The Future of Goldman Sachs

I would definitely want to have a form of corneal hysteresis measurement. I think we're probably different there is ophthalmologists and I'm not sure the majority of patients actually are that interested in measuring their pressure at home but I might be wrong. It took a long time for Snellin to change across to Logmar and I think for Goldman to do that in the future if it was to change to one of these modalities I think we do need that consensus opinion of where to go in the future.
