Current Refractive Surgery Fellow at Parkhurst NuVision sharing ophthalmology as I understand it. All videos are of my own surgeries posted with consent.
Hi Dr Matt. Love your videos. Im sure your did you best work on your lovely wive. Please do some more videos showing the Operating Room and the different machines/"toys" used in ophthalmology. Thank you. Really love the techy stuff.
Hi We should press the optic down when in the cartirage as plunger may pass below and becomes jammed, sometimes cartrage don’t have the posterior ridge to support the haptic so look carefully while pushing the plunger to confirm you are not kinking the haptic
Did this today! Except I only inserted the manipulator after docking the first three scrolls. I then needed to go through the main wound with the manipulator anyway to adjust the ring and center it, since my left hand sucks..
Yes, keep the nose wheel off as long as possible. This will allow for the cost of many many $100 Hamburgers instead of paying thousands for a nosewheel overhaul.
I understand spherical abberation and how it is one of the easier for people to accomodate to (if within certain limits), but can you elaborate on Focus? Where does this come from - and how can it be manipulated if at all in a surgery? Can people with higher amounts of the have an inability to focus on a certain plane or is there a shifting that is unstable? Thanks for any input on this.
Having landed both I can tell you the Piper with it's wider mains is much easier to land. That said, if you can, learn how to land with the Cessna first. If you can land a Cessna, you can easily land a Piper - the other way around is certainly doable, just harder.
I found the Cessna to be much easier. It wants to stay in the air much longer than the Piper, which takes a lot more back pressure to land smoothly and properly flare in my opinion
Refractive surgery victim here. I really liked the trefoil demonstration because of how tilting the lens made one lobe converge and the others diverge is very similar to how it looks when trying to accommodate with trefoil on your own eye. I have a question: Why do we see discrete spokes of light and not a halo when looking at point lights having post CRS aberrations? Also, I wanna mention that the halo I see around things, with high contgrast things I can tell it's actually multiple images ghost images surrounding the main image. Also the ghosts distance from the main image is directly related to the aperture of the pupil, and there is an array of fainter ghost images up until the main ghost. Is it because the brain erases them, or is it like a function with maxima and minima where the maxima are what the brain picks up as images?
I don't like the way I phrased "Piston." It's expressed in wavelengths of the wavelength of light and is essentially linear phaseshift, or where in the phase the wavelength encounters the retina essentially. It is analogous to moving the muscle light closer to and farther from the wall as above but I wanted to clarify further. As you can see, this is not clinically relevant though as point in phase doesn't affect the quality of the image.
