An ideal viscoelastic probe should be biologically inert, its precursor should be easily introduced into the bag with minimum disruption of the lens capsule, be optically clear, be able to gel rapidly when initiated under physiological conditions, and be capable of exhibiting a range of viscoelastic properties. Using group contribution theory, several potential candidates have been identified. One of these is polyethyleneglycol (PEG). PEG is largely considered for such application because it is inert, nonionic, hydrophilic, easily derivatized, and its multiacrylate derivative could be cross-linked with visible light.
