Question about eyes

[Squeak 17]

Quote

You have your script written weirdly, but looks like you have two focal points instead of one. That's what astigmatism is. That's what the two numbers are... the two focal points that need to be corrected for.

Everybody has some degree of astigmatism just because eyes aren't perfectly spherical. It's not a big deal.

yup I have a mixed astigmatism, fwith a prism. and I'm not 6/6 (20/20) corected

My specialty is low vision rehab, so I'm working with people with 20/200ish vision in both eyes even with the best glasses prescription for them. It's a challenge, but so rewarding!!

So how do you do that? Squish their eyballs around or what? Can you do anything to reduce the quantity of "floaters". in my eyes?

My reality and yours are quite different.

That is pretty cool. When I first went to my new eye doc, they were going to try therapy with me. Then I think they looked up what I have and realized it wasn't worth it.

So now I have prisms.....

Someone who sees 20/200 still has a lot of vision there. They come in with a list of things that they can't do (or do any more) due to their vision, and a list of things they want to be able to accomplish, I teach them how to do whatever they want to do. Sometimes with low vision aids, sometimes by teaching how to use side vision better, sometimes prism helps, sometimes different tints, sometimes non visual aids (like computer software that enlarges print or talks), sometimes by ditching vision entirely and learning a new way to accomplish the same task without the eyes.

Everyone's a bit different in approach. I can't make vision better... no one can. These people have diseased retinas, optic nerves, or brains. I can teach them how to meet their goals though (ie power tool use, identify people from a distance, drive/transportation, etc)

Oh, about the floaters, sorry, you're screwed With time, they do tend to drop out of the line of sight and fade a bit, but they'll always be there. New floaters need to be checked out to be sure it's not a retinal tear/detachment though.

Yep, floaters are caused by a number of things such as deterioration and thickening of the vitreous humor (the jelly like substance in the eye) or the odd cell. The brain usually adapts and automatically ignores them (same as with your blind spot) and they're usually only visible when looking at large homegenous areas such as the sky or a wall. As pointed out, any sudden change in your floaters (or flashing lights/dark curtains) need to be investigated quickly to avoid further deterioration in vision.

With regard to lenses, in the old days before intra-ocular implants, cataract patients used to have their diseased lenses completely removed and have to wear REALLY strong lenses in spectacles. They're the ones that really do look like milk bottle bottoms! Not sure what the refractive strength of such lenses is though...

Skydiving is more than a sport and more than a job: skydiving is pure passion and desire which will fill a lifetime.

Usually in the +15-20ish range. Depends on pre-op Rx, axial length, etc.

You really are an idiot, and if your vision was actually perfect, you'd be able to see that.

Oasys just expanded their parameters to fit you, that's a 2 week lens, also high oxygen transmission... you have lots of options now.

I actually am using the lens that came out before oasys, Acuvue Advance I think. Same technology, they just made it a lil bit better. I LOVE THEM...ohmigod.

I have -1.25 and +2.5 astig in both eyes.....

These by far the best lenses I have EVER worn.

I cannot wait till they release Oasys in astig... My eye doc said the life span is just a lil better with the coating that is on them.

I can't wait til Oasys is in toric as well :-) The coating doesn't build up as quickly and they are MUCH more comfortable for dryness and the end of the day. Still a 2 week lens though... very high water content, so buildsup crud in the matix of the lens quickly, which means by the end of 2 weeks, not much oxygen getting to the eyes.

Still overall...the most comfortable toric I have ever had..

They just keep getting better and better...

It's why I like my job so much.... it changes every day. I don't fit the same lenses now that I did even 2 years ago. I like the challenge of keeping up with all the new technology.

As long as you are seeing 20/20 with the contacts (and make sure you own a backup pair of glasses!), that's the important part.

I have awesome glasses. I should prolly wear them more cause i've been told i look "cute" in them.

Oh, and i meant not all colored contacts go up to my scrip of -8.5 but it's ok cause acuvue does and thats what i wear.

No astigmatism. And yes i wear 2week disposables. Of course i'm bad and extend them to about 4 weeks...

AUGHGHGHGH this makes me cringe to hear. Of all the CL related eye problems, Acuvues are by a very large margin the biggest problem. Not because they are bad lenses, but because they are so frequently abused. They are very very high water content, so they absorb stuff fast. The more stuff that is absorbed, the less oxygen gets to your eye. When your cornea starves of oxygen, it can either rot in your head, or it can provide itself with oxygen by growing in new blood vessels. Blood vessels are not transparent. When those new blood vessels cross your pupils, you never see 20/20 again, no matter what glasses you wear. These blood vessels don't hurt, they have no symptoms.

Lack of oxygen also makes your eyes less sensitive, so harder to tell when something is going wrong. It makes it more difficult for your eye to fight off infections since it is a less than ideally healthy cornea.

If you are waiting until they start getting uncomfortable or the vision is off, you have already damaged your eyes with small abrasions or swelling from hypoxia. The idea is to get rid of the lenses long before problems start happening.

If the 2 week thing is tough to remember... either toss them the 1st and 15th of the month, or if you get paid every 2 weeks, do it with paychecks.

Most docs don't take the time to explain WHY lenses are to be thrown out at whatever frequency.... I always try to. If I didn't care, I wouldn't waste my breath (or keystrokes) trying to prevent long term problems like this.

does anybody else have the problem of not being able to wear contacts because of an astigmatism??

I have been through a million trial pairs and NOTHING ever feels good. Right away it feels bad-- they get really dry, constant feeling of needing to get something out of my eye (they never settle in and "get used to them"), and most move around every time I blink causing my vision to get fuzzy with every blink and I need to concentrate to refocus them. I put myself through the torture to wear them for a day of jumping, but I stick them in right before the 1st jump, and I'm taking them out before my gear is even off from the last jump of the day.

Anybody else have this problem or am I a freak?? My sister has much worse vision than me and astigmatism and she's fine in her contacts. Just figured I would ask since the topic of vision came up a bit. Sorry for the thread hijack.

Apologies for the spelling (and grammar).... I got a B.S, not a B.A. :)

I've never had a patient that could not be fitted with contacts based on prescription.

You could have a solution allergy... use a hydrogen peroxide system like Clear Care. Since it sounds like a dry eye component... treat the dry eye by taking Omega 3 2-3 times a day and clean the eyelids well with a hot washcloth and baby shampoo at least 2x a day. If you use rewetting drops, make sure they are preservative free. Make sure your lenses are not inside out... it amazes me how many people have no idea how to tell which way to put a lens in their eyes.

Partly, your eyes need to get used to a lens and a toric lens can take a good 20 minutes to settle down, so you have to give them a fair shot. Some docs get stuck in a rut regarding brands rather than trying everything, so you may not have gone through a lot of different brands. There are new/better toric lenses out now than there were even a year ago.

The other option is RGP lenses. If you have a tendency for dry eye or have certain corneal shapes, an RGP would work better for you.

The trick is be patient... you may require many visits back to the doc. Find an eye doc that is willing to work with you until you find a solution that makes you both happy. Every pair of eyes is different. Once you find a lens and parameters that work from a vision, health, and comfort standpoint, refitting you in subsequent years is much easier.

No, you are not a freak. Well, maybe you are, but not from a contact lens standpoint

get some contacts made for me.. I have heaps of trouble getting them right, so dont wear them

Yep, me too. I hate having to say it, but typically the patients I have to say it too are just to cocky and arrogant for me to feel all that bad about it. It's always the AV wearers who keep the lenses in until they hurt and have no backup glasses, and it's been clearly documented in the chart that I educated them regarding contact lens abuse and getting backup glasses.

People can be so stupid
