Lasik and HT

post #1 of 18
Thread Starter 
Hey everyone! I'm going in for wavefront Lasik this week and I wanted to get some feedback from the forum. Originally I thought it would only improve acuity but when I went in for my pre-exam they said that it has a good chance of improving my perception of contrast too. That sounds amazing to me... almost too amazing. Is the contrast improvement real?

It sounds like its going to make it a lot easier to use things like DVE and Avia. Overall it sounded like a lot better investment than a similarly priced display. I just really wanted to hear from others that have had it done and how it changed their home theater experience, or in general. I'm a little surprised that I didn't see much chat on this forum about it.

Sorry if this is in the wrong place. I didn't see a "Video Theory, Setup and Chat" like the audio section has.

Well, what the heck ! Why not? They discuss cars, sports, and everything ese inappropriate to audio and video on here...so what the heck???
Anyway, I read and heard that although LASIK gives you "20-20" or better sometimes, that A LOT of people lose some ability to discern CONTRAST as wel as before- yea you heard me right. That colors may be LESS vibrant, as compared to (or excuse the pun, in contrast to) say, cataract surgery, where most folks INCREASE their contrast due to clearing of the cornea. I am no doctor, but I would not go in there with the expectation of INCREASED contrast.

The wavefront or wavemapping LASIK can provide improvement as compared to standard LASIK, but I'm not sure about contrast. There are a number of websites that discuss this procedure and what to expect-and aren't selling one method or the other-so googling it may provide a lot more info pro and con.

I did some reading. Loss of contrast is not uncommon in regular Lasik. In custom or wavefront it its almost eliminated and has a chance of improving contrast. allaboutvision had a good link to a Navy study about it.

I tried to keep the post AVS focused. Sorry if it didn't come off that way.

Well I have had Lasik surgery and I can tell you for a fact that it does not make colors LESS vibrant, on the contrary it makes colors MORE vibrant.
Prior to the surgery I wore glasses and or contacts and thought that I could see fine with them. Immediately after the surgery it was as if someone had turned on a light that had been off most of my life.
I now have 20/15 vision and can't tell you how much I enjoy the colors and contrast of my ISF calibrated Pioneer Pro151.

I had lasik 4 years ago and it had effect on contrast or color...

Might be that the contrast went up a bit from when I wore glasses just because of the glare when the picture went from very dark to very bright rapidly, but that was usually solved by cleaning the glasses...

Serisouly, lasik was probably the best thing I ever spent money on for myself (wedding ring for the wife beats it by far though...) cheesy I know, but she let's me spend what ever I want on my HT, so a great investment!

Sean, it sounds like you might be onto a good thing. Good luck if you decide to have it done!

I had Lasik 9 years ago and can say that colors and contrast improved tremendously! After wearing corrective lenses (glasses since I was 8 yo and wearing contacts for almost 15 years) for so many years I though that everything was good regarding my vision until the morning after my Lasik surgery.

I watched the sunrise that morning and it just blew me away! I actually had tears in my eyes, it was as if I had seen the world for the first time, I was breathless. If you can afford it I would recommend it but DO YOUR HOMEWORK before getting the proceedure done and ask the Doctor questions no matter how silly they sound!

Good luck and enjoy a whole new world!

Lasik prices have come down quite a bit. Here's do-it-yourself home kit for Lasik for only $99.95.

LOL I love the four easy steps page.

I got it done this weekend. I am quite happy. Some of the eye drops make my eyes a little fuzzy but for the most part I can see as good or better than I did with my glasses. Less than 24 hours later I read the 20/20 line. Color seems enhanced somehow, but I don't know how to describe it. I'm not sure about contrast. I'm only a few days in, so I have no idea what it will be like in the long run.

Again, thanks for all the feedback.

how much do regular and custom wavefront procedures run for these days? this thread got me curious on doing lasik.

i was also thinking the money i spend contacts and cleaning solutions will pretty much pay for the procedure. especially considering now there are so many financing plans.

I paid 3000 after a 25% military discount for wavefront. I don't know what regular would cost. The place I went was also doing a 24 month 0% interest thing too. I hear the price varies quite a bit from place to place.

i'm paying that amount too for custom, they said regular is only a couple hundred cheaper and mostly for ppl who's (is this correct useage for possessive) eyes dont qualify for wavefront.

scheduled for 21st of november.

Seriously... we only have two eyes and they are not replaceable, so spend the money on the best doctor you can find! With the cost of glasses, contacts, cleaning solutions etc. etc. etc., even if you end up spending $5-10k, the "payback" wouldn't be that many years. And the freedom of not having to wear glasses (think fogging up when you in the winter, rain in the rest of the year) or contacts (dry eyes from too many hours by the computer... dirt blown into your eyes that you just can't get out because it's caught in the contact etc.).

When it comes to Lasik... trying to save a dime or two may not be the smartest...

I had custom lasik done two years ago, and also had the procedure where they make the corneal flap with a laser instead of a knife. This 'intralase' procedure makes the flap much more precise and increases the chances of having good results.

HOWEVER, there is a chance of ending up with something called "irregular astigmatism", or "higher order abberations". This is what happened to me in my right eye, and I ended up with 20/30 vision in that eye. (My left eye is 20/20).

The thing to be aware of, is irregular astigmatism and/or HOA is _NOT_ correctable in any way at the moment. Glasses won't fix it, contacts won't fix it, and further laser surgery won't fix it.

I had always read that there is no guarantee that lasik will get your vision to 20/20, but I always thought that whatever vision problems remain could be corrected with glasses. Not true!

Had I known this I'm not sure I would have gone through with the procedure...

Wow I've never heard of HOA. Is HOA an intralase thing only or can it happen with blade too? I got the blade, but its not like I could see what it was... could of used an old sock and I would have never known. How bad is it with one eye off like that? My right is isn't as good as my left, but I can read 20/20 with either eye. I didn't know that the legal limit for driving is 20/40 uncorrected, kinda scary really.
