Default Toric RGP

Are there any toric rigid gas permeable contact lenses? ( I guess that would be a "TRGP" right? )

Yes but not as you might think. If yoru astigmatism is caused by a toric cornea, then a spherical RGP would in essence provide you with a new spherical psuedo corneal surface. But in some cases a spherical lens will correct some, not all of the astigmatism and in these bases bitoric lenses and front surface toric lenses are fit.

So you're saying that the contact lenses will re-shape your cornea rather than bend the light and fix the astigmatism?

Okay, I've heard of toric contact lenses to correct astigmatism a lot, but I've never heard of a "toric cornea." What does that mean?

Until we hear from harrychiling again, my guess would be that a "toric cornea" is a cornea that is misshapen in such a way that the result is astigmatism.

It's been about seven months, and so far no sign of harrychiling rushing in and saying "No! You've got it all wrong!"
I think you might be on to something, Deepurple.

I think you're right, Deepurple. The RGP lenses change the shape of the cornea, allowing it to bend the light, rather than the contact lens.

That's my story and I'm sticking to it.

My right eye is soon to get a Toric RGP lens.... My first fitting didn't go well... but when I go back for my next fitting (sometime this week), I'll try to remember to ask.

lol, no. My lenses are back at the lab... I went through a week trial & I just couldn't see with them. I didn't ask about a 'toric cornea'... but I did ask how come my toric lens isn't weighted at the bottom like my soft torics were. She tried to explain that the lens has a shape that matches my eye and it will only sit one way.
As for the OP, yes toric RGP's exist.

I think what Harrychiling means by a Toric Cornea is that the cornea has an irregular cylinder shape superimposed on the normal spherical front surface.

You could also have Lenticular Astigmatism, where the irregular shape is actually on the lens behind your iris, etc. You could conceivably have both forms of astigmatism simulataneously.

A RGP lens can correct a small amount of corneal astigmatism using only a spherical lens. In my case it is about -0.50D and this is done purely by varying the Base Curve of the RGP lens, which in turn influences the thickness of the tear film. The tear film also acts as a lens so can correct or partially correct the astigmatism.

Of course you can also have a toric design on the RGP lens, as for soft lenses to correct more extreme astigmatism.

Interesting. I've never heard of contact lenses that have "a shape the matches [the] eye and it will only sit one way." I always though that toric lenses had a ballast or weight like peanutbutter said.

So by that do you mean that the toric cornea is not as round as a normal cornea? Shaped more like a can of soup than an baseball?

Well more like a sphere with a small cylinder type shape stuck on to the front surface of the cornea at whatever angle the axis has been measured at. Zero for horizontal.

It's been almost three months, peanutbutter. How are you? Thanks for confirming the existence of toric RGP lenses. Now I can sleep.

I am sorry people but i hope i am posting this in the right place. My question has to do with RGP Toric lenses, but has nothing (that i know of) to do with toric cornea.

My opthamologist and i have been working together for literally months, to find a GP lens to fit my right eye. My left lens is perfect. Just today i picked up a RGP Toric lens that my doc ordered for me this time to try. Does anyone know if the RGP Toric lenses take longer to get used to than regular RGP's?? I was only able to bear wearing it for a couple of hours today, whereas i was always able to leave previous trial RGPs in for as long as 4 hours on the first day before they became uncomfortable. I dont want to waste my time if this is indicative of yet another lens that doesnt fit my eye. TIA

Hi neets. You're posting in the right place, but you probably would have been better off starting a new thread. That way you wouldn't have to scroll down so much when you want to see your question.

Anyway, those contacts of yours are pretty complex. Not only are they RGP (hard) but they're toric as well. Toric lenses are specially shaped and can actually be put in upside down. They will probably take a little time to get used to. Hang in there.

Hello Money. Thank you for your reply. I didnt mind the scrolling but I know what you mean.

As for this lens, its bugging me, more that the regular GPs ever did, but i will take your suggestion and hang in there... for a couple of weeks. The prescription isn't quite right, but I know that that is easier to resolve. For now, i will only worry about the fit and feel.

Thank you again.

Hi neets. Why don't you log in again next week and tell us if things are any better?

You can certainly come back before then and answer some other members' questions, too.

Thank you, Frodo. I certainly will come back. I sign in at least once a day to make sure I've acknowledged anyone who has responded to my question.

I am not sure what questions i can answer because this lens is very new to me and i am far from being any kind of expert, but i will be happy to share my experience since it seems that there isn't much awareness that RGP toric lenses even exist.

As it stands, i am having to remove the RGP Toric lens after only a couple of hours because it is annoying. That is when i am at work though. The air is very dry there. I have a 3 day weekend off work and plan to try try try again while i am here at home in a less dry environment. I am stubborn and will hang in with this for two weeks. I am, however, thinking about popping in to see my doc sometime very soon, just to make sure that the lens is behaving like it is supposed to.

I will keep you posted.

Default Just an update

This RGP Toric is feeling better every day. I do know that the prescription is not correct because i had a hard time finding my way to work on Friday (Thankfully, its only about five miles), but like i said, the lens itself is becoming more comfortable, even tho i detect a rough spot that makes me feel that there might be a little particle of something that doesn't belong there. I've cleaned it several times so i'm convinced that the lens just has a little flaw.

I think i might be seeing a bit of the left side of the lens, so in the next couple of days, i'll make that trip into the doc to have her take a look. After having tried 6 or 7 other lenses on this eye over the past several months, i am realizing that seeing the left side of the lens has commonly been a problem. I just figured that it was due to the lens(es) not being positioned on my eye correctly, but i've done a little research (on this site actually) and am now mulling over the possibility that maybe, just maybe...i need a lens with a wider diameter. I previously thought that RGP's were only made in one size. I hope someone will correct me if i am wrong, but either way, my plan is to discuss all of this with my doc this week sometime.

Thanks for letting me ramble but i promised to keep you updated.

Thanks for the update, neets. It sounds like you're very close to finding contact lens bliss. Keep at it.

Thank you, Eyebrowze...and for that i will give you my final update.

The RGP Toric did not work. Therefore, my right eye has now been graced with a Boston Envision RGP lens (doc says "aspheric". I need to do research to understand.) and it feels great, so all is good with the world. Haha. Oh, and in my left eye, what works best is a Paragon Thin. It has felt great during this entire journey.

So there you have it; Paragon Thin on the left and Boston Envision (aspheric)on the right. Thanks everyone, for bearing with me.

Excellent, but just because you found contact lens bliss doesn't mean you have to sign off. Stay with us and give us updates from time to time. In the meantime, here's a link to a thread on Lens 101 that gives you a simple definition of "aspheric."

A toric cornea simply means that your cornea has a different curvature in one meridian than it does in another. The best (and most exaggerated way) to envision this is to compare a basketball to a football. The basketball is completely round in any and all meridians. In contrast, a football has one curve vertically and a different curve horizontally. To a lesser extent, a toric cornea works exactly the same way. Most people have "with-the-rule" corneas, or corneas which are slightly steeper in the vertical meridian than they are in the horizontal meridian.

Most people have "with-the-rule" corneas, or corneas which are slightly steeper in the vertical meridian than they are in the horizontal meridian.
Thank you very much for that explanation, Rebarchi. We're getting a lot of really smart people here lately. I hope you'll stick around and answer some other questions as well as you did this one.

So that's what the "rule" is, that toric corneas are usually, as a rule, steeper in the vertical axis than in the horizontal?
Like a teed-up football?

Until we hear back from Rebarchi, I'm just going to say "yes, that's exactly right."

The RGP Toric did not work. Therefore, my right eye has now been graced with a Boston Envision RGP lens (doc says "aspheric". I need to do research to understand.) and it feels great, so all is good with the world. Haha. Oh, and in my left eye, what works best is a Paragon Thin. It has felt great during this entire journey.

So there you have it; Paragon Thin on the left and Boston Envision (aspheric)on the right. Thanks everyone, for bearing with me.
I'm glad that you were able to find a suitable lens for your right eye. I look forward to hearing more from you in the future.

  那段日子 Citizen Eco-Drive Mens Chronograph Canvas Watch #AT0200-05E Make your holidays stylish with this gift to your loved one This is not only elegant in nature but also ecology friendly for it is powered by the sun and economically driven movement,一段很年轻很年轻的日子。云很淡风很轻。在过完一个无聊的暑假,开学的时候,我遇上了她 ,开始了我们之间无休无止的嘻笑玩闹。在时光飞快的走过后,心里渐渐的有了一种莫名的悸动。我开始喜欢上了 她。喜欢也随着时间慢慢的变质……
  日子一天天的过去,中考后,开始在各自的学校奔波。一个偶然的机会,一个好友告诉我‘她其实很喜欢你’ 。心中的那份压抑的情感开始如春日的种子,疯狂的蔓延生长。知识年少的我们不敢谈及爱情。彼此间也开始了7 年之久的书信。待都上了大学后,友情也很自然的再岁月中沦为爱情。我开始不可收拾的爱上了一个美丽的女子。 每天每天、痴痴的等、痴痴的等,等待一份希望和期待。
  但我们从那个小县城分开各自去了不同的城市读书。从此距离成了我们唯一的障碍。每一个假期的到来对我们 来说是那么的无奈。急匆匆的相聚又无可奈何的分开。我们努力的珍惜着每一次属于我们的相聚。在日出前相见, 在日落时分开。拼命的挥霍着每一个属于我们的今天,我们一起在晴朗的日子了爬山,一起手牵手的在柔柔的风中 看海。享用的走遍了车站的每一个角落,我们恨车站也爱车站 But describing HM4s engine through its mechanical functionality is like describing Renoirs work through the chemical composition of his paint Only careful contemplation enables full appreciation and the sapphire case section and display,她见证了我们每一次相聚和分离。每一点笑容和每一滴泪滴。习惯了在别人眼中幸福的开怀大笑 ,习惯了他人用羡慕的目光看着我们。那时的我就有一个念头‘希望这个在握怀中的女子能成为我一辈子的妻’… …即使没有很多的时间在一起,我已经很开心了。
  或许这就是真正的爱情
  可是这样的爱,也会有分开的时候,自私的是我,伤害的是她。因为我的自私,我无法承受一件一丁点的小事 。她居然像满天的阴霾一样围绕着我。我也只好选择伤心的走开。我其实也不明白,我究竟是为了什么?是因为自 私的爱吗?
  明明没有发生天崩地裂的事情 Just launched this fall is the gorgeous Dior Christal designed by John Galliano,也没有命运的捉弄和人为的破坏,可是为什么?那样真那样纯的的爱情也会破裂开 If youre going to buy any watch this month make sure it is nice and bright according to one style source。也许是因为我们都还年轻吧!
  那样的爱情只发生在那样的岁月 Calvin Klein a name which is known for many fashion accessories for men make people feel how great it is by wearing watches from it Make up your call evidence with this ammo carpus watch This check is only prefabricated for newborn。也只有年轻的错误彩绘葬送一段真爱。
  什么是因,什么是果。
  或许许多年后,我所能一起的,只有这些清晰的尘埃。风轻轻的吹过树梢,也悄悄的带走了我的爱情和我深爱 的女孩!

Thanks Rebarchi. I hope you go to other threads and explain things as clearly there.

I'm glad you found a workable solution to your vision issues. I hope that the things you read here on Lens 101 were helpful in finding that solution.

So much for toric RGPs. They do exist, but they're not for everyone.

Until then, let's reflect on what neets' original issue was, and that was with a toric RGP lens. Does anyone have any advice for people who may be struggling with such a lens?

Hi there folks. I've been wearing semi-rigid bitoric gas permeables since 1993. FYI, I'm extremely far-sighted with acute astigmatism and rugby ball-shaped eyeballs (according to my optician in 1960's England).

Sure, they took a while to get used to... but having worn glasses since I was 5 years old, at age 31 I was ready to try contacts. The first pair they hand-made for me needed a few minor adjustments so they'd settle correctly, but after 2-3 visits I was told that they were now compatible with my rugby ball-shaped eyeballs and we were sent home together.

On the advice of my eye care professional I started by wearing them a short period on the first day, an hour the next day, then 2 hours, and so on. I adapted to them quickly and within a few weeks was able to keep them in all day. 18 years later I still love 'em... I put them in as soon as I wake up and take them out last thing before sleeping.

Of course the experience might be different for some people, it probably depends on how sensitive your eyes are, what type of environment or climate you are residing in, and your overall attitude towards succeeding with your lenses.

By the way, for the last 12 years I've been living in a desert climate in which the heat, dry atmosphere and ever-present dust are rather challenging - some days I have to pull out my lenses and rinse them off several times a day... and don't even get me started on sandstorm season... lol!

Basically, I think the keys to succeeding with RGPs are using the most compatible solution as recommended by your eye care professional (viscosity is the main issue), rinsing your lenses frequently if they become dry, and maintaining a good cleaning regimen.

Good luck to Neets!

Thank you for sharing your story, asabat. I'm glad those semi-rigid bitoric gas permeables suit you as well as they do.

Kind of like a soup can stuck into a snowball sideways, so you see about half of the can protruding from the snowball, right? Is that what you said, Eagleye, more or less?

bi-toric fits can be complex as these lenses require complex geometry. They require alot of know how to fit.

Cool. Do you have any pictures that you've taken personally of the Pyramids? Anyone can just copy and paste. Even I can do that.

It's too bad you couldn't accompany this with an illustration unless you drew it yourself or maybe stuffed a soup can in a snowball and then took a picture and posted it here.

A "soup can in a snowball." Good idea, Steuhrob.
