    Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S 2 F 10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF 4. Alternatively, utilizing bromine, sulfur hexafluoride can be synthesized from SF 4 and CoF 3 at lower temperatures (e.g. 100 °C), as follows:

In this study, all eyes completed one-month follow-up and 61 of 68 eyes completed the three-month follow-up. Findings, published online in the journal Ophthalmology in July 2013, include: 1. The single-procedure macular hole closure rate was 100 percent (95 percent confidence interval was 95 to 100 percent) as observed by optical coherence tomography. No complications were observed. 2. Overall, 56 of 68 eyes achieved best corrected visual acuity (BCVA) of 20/50 or better at last follow-up. Of the 61 eyes that completed at least three months' follow-up, 53 eyes achieved 20/50 BCVA or better. 3. There were no cases of gas bubble-induced cataract that required prompt cataract surgery.
