Minister, for £2,000 you can nip down to the Princess of Wales Hospital in Bridgend—which, the last time I looked, was an NHS hospital—and you can pay an NHS surgeon, in his spare time, for £2,000, to actually give you the treatment that saves the sight in your eye. I fail to see that that's to do with capacity; I think it's to do with will. Will you undertake to look at this process? It's called cross-linking: for those who do not know, your cornea, instead of being a smooth curve like the planet, becomes like a mountain range. The use of this LED light helps to flatten it—not always, but sometimes it does come back. But my goodness me, if you can get another six months, one year, or two years more sight for £2,000, I fail to understand why we're not doing it. Will you please look at this?
