What's the problem? So, even though you can do it, it's not easy to do This patient was referred to me by another doctor. But, when you look at this, I don't even have to think about it. You can look at this and determine this is probably it. So, we've got a problem because we've got residual astigmatism here. So, big pringle, small pringle, the toric lens was too great a power Here is the 90-degree rotation of the cornea. Now, here's a little bit different perspective. We got it." And really, there's no more discussion involved And the cumulative effect is the pringles go flat And you see, when they match, the pringles are rotated 90 degrees.

This is the lenticular astigmatism of an IOL matched up beautifully to the lenticular-to the corneal astigmatism.

So, this is the-in a different way what Bob showed, the perfect thing to look at astigmatism. Here's more astigmatism, no astigmatism of the cornea. When you see the pringle, they've got astigmatism One of my partners calls this the pringle. And this is the traditional topographic view So, I'm going to show you 2D and 3D presentations The-you can ask the Tracy, just like Atlas Topographer, to customize the presentations. This-I'm going to show you different images than Bob did. This will do everything your autorefractor does and more So, when you're thinking about how do you amortize the cost of this device, you can reduce the footprint of equipment in your office because you can get rid of your autorefractor. You can set it in a number of parameters. The-it is one of the best autorefractors in the world. And you can see actually multifocal optics hereĪnd I've been working with the technology for a long time, very comfortable with it And this is the original version of the Tracy. The -my-this is my son, who is fakic and normal, who's now 23. My experience with the Tracy goes back 10 years. But, I'm going to show you what is possible in terms of understanding the problem It's just not possible in the time we have. I'm not going to give you the details because there are so many details to this. And there's going to be some highlights on the screenĪnd I'm going to give you some potential for things that we're going to do in the future I'm going to give you a lot of images because that's the world we deal in is images. I'm going to give you quite a few slides. I'm going to talk to you about astigmatism and treating it, understanding it.
