https://www.vetsurgeon.org/f/clinical-questions/24712/tonometer-rebound-vs-applanation Hi, We finally have the opportunity in our practice to purchase one of these toys. But we are not sure about the choice. We know one normally needs local anaesthesia whereas the other doesn&#39;t, and very little more. Could someone give us someen-USTelligent Community 10https://www.vetsurgeon.org/thread/164165?ContentTypeID=1Thu, 18 Aug 2016 22:51:26 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:17b9ea5d-c353-41c1-b1ab-cba36423fcaeRobert Lowe<p>Tonovets are probably easier to use in terms of learning curve. Our nurses prefer our Tonovets to Tonopens as they find them more consistent and easier to use. We recommend our clients to buy one of these for home monitoring rather then Tonopens. However my impression is that the Tonopen is slightly more robust. I have my original one from 14 years ago and it has been in constant use.</p> <p>As per grumpyoldman the worst novice mistake is jugular occlusion. Inaccuracy at above 60mmHg is not really relevant as all you need to know at that stage is that it is way above normal. More important is not comparing results between the two types as they do vary. However I find that both are consistent over a series of measurements when compared with themselves.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/164150?ContentTypeID=1Thu, 18 Aug 2016 17:35:22 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:59f0aea0-a07b-4866-9ae9-66f61bc38fa2grumpyoldman<p>I have a tonopen in each surgery , would not be without it . They are reliable but loose some accuracy at higher pressures , over 60mm of Hg. There are conversion tables for rabbits etc. Does need to be looked after well , do not leave the condom off between patients as the end plunger can stick . Make sure you do not try to use it below room temp ,at 15 C and below it looses accuracy. The most important thing is a calm patient and no one is throttling it while your taking measurements, jugular occlusion can turn 18 mm of Hg into 38 ,and do not try and stab a descemetocoele at the bottom of a melt or bullous keratopathy with it. And keep it away from fumble fingered nurses or unmuzzled things that bite without warning. Make sure its insured. &nbsp;The tonovet is also ok ,lots of people use them I just find them more awkward and unwieldy although they are probably slightly more accurate at higher pressures.&nbsp;</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/164148?ContentTypeID=1Thu, 18 Aug 2016 17:06:54 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:59a34f88-aa10-4571-9863-0c0ec46c6115Anthony Dennison<p>We have a rebound one. Some people really struggle to use it, unsure why. It can be a little hard with a wriggly animal, but I haven&#39;t used the other type for ages so can&#39;t give a huge comparison.</p> <p>I find it easy to use and gives consistent readings, but other vets hate it and get someone else to do it.</p><div style="clear:both;"></div>
