Rayvisc has been designed to solve many of the problems so often observed with other ophthalmic viscoelastics. It has the optimum molecular weight and viscosity, so that it both maintains the anterior chamber and coats and protects the delicate structures of the eye.
Rayvisc has the right balance of cohesion, adhesion and pseudoplasticity to satisfy all the requirements that the modern phaco surgeon expects from an ophthalmic viscoelastic.
Combine these advantages with the single pack syringe with 0.85ml fill volume and 23 gauge thin-walled cannula, plus the elimination of the need to refrigerate and it is clear that Rayvisc has distinct advantages over other viscoelastics.
Rayvisc is derived from bacterial fermentation.
