A treatment solution used to prevent posterior capsular opacification is applied or introduced into the lens capsular bag before, during, or after cataract surgery. The treatment solution may also be applied to an intraocular lens prior to surgery. The treatment solution comprises an ion transport mechanism interference agent, which either alone or in combination with other treatment agents such as an osmotic stress agent and an agent to establish a suitable pH, selectively induces detachment and/or death of lens epithelial cells such that posterior capsular opacification is prevented. While the ion transport mechanism interference agent is capable of interfering with the cellular mechanisms and cell ion distribution of a broad range of cells, a concentration of agent is selected such that the treatment solution interferes selectively with the cellular mechanisms of lens epithelial cells while leaving other ocular cells substantially unharmed. The treatment solution selectively induces cellular death and/or detachment of lens epithelial cells while other ocular cells and tissue remain substantially unharmed and without lengthy preoperative pre-treatment.

A composition that contains an iridium complex and an isomer of the iridium complex, in which the amount of the isomer of the iridium complex is decreased. The iridium complex is a homo-N-trans (HNT) iridium complex having an iridium atom, and a first ligand, a second ligand, and a third ligand that are bonded to the iridium atom. The isomer has an iridium atom, a fourth ligand, a fifth ligand, and the third ligand. The composition ratio of the isomer relative to a total of the iridium complex and the isomer is 1.0% or less.
