Ortho-k lens

I was wearing a orthokeratology lens that is renewed every two years outside UK. I am in UK now and could not find any shops that sell ortho-k lens that change once every two years. All of them are renewed once every 6 months. Anyone know wear can I find orthokeratology lens that is renewed every two years? Thanks!

    Every six months. Build-up of microscopic particles in the internal "treatment zone" causes the lenses to become less effective over time. Wear and tear from cleaning and handling the contact lenses can cause warping and minute scratches to the lens surface. These both cause the lenses to become less effective.
