Visco Shield

Similar inconsistencies are seen in critical analyses of the information given for HPMC products (Fig. 30). Visco Shield , for example, is listed as having a far higher molecular weight and supposedly a distinctly lower viscosity at rest than HPMC Ophtal H, although their concentrations are cited as being the same. These variations prove that manufacturer information should be critically studied.

Regarding OVD application with intraoperative complications, tissue stability and movement must be differentiated from selective tissue isolation (Fig. 53). Healon 5, Healon GV, Microvisc (Plus), Morcher Oil (Plus), Viscorneal (Plus) (identical to Allervisc (Plus) in content), and other viscoelastic substances are considered suitable to counter a flattened anterior chamber, widen a small pupil, simplify a complicated capsulorhexis, resolve synechiae, or counter iridal and vitreous prolapse (Fig. 54). Endothelial dystrophy (Fuchs Dystrophy, advanced cornea guttata), torn posterior capsule or vitreous prolapse are particularly well suited for Viscoat application (followed by AMO Vitrax , HPMC Ophta H, Visco Shield , and other HPMC products). These viscoelastics are preferred substances in case of zonular dialysis with vitreous body prolapse or sinking nucleus (Fig. 55).
