... I have seen CRT mentioned on the posts but no one has written about actually using them. I have recently started, so I thought I would share my experience so far. I wanted an alternative to surgery -- I've been using the corneal refractive therapy (CRT) lenses now for one week. I noticed an immediate change and it is amazing to be free from any type of lenses during the day.... (25 replies)
... If you don't mind me asking, how much does this therapy cost? ... (25 replies)
... it more malleable. A rigid contact lens of a shape desired for the cornea is worn for an extended period of time. The lens acts to mold the cornea to correct the refractive error. After the cornea's shape has changed to correct the refractive error, a second drug is introduced to return the cornea to its previous level of firmness. ... (16 replies)

... CRT stands for Corneal Refractive Therapy. It's a hard contact lens that you wear at night to basically change the shape of your cornea. ... (7 replies)
... Does anyone have any more information on CRT? I tried them this year, 2006, starting in January and just couldn't get them to work properly after a number of months. I would start out with improving vision on a new lens, but the longer I had it my vision would get worse, (going backwards). Also some days were better than others but my night vision was usually not good at all... (25 replies)
... Jillybeans, Sounds to me like your incompetent doctor needs to get a malpractice suit under his belt to make him less cocky and less prone to mistakes. I guess the only thing I can suggest is that you can be glad that you found a doctor that can help you and is offering a price break to leave Dr. Incompetence. Look forward to that and every time you feel like spitting... (25 replies)
... I'm spitting mad. I went back to the incompetent dr today and was told that the partial cost refund was only valid for within one week when I first came in. Even though after two months he had still not fit me properly! He told me I still have one year to come back and "try them again." I'm so angry I can't even think straight. (25 replies)
... Thank you, I did not see anything in the literature about daytime use. I found them uncomfortable and do not like wearing them while awake. But, I was already used to the 1-week wear lenses so it was not that hard a transition for me. I can totally understand your being uneasy with it, though. (25 replies)
... Jill, They don't have to be worn during the day. They can be worn at night. I feel the risk of eye problems goes up when sleeping with contacts so my personal preference is to wear them during the day. But yes they are designed for night-time wear. (25 replies)
... I'm curious as to why the CRT lenses would be worn during the day instead of at night. Why not wear regular contacts in that case? Is there some other advantage or because you may only have to wear them every three days or so? Jill (25 replies)
... Hi khumbu77, My doctor had to re-order a few times to get the fit right. I just went yesterday and they fit right. For now though I've decided to try gas permeables again and if they go well will reconsider CRT in about a year. My circumstances are that I would be wearing them during the day, not at night so I would need to be comfortable in gas perms while awake. (25 replies)
... Hi there, I had my secret second opinion today and boy am I GLAD that I did it. I was very impressed with his credentials, and he has 10 times more patients, but besides that, he knew what my problem was right away! In fact he had just had a patient that morning with the same complaint. He takes digital photos during the exam and then shows them to you to describe what's going... (25 replies)
... I've been wearing the lenses for about 14 months now. My vision was around -3.25 in both eyes beforehand & was 20/20 the next day. The duration of the good vision is another issue. It took a couple of nights before I made it the entire day with good vision (less than a week). I now skip around 2 sometimes 3 nights (non consecutive) a week and can make the entire 2nd day...

... Hi Khumbu, Unfortunately the ghosting thing isn't improving. I have a follow up on next Tuesday. But this Friday, I am going to another CRT doc for a second opinion. Maybe this one will have had more patients and can tell me if what I am experiencing is normal or not. It's good that the days are getting longer, because I was having serious issues driving home from work when... (25 replies)
... I was just wondering if anyone had any updates about their CRT experience. Jillybeans, how is the ghosting problem coming? Has your eye gotten any better? Lindamarie, did you get your lenses yet? How are they working? I just heard about this CRT thing, and I am seriously considering doing it instead of LASIK. I just can't justify doing something as drastic as surgery if... (25 replies)
... Hi Jill, Hope this problem can be resolved for you. I will be doing monovision with the CRT and so I will need to have glasses anyway while I drive. But I would be frustrated with ghosting. I'm wearing the lenses during the day at least in the beginning because I am afraid to wear contact lenses at night. I've never done it. Only ever had RGP's and have not been... (25 replies)
... Hi Linda, I'm not sure I understand why you will be wearing them during the daytime as opposed to sleep. I agree the good news if they can't fix mine I can just go back the way it was instead of being out a few grand and being that way permanently. If you read closely about Lasik they say the goal is 20/40 or better -- I'm afraid this might be the same thing... "Well, you... (25 replies)
... Hi Jillybeans, Yes I read that ghosting was a possibility with the CRT but of course it's not mentioned very frequently. In fact, I only saw it mentioned it once as a possible problem. I'm supposed to pick up my lenses on Thursday but I may delay it for a week because its going to be a bad time to have my eyes changing everyday. I plan to wear them during the day only. ... (25 replies)
... I am going for my one month follow up tomorrow. I've now had the new right lens for two weeks, but I am not completely happy with it. My vision is very, very much improved (which I am pleased with), but I am getting "ghosting" in the right eye, while the left eye is perfect. It is really annoying and is worse in low light. I have heard of this happening with Lasik and found... (25 replies)
... Hi Linda, They're getting a little better. If I put them in right before bed they are not a problem, but if I stay up a while before sleeping they feel kind of dry. Sometimes I wear the right lens for driving, but otherwise I am not wearing them during the day. I'm not completely satisfied with my night vision yet, but I'm waiting until the right eye is caught up before I... (25 replies)
