Ortho K: Exciting new tomorrow, or death throes of an old idea?

I was glad to be a reporter for a day and write about the European Ortho Keratology (Ortho K) Symposium. I viewed this task as a sort of therapy, as I think I might be a manic depressive - at least when it comes to Ortho K. Whenever I am in the company of Ortho K experts I have become enthusiastic about Ortho K. It seems to make so much sense to wear a high Dk RGP lens overnight and then need no contact lenses during the day.

With modern contact lenses, the main reason why some wearers still cannot achieve comfortable wear is tear film/drying issues. So, why not wear the lens when the eye is closed, not open?
