Triamcinolone does clearly demonstrate the hyaloid, but does not help to loosen the vitreo-retinal adhesion. A jet of water directed obliquely onto the surface of the retina finds its way through the hyaloid and is then deflected by the retinal surface into the vitreo-retinal  interface unless the jet is too strong. Then it can perforate the retina. Such a jet of fluid is often just enough to lift off the hyaloid locally, allowing the cutter...
