okay today we're going to be seeing if
it's possible to actually use a laser to
shine it on your cornea and reshape your
cornea so you can actually see better
and so in order to show you this I
actually underwent real LASIK eye
surgery and filmed it in the operating
room so you could see what's actually
happening to my eye during LASIK eye
surgery so let me show you what's going
to happen during the operation okay so
to show you how this works first I'll
perform my own LASIK eye surgery on this
eye here which is actually an egg and
then I'll show you the performance of a
real surgeon on my real eye in the
operating room so I have the actual
instruments that I asked the surgeon if
I could keep from my own surgery so
here's what happens so first they stick
this thing on your eye and it has kind
of a suction cup on it and it's going to
go right over your iris like that and
then they put you in a different chair
and this piece is hooked to a machine
that has a laser on it and this piece
has to dock together so basically your
eye is it your eye is on it like this
and this piece comes over and they dock
it down and it has to fit right in there
and this piece has a hard glass lens on
it right here and so this is going to
dock into here and it's going to get
pushed right up against your eye and
they suction it against your eye like
this well it sucks the eye right up in
there against the lens so it does apply
some pressure to it it doesn't hurt
because they put numbing drops in but
basically this lens is pressed up
against your eye
and now here's where the they create a
corneal flap and so it's called a laser
microtome it's a femtosecond laser and
it shoots the laser light right down in
the middle there and it's focused just
under the outer layer of your cornea and
what happens is right where it's focused
it creates a plasma right underneath the
outer layer of your cornea and it
creates tiny little plasma bubbles so
this laser starts shooting and it
rasters up and down and up and down and
goes across your eye and so it separates
a tiny little corneal flap and that's
the flap that the surgeon is then going
to flip up so let's create my corneal
flap with my high-strength laser here
three
to one so after they do that the cornea
is now foggy because there's this layer
of gas in between there and then this is
the cool part then the surgeon comes in
and grabs that flap with a better tool
than what I have here and then pills it
up and now this is the part that
actually shapes your cornea so at this
point he moves me to another machine and
has me look up at a light and he tells
me to watch that light and this is a
special kind of laser it's an
ultraviolet laser and it tracks my pupil
so even if you shift your eye a little
bit it's always tracking it and what it
does is it vaporizes the part of your
eye that needs to be reshaped and so it
reshapes your cornea so it can focus the
light better so as you're looking up
this ultraviolet laser which you can't
see comes down and it starts itching
your eye away and it makes this buzzing
sound and as its itching you can
actually kind of smell the I getting
etched away which it was a little bit
weird and that only takes a few seconds
and then the surgeon gently puts down
the and that only takes a few seconds
and then the surgeon gently puts down
the corneal flap smooths it down and
then your eye begins to heal on its own
and that flap will reseal within like
six hours they said and so the flap
seals down and it basically has a
natural band-aid on it to start healing
your eye okay now that you saw how it
worked on an a guy let's see what it
looks like on my actual eyes so let's
check out my real LASIK eye surgery
filmed so first I met with the eye
surgeon dr. Cornell and asked him a few
questions about the procedure okay holy
cow here we go about to go into the oh
are you operated on
okay so first they put in the numbing
drops here and I've got a little stress
ball here for you okay I just read that
instead okay we are ahead cover up your
left eye go ahead close both eyes dr.
Cornell
and now as I'm laying down they're
putting those suction cups on my eye
okay
[Music]
and then they're gonna swing me over to
the other chair and then they put me
over under the machine and now they're
docking it against my eye now this part
was the most uncomfortable part this is
the part where because of the pressure
that's on your eye it actually makes
your eye kind of black out and you can
actually mimic this if you just kind of
push on the side of your eye if you do
that for a long time eventually your
vision will just kind of black out
that's because you're cutting off the
circulation to your eye so it's not
getting the blood flow and knees to
create that vision so now they have
these two pieces docked together and
this lens is against my eye squished up
against my eye so you can see the laser
form this plasma underneath the thin
layer of my cornea here and so it turns
Y as it forms this plasma underneath and
it goes up and down and up and down so
basically basically you just see this
white move across my pupil now for the
other eye and the left eye okay I kind
of the red line
[Music]
okay thank you now at this point
help me up and it's just the foggy I
can't really see anything because I have
this kind of gap under my cornea now
that's filled with I guess gases there's
a making it a little bit foggy and so
then I moved to the different laser and
this is the laser that has the waveguide
that actually shapes my cornea now this
is the cool part this is where the
surgeon has to get in there and pull
that corneal flap up so during this I
didn't actually know what he was doing
at this point I just kind of felt
pressure on my eye it's really cool to
see afterwards what's happening
[Music]
dr. Cornel was amazing amazingly smooth
hands you can see that little tiny very
thin flap getting pulled up
[Music]
and this is a part where you can smell
the vaporizing cornea
[Music]
and then he puts the cornea flap back
down in flow
[Music]
now the other eye
[Music]
football's a good idea and a great idea
let you speak you're going something
like this
Dadu it's actually not that bad the
worst part was them that beginning
Venice I almost just rubbed my eyes just
that okay see if I check it right yes
let's take a picture here document this
okay and guess what I'm not wearing no
more contacts and glasses
well give him a thumbs up you did okay
so the reason I did this I was actually
planning on getting LASIK already and
just the date before my surgery I called
him and I asked if it'd be okay if I
filmed it cuz I thought it'd be really
cool to see the actual eye surgery and I
thought you guys would like it and sure
enough they said sure it's great if you
film it and so they actually did it for
me for free and they said if I just put
a link in my description if anybody's
been thinking about LASIK surgery check
out the link in my description LASIK
plus is a great option it was I love the
staff here everything went really well
so check it out if you're thinking about
it or if you've been curious about it
check out my description I'll put a link
there for a discount if you want and
then after all that's done they eat your
eye
oh no they don't nevermind so I'm about
four days post-surgery now and I can see
almost perfectly clearly now it's a
little cloudy but it takes a few weeks
to clear up it takes a few weeks for the
fluid that got between that flap and
everything and your eye being inflamed
from the laser takes a few weeks for
that to go away completely but as of now
it's like I'm wearing glasses hey
