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.
