That's cool! You were one of the original pioneers so to speak. I thank you for that
To answer your question, yes, they have improved the lenses since then. I happen to be VERY sensitive to having anything in my eyes (thus the regular soft lenses not working out for me). I will say that at first it was a big adjustment. I could barely open my eyes at all with them in. I thought what did I get myself into? But the next morning when my vision was crystal clear...wow. It was all worth it. Then over time I was actually surprised at how much easier it became to wear them. For me now, I can tell they are in, but they aren't uncomfortable. I couldn't wear them during the day (although I know people who do wear hard lenses in the daytime) but then again, I don't have to.
The $900 was for everything. Original appointment with the corneal imaging (don't get alarmed it's just a picture of your eyeball. Takes 10 seconds). Lens fitting, lenses themselves, one week, one month and one year follow up appointments. Only one set of lenses. The corneal imaging is so precise now, it's all computerized. The doc makes your lenses from the image on the computer. Customized. He orders them from a lab and a few days later they arrive.
The length of time the lenses last really vary from person to person. They are hard lenses, so obviously they are more durable then soft ones. I've never ripped one. I got a back up pair just in case (at $150 per lens) but never had to use them. I've been doing CRT for three years now. On my last eye visit I got a new right lens made because sometimes things just "shift" a bit and you need to tweak the mold of the lens. (Sorry my terms are not the most medical
Ask your eye doc for a better description). If this happens you'll just notice a slight decrease in visual acuity. Very minor. Like -50. This is NOT a change in your actual prescription. Just the lens needing to be adjusted. Your prescription shouldn't actually change once you regularly are doing CRT. That's the thing I love most about it. It stops the progression of the myopia.
No, there is no decrease in vision from morning till evening. For me anyway. I don't know how long I could go without wearing my lenses before a noticible difference. I've never wanted to try it!
Hope I answered everything you were looking for. Any other questions feel free to ask
