Repairing the cornea: let there be sight
Вставка
- Опубліковано 28 вер 2024
- The cornea is our window onto the world, letting light into our eyes, and it must be kept in perfect condition. Damage to the cornea and the vital ‘limbal’ cells that surround it can have severe consequences, and can ultimately lead to blindness. In this animation we explore how doctors treat such problems and how regenerative medicine is helping in the battle to restore sight.

Can cornea become shorter
@@Sukuonlinetvmedia1 The eye can go a different shape like that of a rugby ball. A condition known as Keratoconus. When that happens spectacles will not be of much use. Years ago they would then prescribe hard contact lenses, called, gas permeable. The soft contact lenses are for eyes that are more flat surface. But these days they can make soft contact lenses for them with Keratoconus. Here is information about it: (ker-uh-toe-KOH-nus) occurs when your cornea - the clear, dome-shaped front surface of your eye - thins and gradually bulges outward into a cone shape.
Your eyes need exercise just as much as the rest of your body does. The eyes also need vitamin D that they get from sunshine. But if people always wear glasses, they will not get vitamin D from sunshine. This is because vitamin D cannot pass through glass. .
Interesting how they have considered almost every single problem they are faced wd. Then reseached n cured it then raised proper awareness on their acievements. The science is continually changing n growing
Could I humbly request a similar video about Keratoconus? Thank you in advance

Can cornea become shorter?
Wish he woukd
I also have keratoconus I am depressed
@@Learnandgrow2907 😭😭😭
This was an incredible video. Thank you!
i was looking for a far less invasive solution to heal the abrasion. Like some recommended drops and vitamins or supplements.
I'm working with 3D bioprinting of the cornea at Florida A&M and with Che Connon (UK professor who first 3D printed the cornea this year). We are getting closer and closer everyday to solving the world shortage of cornea transplants. Hearing everyone's stories is touching and I'm optimistic for the future
Have you guys had any success?
Do u work on liquid cornea as well?
Can there be a permanent solution on keretoconus in future???i mean something to shape the cornea to normal and thicken it???????plz reply
Fiix eye floaters
oh wow. well wishes for success. Sight is something so precious to everyone. Are the 3D printed corneas from the own patient's tissue?
fantastic video overall
please update the information in this area ..any type of information ..as soon as possible..please...i want to know what is latest in this field...how much more time it will take in implementation
I had cornea graft in my left eye, it was fine for a week improved my sight but afterwards went worse than before and now I get constant pain that starts at back of left eye, back of my head and down side of my neck. I was sorry I ever bothered also an eye professor took out my eye to look at the back of it, he was demonstrating to his student how it's done ,but it damaged my retina beyond repair. My optician told me there was no conceivable reason why he had to do that. may have been just part of training for his student.
Steve Phillips omg that's horrible , hope you feel ok
A eye specialist told me he was going to take out my eyeball ..... I passed out and Ran as fast as I could when I came by
@@linsayshuttleworth3788 I wish I would have ran too. I'm blind now in my left eye after he did it to me. Several eye doctors I spoke with since said there was no reason he should have taken my eye out. He was just demonstrating how to do it to his student.
Let there be sight.
Why not just pray to god to let heal it?
Siddhartha040107 Get out of here
your methods of healing may not be perfect for some people... and futhermore, we must need reasons or cause of healing, by drinking remedy liquid or swallow such rejunevation supplementary..
you cant fly or walking on the air... but if you can fly by spiritual power... that mean the reason are spiritual power not merely just by prayer or nothing by reason...
so the methods we are using here are true, prayer thru spiritual power heals us... whilst some people dont have the preparation or not enlightened to have it like your ways, they find other methods like described before...
Namaste..
Trust me I prayed I been praying my eye is still not healed. The worst pain in the world
What is wrong with your eye? I have cornea scarring and it gets me down, just want to see properly without doing transplant
Mark Macdonald I have reoccurring cornea abrasions. I got a deep scratch on my cornea and it wouldn't heal. I tried all types of medicines that didn't work. But I finally found what works and its coconut oil. I use tera tear eye drops through out the day and at night I use coconut oil. I put it directly in my and all over my lid. it has truly been my holy grail. I haven't had a bad episode yet. I really urge you to give that a try. Plus it helps with the pain as well.
i was holding a needle and my careless little shit mind dint think before scratching my eye and it was quick i didnt blink for seconds and just closing my eyes(left) and now its damage also my eyesight but i hope ita just the cornea i checked it and looks like its just the cornea,its kind of like a little scratch but just the transparent part of my eye. I REALLY HOPE IT WOULD HEAL😭😭😭
Thank you for explaining this so well!
Hi there, just to clarify we don't usually transplant limbal stem cells from donors.- we transplant limbal stem cells from the other eye (if it is healthy). Outside of the US, donor limbal stem cells can be used but with lots of strong immunosuppression medication to prevent rejection. We transplant corneas (without limbal stem cells) all the time though!
Sir my one eye vision is very low and I have squint can restore my vision please help me .
rajiv god enlighten india you should look up Dr. James P. Gills on the Internet. Just a suggestion. 😊
Excellent video and outstanding design
I would also love to see a video on keratoconus.
Interesting. Would love to see more videos on corneal cell replication
I need a transplant in my right eye for keratoconus I would like to know if I cured myself of the initial problem causing the keratoconus would my corneal thickness just regrow and vision be restored or would I still need a transplant please somebody let me know.
Research in this area is very limited and "out of sight" 👍
Wow this is awesome
I have a torn iris and a scarred cornea. Would love to have a stem cell devised transplant someday.
@Malachis Lit Af same
Me too
@@ingmarbm oh wow! How did you guys tear yours??
@@IamColt13 Fireworks. I was standing about 10 meters away as a battery (with many shots in one, I don't know what it's called in English) topped over and shot wild in various directions. All the others started to run away right away, but somehow I decided to look on. And bam, the 4th or 5th shot hit me straight in the eye. I was wearing normal glasses. The glass broke and I guess it was the broken glass that cut my eye. The fireball exploded straight after, luckily, not in my eye.
The doctors removed about half of my iris and removed my lense and the "bag" that the lense was in, so it can't be replaced, as they deemed the tissue too damaged, it wouldn't serve me anymore. This happened just three weeks ago, the day after new years.
Luckily, my retina is still intact. So now I'm waiting a year to get the stitches out of my cornea, and then we'll see what shape it's in and if it's possible to improve my sight with a hard contact lense.
What happened to yours and what's the status?
Damn.. I'll be doing this next year. Bring on the pain..
How long can healing take ? I so don’t want a cornea transplant,,,,,,,,,,,
how are you now
very detail information has known after watching this video, thank you so much for such an excellent visual, understandable presentation..
I saw a G.
I've seen it all.
Dope describes my rhymes, making all you emcees cold drop like dimes. You know MCSC is back again, and battling me on the microphone is like committing a sin.

How about a natural way? Cannot afford medical treatment.
Amasing! This process of the conjunctiva growing into the cornea, is this called Pterygium? what is called?
Fantastic explanation! Great content in 3- minutes!
it's well done, but I wish it was not so sponsor-heavy. Nature publishes science mostly independent of industry - this sheds a dubious light on Nature's commitment to that idea
Hi. Thanks for your comment. Our sponsors don't have any input into our videos - all Nature Video content is editorially independent from sponsors/industry.
I don’t understand the English language so much, but in this video I could understand everything. Thank you
I have recurrent corneal ulcer and this is probably the fifth time since 2019 . It has also doubled in size but going to the doctors isn’t very helpful and putting eye drops are uncomfortable, some making it even worse
does nearsightedness get selfhealthed?
Wow perfect explanation
Can there be a permanent solution on keretoconus in future???i mean something to shape the cornea to normal and thicken it???????plz reply
I'm going through that 😢😢
When ppl faint ...does this happen....cuz it becomes cloudy ???
Let it be light 💡
Bottomline: protect your cornea.
i see you're a man of culture aswell.
Amazing video!
i hope a solution can be found
how to keep it healthy in the first place?
When the thing fell off the eye I screamed
Do finger does same thing?
