so why do eye doctors do LASIK eye surgery if they haven't gotten it themselves oh
that is a good question
hey this is dr. allen here from the doctor eye health show the channel helps to
learn all about the eyes vision and finding the best vision product so if we
knew here to the channel and like learn about the eyes then hit that subscribe
button down below so that you don't miss any of my future videos now this video
is kind of special we're actually be talking really answering some of the
questions that you and other viewers have asked on across all the different
videos that I've made and so yeah we're gonna try to answer some of them here
okay Aphrodite yeah it's me I like that name so Aphrodite do I have to clean my
contact lenses every day even when I'm not wearing it I use bi-weekly contact
lenses so yes when you are using contact lenses and you clean them disinfect them
usually if you read the back of the bottle of whatever disinfecting solution
you're using it'll actually say how long you can still leave your contact lenses
in that solution so read the box whatever you're using I know I think
optically pure moisture which is that I usually use ought to double check but I
believe it says you can use that up to thirty days George Soros asks can you
make a video about CRT orthokeratology, absolutely I'm hoping to actually
make a video on that but I'm actually trying to loop in another doctor friend
of mine who fits a lot of orthokeratology lenses and being that
you know I fit a lot of them but he fits just even ten times more than I do so I
think it'd be kind of cool just to have another guest on the show and talk a
little bit more there but yes orthokeratology lens if you're someone
who's never heard of that they are fantastic it's kind of like an
alternative to LASIK so that you can actually wear contact lenses at
nighttime and they actually morph the surface of your eye and actually the
next day you take out the lenses and so you're walking around the day without
contact lenses in and you can see great but then toward the end of the evening
the surface of the eye kind of reshapes back to its normal shape so things get a
little fuzzy and then you just again put the contact lens in overnight and you
repeat the process and it's an excellent alternative for a lot of people is that
true that you can clear the scratches on the glasses using toothpaste
honestly I personally don't know that this actually works I have
tried using toothpaste to clean like CDs and stuff like that and I don't think it
works at all no I probably guess not fabiola asks can you make a video
explaining about different types of retinal vein occlusions well the answer
to that is yes I hope to make a video about that at some point however I'm not
sure how many people are specifically looking for that but I think it would be
a really interesting video a retinal vein occlusion is at the most basic
level a stroke in the back of the eye most commonly from elevated high blood
pressure so this like people think of a stroke happening in your brain and
causing a lot of problems potentially even death and that actually a stroke
can happen in the back of the eye as well usually an eye doctor will see
something as a branch retinal vein occlusion that's where a single branch
of a vein basically gets kind of clogged up because of the way the artery is
crossing over the vein and that causes a backup of pressure and it causes the
vein to burst leading to blood and fluid building up inside the eye and that can
actually cause the retina to swell and that swelling of fluid can actually
cause damage to the retina even more serious is something called a central
retinal vein occlusion that's basically where the entire central vein going to
the eye gets blocked up and that actually ends up with a lot of blood in
the back of the eye we actually call it blood and thunder and this is actually
lead to not only decreased vision could actually put a great risk of developing
a very serious type of glaucoma so whenever we see this in the clinic we
have to act fast but yes fabiola of course I will make that video for you at
some point it may take me a little bit to get to it but yes that would be a
really interesting video basic point for everybody who's seeing this if you have
high blood pressure taking medications and try whatever you can to change your
lifestyle so you can decrease that blood pressure don't want to be getting a
stroke in your eye so why do i doctors do LASIK eye surgery if they haven't
gotten it themselves oh that is a good question first of all when it comes to
LASIK there is kind of a lot you need to understand when an eye doctor see
somebody for LASIK even another eye doctor we have to consider one are they
a good candidate because of the power of their eye and I personally do fit into
that I can get LASIK too we have to see if their cornea the surface of your eye
is thick enough that again thankfully my cornea is thick enough per the power of
my prescription so I'm a good candidate for that reason but number three is
really motivation and is somebody who's going to have an evaluation before
having LASIK eye surgery are there expectations with the surgery in the
realm of realism and that's something that a lot of people have trouble with
they go in to have a lazy evaluation and they think that you know LASIK will just
be this miracle cure for them that they'll be able to see better than 20/20
and that's not realistic at the same time some people think I'll get LASIK
and that I'll never never need glasses of contact again that is also not true
for multiple reasons one LASIK can only get your vision as clear as like your
glasses and contact lens prescription will get you so if you're somebody with
a lazy eye like amblyopia that's more of a cortical thing going on in the brain
and less a problem with this really the correction of the eye so yeah they can
correct it so maybe you're not as from you know they don't have to rely on
glasses as much but you're still not gonna see quite as sharp as an eye that
doesn't have like a lazy eye when it comes to someone like myself I really
I'm just at the personality I have just requires to have really sharp vision all
the time if I'm not seeing 20/15 I'm like irritated by it and knowing that with
LASIK eye surgery they usually on most times can get people to see 20/20 a lot
of the time but they can't guarantee they're gonna get you to see 20/15 which
is something that I'm already seeing with glasses and contacts so for that
reason I don't think I would be super happy getting LASIK on top of that one
of the more common complications from LASIK eye surgery is more of a dry eye
sensation and I already have at least some level of dryness on my eyes so to
take that risk of going through getting LASIK to not see as good as I do with
contacts and then have my eyes even more dry than they already are it's just not
worth it but at least when it comes to LASIK for
myself and other eye doctors I know that a lot of adopters have had LASIK and
they love it they really do enjoy it there are some doctors who like
myself have not had LASIK and it could be either for the reason that I just
said like I'm I know that I'm not the best candidate for that procedure or it
could be because I know one of my one of my other actually one of my mentors in
school she said you know I've seen that less than 1% of people that have had
complications and she just doesn't want to take that risk
it is a little bit of a gamble there's truth with any sort of surgery that
things can go wrong it's very rare like very very rare with
LASIK but there are some people who have bad outcomes so that is a kind of a risk
that your eye surgeon will discuss with you if you're willing to take that very
very small risk ok Canadian kid asks can you do your own PD measurement and why
do most optometrists not include that with their eye exam this is actually a
really good question we're actually discussing this at my own clinic the
other week a PD measurement is your pupillary distance between one people
and the other and is generally used for corrective lenses when prescribing
glasses it's actually you know historically it used to be part of an
examination because kind of opticals used to be one-stop shop so you see the
doctor they fit with glasses and that includes the PD measurement and then
they make you glasses now these days there's a larger separation between what
I care professionals do in the actual medical clinic versus what's sold in the
optical versus glasses so there's like the separation between glasses and
medicine where it used to be all kind of intertwined so a lot of doctors now we
don't measure the PD during the examination because there's really no
point it's not useful for us to figure out what's healthy for your eyes and
what the right correction is that's something that really depends on the
glasses you're getting and what type of glasses you're getting if you're
somebody who's just getting reading glasses then the PD measurement your
people are a distance measurement is different than if you're just looking in
the distance and it also depends on little micro things yes there are ways
that you can measure your own PD or people at a distance again at home
whether you're using just kind of a ruler a centimeter ruler and look in the
mirror there's certain guides online actually I should make probably a video
on that there but there's also some different
some things like that out there that you could use in general though when you go
to see an optician they don't just measure it with a ruler or sending me a
ruler if you're really into a specific optical it takes things seriously they
actually have a machine or a pupa lammeter that will measure not just
where your pupil is on one right eye and then compared to your left it actually
measures them individually because most people's eyes aren't perfectly equal
distance with their nose in between they're actually a little bit more to
the right a little bit more to the left so you may have one that's like thirty
four millimeters on the right side and like thirty one millimeters on the left
side and that'll change where your glasses are sitting and if they're not
sitting the right way then that'll throw off the whole prescription so yeah if
you were looking to get really exact measurements then yes go see an optical
question of the day what other questions do you have please go ahead and comment
in the section below or if you have any other video ideas of
topics you'd like to see me cover I do have this long list of videos that I'm
