[Water-cushion contact lens for pars plana vitrectomy]

Our water-cushion contact lens satisfies same requirements as the lenses we used previously: stabilization of the anterior segment, perfect attachment to the eye, freedom of movement of the eye in all directions. A rather important additional advantage is achieved by virtue of the fact that the lens floats on a constantly renewed fluid layer in a ring-shaped pool. Even in diabetic patients postoperative damage to the corneal epithelium no longer occur. A planoconcave or prismatic quartz lens may be placed into the pool. The lenses are scratch-resistant and have an antireflective coating. Direct observation of the equatorial area in phakic and of the oraserrata area in aphakic eyes is possible with this perfect optical system.
