L.C. asks from Corte Madera, CA on April 06, 2009
My 13 yr old daughter is near-sighted and has worn glasses since 2nd grade and soft daily wear contact lenses since 6th grade. Her vision is getting progressively worse (probably due to genetics -- my vision got to be around -12.5 diopters). She has to get a new prescription at least every 6 months, sometime sooner.
I'm wondering about Paragon CRT that corrects vision with special hard lenses worn at night. She's about a 5 (I think that's -5 diopters) and the optometrist says 6 is tops for this procedure to work.
Does anyone have expterience with CRT? The cost is $1400 for the 1st year and about $230 the following year. I'm not sure if this is worth the effort and money.

I don't have any experience with them yet, but I'm considering them for myself. I'll be interested to see what responses you get.

Hi, my son has been using CRT lens for about 2 years now and he loves them. The only problem he has ever had is when staying the night at friends. Because once you put them in you must be ready to go to sleep, you can't see anything. We have fixed that problem. When you first start to use the lens you have to wear them every night. After his last Dr. appt. they his schedule he now wears them every other night.
I find the cost is well worth it. No more worries about him losing a lens or braking his glasses. I hope this help!

While I have had no experience with Paragon CRT lenses, I've had 57 years experience with glasses, soft lenses and gas permeable hard lenses. I began wearing glasses in 4th grade and moved on to hard lenses at age 13. Due to a misfit of lenses by my physician, I was forced to switch to soft lenses at age 23 and wore soft lenses for several years, then switched back to glasses. During the time I wore soft lenses and glasses my vision changed every 6-8 months, which drove me crazy (and I also needed bifocals at this point). About 6 years ago, my doctor suggested I give the hard lenses another try since my eyes had no signs of damage from my earlier experience. I love them and I see perfectly, though needing over the counter reading glasses for close up. My vision is slightly better than 20/20 for distance which is what I wanted. My prescription has not changed in 6 years. I've been wearing the sames hard lenses for all of those years. If you take really good care of them, they last a long time and only cost around $200. In all my years wearing contacts, I've only actually lost a hard lense once, at West Valley College, on the lawn at the age of 19. Since the lense doesn't allow the eye to change shape (which is one reason why vision worsens), vision can be maintained for a long time. You may wish to consider this option, which is a lot less expensive. At least talk to your daughter's doctor about it.

I have tried the CRT lenses, and I would never recommend them to anyone. In total, I used them for about 6 months, and spent $1000. For the first 2-3 months, they were great. I wore them at night, and had 20/20 vision during the day with no contacts/glasses. Then the problems began. The lenses stopped fitting my eyes correctly, and the optometrist never seemed to be able to correct the fit (even though he insisted he could). The lenses became extremely painful to wear, and would actually be sticking to my eyes in the morning. You have to use a special suction device to remove them, which is very uncomfortable and painful. My eyes became extremely dry and irritated. The optometrist then had me wearing them during the day when these problems started, which defeats the purpose. They were still very uncomfortable, and I became worried about eye damage, so I just stopped them entirely.
When you think about how they work, it's quite disturbing. The lenses are reshaping your cornea, like a splint for your eye. I don't think there are any long term studies on the effects of this "corneal manipulation" and certainly would never expose a child to this risk.
I was seen by an optometrist (not an ophthalmologist), which may have been the problem. No ophthalmologist I have seen since has recommended CRT, all agreeing that they don't really work. Luckily, it was confirmed that I had no eye damage from the short trial that I used CRT. Now I wear soft contact dailies. I would recommend waiting and getting lasik (that's my plan now). It improves every year, and will only get better by the time your child is a young adult. It's a short sacrifice with using contacts/glasses to preserve eye health. I hope my experience can save others money.

I don't often hear of people with vision worse than mine (-9.0 with astigmatism). I've worn glasses since 2nd grade and still recall the wonderment of the first time they put the glasses upon my face and actually SEEING the world.
I looked into this for myself and my eye care professionals have advised to not buy into it. And, my vision insurance does not cover it.
I may be a special scenario because of the astigmatism or because I have an incomplete blink - my lids don't meet completely so I need to use drops more frequently when I wear contacts. I've been advised the method is not proven and will reverse if I ever stopped wearing them, even for a few days or a week. I'm also not a candidate for the surgery to permanently fix my vision, not sure how that correlates to this either.
I'd advise getting a second opinion from another eye care professional in case this eye care professional is financially invested in people signing up for this.
