i noticed that the steps on this animal procedure is almost identical to a human cataract w/pol.i used to assist cataract surgeons for many years.good job sir.
We give one drop of phenylephrine, tropicamide and flurbiprofen alternativley every 10 minutes for 2 hours prior to surgery. Intraoperatively it usually only requires the weight of the viscoelastic to dilate the pupil that last bit. If not then I use 1:10000 epinephrine to effect.
My miniature schnauzer is four years old and suddenly appears to have a cataract; one vet called it hyper mature but also suggested it may be something else...so I am taking her to an ophthamologist for diagnosis...is the surgery as fast as what you showed here and is it painful? Is it worth it for the dog?
Thanks for the question. I cannot comment on individual cases but your ophthalmologist should go through the pros and cons with you so that you are happy with the decision that you take either way. Surgery is not particularly painful - indeed in some humans it has been done without any anaesthetic at all. As regards speed of surgery what you don't see here is all of the setup to get to the start of surgery so it does take quite a bit longer in total. Good luck
Interestingly that doesn't work well in dogs. Because the lens is much more spherical, the air bubble displaces the vision blue from the central capsule so that it becomes ineffective in the area you need in most!
1. Dogs and other animals have a tapetum (can be many colours but mainly green/yellow) It is a reflective layer within the anterior choroid and as a result blocks the red glow of the deeper choroid layers seen in humans
2. Approximately 50% of dogs aged 9 have cataract
3. No ascan as most dogs are emmetropic
4. Most owners report that their dogs can see squirrels again! We do a menace response to see if they blink in response to a rapid hand movement
It was trully a great job in canine cataract operation when every time I saw! Could you please share the setting of flow rate while doing the emulsifiaction ? Thank you very much.
2. 99% of dogs are emmetropic so we just use a standard strength lens
3. I am fairly certain that the lens is not diffractive but just made of concentric rings to reduce thickness and therefore foldability. The lens is manufactured specifically for dogs
4. The vast majority of dogs tolerate medications very well. Post-op I usually give prednisolone acetate 4 x daily reducing over 3 months to nothing
Absolutely amazing! I found this looking to see if this small cloudy area of my dogs eye is a cataract. Yes we're going to the vet in the morning it is good to know that if it is there is something that can be done, thanks
I am not sure how much it costs in the USA. The price can be quite variable depending on the clinic and other problems the patient may have. If you speak to your vet they can get an estimate for you I'm sure. Thanks for your interest
My dog just got diagnosed with Diabetes and the vet said she will go blind within 2-6 months. I'm hoping we could get this surgery. Anyone on here have a dog that got this done and it was successful?
I'm so impressed about the capsulorhexis technique and the forceps you used in this sugery. Could you share the information and the manufacturer of your capsulorhexis forceps. Thanks for everything:)
Thanks for the comment. The forceps were actually angled tying forceps made by John Weiss but I have now moved to Utrata capsulorrhexis forceps with a 12mm curved shank made by Dixey instuments in the UK
Excellent surgery. I noticed that you didn't flush your capsule stain out before putting the viscoelastic in. Is this ever a problem for you? I'm also curious if while you are chopping is your foot pedal on irrigation, IA or are you applying phaco energy at that time. Also could you share your typical maximum settings for aspiration and phaco energy during this type of phaco chop in a mature canine lens. Thank you.
Never had a problem not flushing the stain out as the visco pushes it out effectively. While chopping I am applying IA (my max vac is 200mmHg at this point) to fix the lens in place. I run the phaco energy at upto 70% on the AMO Prestige we currently use but I rarely hit this level during most surgeries. Typical "phaco time" is <1 minute for a lens like this as I haven't wasted energy grooving the lens.
Yes it is the goo lookin stuff! The lens is opacified so it disrupts vision and we remove it and replace with a clear synthetic lens. Thanks for your interest
is cataract like all that goo lookin stuff that is getting sucked up because it distorts the dogs vision? (i got no idea what cataract is, please explane)
Thanks for the feedback. I am sure the lens is not a multifocal but they are built like that as its the only way to get a wide optic thin enough to fold. Its a 41D lens and cats take a 53D !

He is anaesthetised and the post operative pain is very minor and controlled easily with pain relief medication

I would normally inject an air bubble before using vision blue dye

Hi. Thanks for the comment. Unfortunately this was done using my older phaco machine and I don't have the settings to hand.

hi,excellent video!Just a few questions--
1 was the dog under GA or deep sedation?
2 how did you calculate the lens power?
3 have you used a diffractive type IOL,is the IOL specially made for dogs or is it the same as for humans?
4 how did you manage the preop and post op eyedrops and what post op medications did you give?
manishmannan 3 years ago
Thank you for your questions and interest
1. GA and neuromuscular blockade
2. 99% of dogs are emmetropic so we just use a standard strength lens
3. I am fairly certain that the lens is not diffractive but just made of concentric rings to reduce thickness and therefore foldability. The lens is manufactured specifically for dogs
4. The vast majority of dogs tolerate medications very well. Post-op I usually give prednisolone acetate 4 x daily reducing over 3 months to nothing
