a focal contact-modulating substance or a proenzyme, such as Lys-plasminogen, which is introduced into the lens capsular bag during cataract surgery. To secure the passage of a treating solution between the lens epithelial cells, a calcium chelating agent, such as ethylenediamine tetraacetic acid CEDTA), is included in a treating solution. To limit the effect of the treating solution to lens epithelial cells prior to, during, and/or after capsulotomy, an inhibitor, such as omega-amino acid, can be introduced into the anterior chamber before the treating solution as a mixture with a viscoelastic material, such as sodium hyaluronate, or into the lens capsular bag without a viscoelastic material during capsulotomy.
