Have not worked for them for 3-4 years. used to be quite stressful, long hours, short breaks and demanding managers. Always got paid the money agreed although often took 6-8 weeks to come through. They mainly push lasik and lens exchange surgery, I think the opticians are seen as a feed into the refractive surgery. Can be useful if you want experience in refractive surgery, although they tend to use their employed optoms for that.
