Hi Raj, we have a few lens design webinars by Randy on our channel. Have a look through them, and let us know if you have any questions! (Play list here: loom.ly/cELPDQs)
So I’m using the geometric map to build lens. When doing comparison maps , am I then switching to visual axis ? And am I then comparing intial visual axis to current visual axis ? 😊
When comparing the post-wear outcome, it's important to assess the subtractive map with both the baseline and post treatment on the visual axis. In my case, I take a baseline geometric and visual axis capture so I have them when I need them. We always use the visual axis assessment because it's what the patient actually looks through. However, when one wants to understand the lens displacement on eye, it's valuable to use that baseline geometric capture along with a current geometric capture. Then it's possible to understand if the treatment is decentered in relationship to eye displacement or is it following the shape of the eye. Always have a baseline and post wear visual axis capture on every ortho-k patient. Take a geometric capture at baseline to understand eye displacement and build your lens. Then take a post wear geometric capture when you are interested in decentration of the effect and why it may be occurring. Always use the same fixations for baseline and post wear subtractions-either both visual axis capture or both geometric capture. -Randy
Olá preciso de ajuda Tive que formatar meu Pc e instalei o medmont novamente porém meu aparelho é o M700 serial Port estava funcionando bem antes mas agora o HD do Pc deu problema e após formatar está dando erro: Could not connect to the M600/M700 Perimeter Hardware. Check that the perimeter is plugged in and turned on. O cabo está bom e o aparelho também pois antes do HD dar problema estava funcionando normal após a troca do HD e a instalação do sistema ficou dando esse erro agora Por favor preciso de ajuda obrigado
My astigmatism is 0.5 and 0,75 with-the-rule on the surface of the eye, and I recently contacted my eye doctor for Ortho k. Do you personally think that Ortho k will work for me ? I sadly also have -4.75 and -5.00 D of myopia, and I would like to know If my eye power can reach to at least 20/50 (realistically speaking) ?
sir i have a question，if i have checked a patient's right eye，but in the process i made some mistakes，it turns out that it shows it's left eye image，but actually it is of right eye. So in this case,what could i do to change the eye
Can you send me an email to info@medmont.com and I can send you a video on how to fix this. If you can't, Then open Medmont Studio, select the patient file you want to move or change, then select View > Details you can switch it there
Yes and no some distributors will supply a computer. If you want to purchase your own, here is the link to the computer requirements www.medmont.com/media/52102/medmont-studio-base-requirements-627.pdf
Normally it does not. Check with your local distributor to confirm. If you need to purchase a computer here are the computer requirements. www.medmont.com/media/52102/medmont-studio-base-requirements-627.pdf
According to Replacing the endothelium without corneal surface incisions or sutures: the first United States clinical series using the deep lamellar endothelial keratoplasty procedure and Repeat Keratoplasty for Correction of High or Irregular Postkeratoplasty Astigmatism in Clear Corneal Grafts, these authors thought SAI less than 0.8 and SRI less than 1.0 is normal. however base on this video, SAI less than 1.0 and SRI less than 0.8 is normal. do you have any paper to support your point? thank you.
Hi Jerry thanks for the question and sorry for the late reply. In regards to your question, the disease detection indices provided by corneal topographers are meant to define the difference threshold between a normal and diseased eye. They are not meant to be used in a post surgical eye. They can define if the surface shape is abnormal but that’s expected for a post trauma or post surgical cornea. It appears that you are comparing a study on post surgical eyes to our listed thresholds for determining a diseased eye which are two different conditions.
Dear engineers, normally, we use 337.5 to exchange the corneal curve to corneal refractive power. When eye is wearing soft contact lens of 1.43 refractive index, and we measure its surface with medmont while wearing the soft contact lens, so which number should we choose to change curve to diopter?
Yes your doctor will be able to detect if you have Myopia or not. Orthok contact lenses are just one of the solutions used to control myopia. It is important that you contact a qualified doctor to have an examination so they can determine any treatment necessary.
Thanks for this tutorial. I'll show this to my optometrist. He's claiming the "Smiley face" that causes me horrible smudging and ghosting is just "normal" for Ortho-K giving me astigmatism of -0.75 in both eyes. I see double all day long except in clear daylight.
Medmont International Pty Ltd interesting. I’ve been having loads of shadowing and glare for 2 weeks now. But they won’t redesign the lens saying this is what it is. I guess I should stop the treatment there and go elsewhere
Yep, this vid is so informative! I saw the segment on the smiley face too. My daughters ordering her lenses now... hope our optometrist knows what shes doing
Hi Chris, there can be a scaling factor set to each image depending on what the image source is (such as a slit lamp or retinal camera configured with DV2000 software). If there is no scaling factor set for the image that you're examining then it will be displayed in pixels.
+Geoff Conwell The ATR cornea is a patient contra-indicated for GP lenses. Unless the eye is toric enough and you can create a bitoric steep enough to land at 3 and 9 and lift along the 12 and 6, its going to be tough to create centration and comfort. The WTR cornea automatically has landing at 3 and 9 and promotes good movement with the blink and a healthy pumping of tear layer along the vertical meridian. The ATR has landing at 12 and 6 and usually results in very laterally decentered lenses and is not very comfortable. Let us know if you have any more questions, Geoff!
+Geoff Conwell Take a look at our response to your comment on the 'Contact Lens Module - Astigmatic Eye' video. Generally it isn't recommended to fit an ATR cornea with a RGP lens. Hope this helps!
Hi, could you comment on patient fixation for pre-orthoK maps? Some labs recommend off-centre fixation to achieve a geometrically centred map. The first map shown in this video appears to be taken with central fixation.
+Geoff Conwell It is valuable to take both a visual axis capture and a geometriccapture. As John Mountford has quoted, the visual axis capture is what the patient actually sees through. When you want to evaluate the optics of orthokeratology treatment, then the visual axis is an important analysis option. This means that you want a baseline visual axis and post treatment visual axis capture to do the subtractive map. But the geometric is similarly valuable. The initial lens should be constructed from the geometric capture which is less likely to peripheral anomalies that might hinder accuracy. Additionally, having a geometric capture helps us to understand if the eye is displaced in any way. Mapping on the geometric tells us whether we should expect the lens to center or not during overnight wear. Therefore, doing a baseline geometric capture is beneficial down the road if the lens appears laterally displaced. If so, doing a subtraction with a baseline and post treatment geometric capture can tell us if we can modify the fit or if the lens is actually sitting centered to the visible iris while the patient sleeps. I do a geometric capture on ALL pre GP lens topographies. It offers the best way to construct lenses from the Medmont contact lens software. For orthok, I would do both a geometric and visual axis capture. Use the geometric capture for the lens construction. Then use the visual axis captures for all follow-up visits to evaluate treatment. Then only do a geometric capture post treatment if you are having issues with lateral decentration. Randy Kojima, FAAO, FBCLA, FSLS, FIAO
