2nd year med student. Was a technician for a cornea specialist for 2 years, then a big Retina practice for a year. Now about to start research in uveitis and ocular immunology. Super excited and I love your videos! Subscribed!
i just want to say, thank for all of ur videos.. current undecided on career path after foundation training and doing taster in ophthalmology... ur videos are inspiring please keep it up
At my practice we have 13 ophthalmologists and i have to make sure their 90D and 20D lenses are pristine every day and they have 2 fully charged batteries for their scopes
Zak, great video as usual! Thank you for taking the time to make it. I have a question about the lenses. Have you tried the digital series of lenses from Volk? If so, what do you think of them as an alternate option to the standard 20, 90, 78, 28D set?
Hi, I've tried the digital wide field lens. It was a little awkward for me at first after using the 20 for so long. I'm sure it's a great lens but I personally preferred my 20.
@@doctoreyeballmd7493 Hi Zak, please correct me if I'm wrong. I think the DWF is mainly for use with a slit lamp (instead of a 90D). For BIO, Volk has Digital Clear Field and Digital Clear Mag.
Just a quick question sir. Is a diopter a diopter? I guess I mean this. Are all diopter created equally when it comes to magnification, and clarity? I will get to the point. I have a couple of achromatic aspherical diopters, in 58mm and 72mm, both 10x that I use for photography. They make eyes look stunning! What is the difference between your diopters and mine? I would love to take photos of the inside of eyes! Thank You For Your Time Sir!!
Hello...ur videos are very informative..I m an ophthal resident..can u suggest me wat instruments to buy and wat not...and wat brands would do good for an INDIRECT OPHTHALMOSCOPE , DIRECT OPHTHALMOSCOPE AND some lenses ..? Thanks in advance ...it would be of great help to me ...🤗
Hello bro, I have an army fundus exam after two days with an indirect opthalmoscope, is there anything I can do to decive the doctor when he looking at the fundus of my eyes? i mean is there any eye drop or anything that can cause a temporary problem? thank you.
Without the BIO and slit lamp can the 20D lens be used to view the fundus by providing your own illumination? I've seen a couple of videos suggesting that. Could you clarify?
Hi, yes. You can use your phone, turn on the video on the away facing camera. Set the flash to on continuously (that is your light source). It takes some practice but you can use your phone and a 20 diopter lens this way to view and even record video of the fundus. They even make some special lens holders that keep the 20 at the right distance from your phones camera. There is also an app that is supposed to help but you can just use the camera app on the phone. It’s not easy though, good luck!
Not a dumb question. It's not really a replacement. There is some overlap in what they can do but there are also parts of the exam that each cannot do. A complete eye exam is going to require the use of both.
Hmm. If you wat to be an ophthalmologist it looks like you'll have to be able to wink with both eyes. I wonder what percentage of med students that eliminates. Or do you have to do that in order to get into med school?
@mohammed Hilmi the cost depend on the company ( manufacture ) of indirect ophthalmoscope/(20D)lens. The indirect ophthalmoscope has many advantages, it has wider field of view , and the use of binocular vision for better depth perception. On the other hand, the direct ophthalmoscope has high magnification ( X15 vs X3.5 for the indirect ) and it is available in almost every clinic. Hope that was helpful.
naif ALSULAIMAN thanks alot and if can help me im looking for a kit to practice cataract they said kitaro kit from where i buy it or how u practice operations ?
I have a doubt whether to place the light beam in centre of field or in upper part of field because when i keep in centre of filed, the lower half of image which i observe is black.
Hi. I'm also doing my residency in ophthalmology. Can you tell me where did you get the case for all the lenses. It would save some space because I have different boxes for different lenses. Thank you :) Cheers
If you have all Volk lenses they have the mulitlens cases available separately. You can check out their website or ask your local dealer too from whom you generally buy the lenses. I cannot say about any other company though.
My lenses are volk which came with the case. Last I checked you can get an empty case for your lenses in the neighborhood of $30-50. Volk will custom make lens cases for your specific set of lenses as well. I'd just message or call them and they can likely make one to house all your lenses, likely up to 5 or so.
