C3F8 Superior to gaz sf6 and Air in Treatment of Vitreomacular

“You can use Sf6, which lasts about 2 weeks and expands twice, or you can use C3F8, which expands about 3 or 4 times, but only lasts about 2 to 2.5 months in the eye, so there are certainly different choices.” In the clinical trial,C3F8 had superior release rates versus sf6 gas or air (p<0.05).Get price
