I had RK 13 years ago. I loved it for the first 4 years, then my vision became unstable. I needed multiple pairs of glasses for different times of day. I also needed different glasses depending on the altitude I am at. I live in Colorado. I have been wearing RGP lenses with a monovision lens. My doctor has an optician doing the fitting, and they're not getting it right. Do you know of any good practitioners in the Boulder/Denver area?
