Hello and welcome back.
[0]
I am Dr. Rahil Chaudhary,
[1]
Eye Doctor, Cataract and Refractive Surgeon
[4]
Today we'll talk about Cataract
[8]
or Safed (white) Motiabind,
[11]
also commonly known as Motiabind.
[14]
Don't confuse it with Kala (Black) Motiabind.
[20]
Safed Motiabind (Cataract) and Kala Motiabind (Glaucoma)
[23]
are two different diseases.
[25]
Safed Motiabind (Cataract) means
[26]
the lens has turned white,
[29]
whereas Kala Motiabind (Glaucoma) means
[30]
increased pressure inside the eye.
[32]
Kala Motiabind is known as Glaucoma
[35]
and Safed Motiabind is known as Cataract.
[38]
Today we'll discuss about
[41]
Safed Motiabind or Cataract
[44]
Let us first understand what they are,
[50]
whether you need to be worried about it,
[52]
what latest treatments exist,
[55]
what latest lens options you can have
[60]
that is used during the surgery,
[63]
and the cost for the lens.
[66]
We'll discuss these in today's video.
[68]
Let's get started.
[70]
Most importantly, let's not be scared about Cataract
[76]
Cataracts are very common
[81]
as you get older.
[84]
Just as hair turns grey with age,
[87]
when you grow older than 60 or 70 years,
[92]
the natural lens inside your eye
[96]
that is as clean and clear as a mirror
[105]
turns white when are older
[109]
that is known as Safed Motiabind
[112]
or Cataract.
[113]
It is not necessarily always age-related,
[116]
but most people get it as they grow older.
[120]
sometimes it can occur in young children,
[123]
in newborn infants,
[126]
due to certain medication,
[128]
due to diabetes or
[130]
due to an eye injury.
[133]
These may cause the lens to turn white.
[138]
These situations are rare;
[142]
for most people, it happens as they age.
[147]
Just as grey hair can come with age,
[149]
the lens can also turn white with age.
[153]
How can you identify a cataract?
[157]
If your lens gradually turns white in color
[163]
(first a faint white, then opaque),
[166]
The light entering the eye
[170]
is partially blocked due to this white layer.
[175]
and light is not able to reach the Retina properly
[179]
The symptoms that you first notice are:
[182]
you vision becomes blurred or hazy
[185]
changes in the prescription of your glasses,
[189]
particularly when driving at night
[193]
you see glare around headlights
[197]
(bright lights spread out too much)
[199]
or sometimes you experience double vision.
[202]
For example, if you are looking at the moon, you may see two moons.
[205]
If you notice any such symptoms and
[208]
if you are above 60 years of age,
[212]
there's a high change that
[214]
you may have Cataract.
[216]
Please consult with your doctor.
[219]
For cataracts, it's important to note that
[224]
the only treatment option available for Cataracts
[230]
is an eye operation
[232]
During a Cataract Operation,
[235]
the natural lens that has become white & clouded is removed
[239]
and replaced with a new artificial lens.
[243]
With the new lens
[245]
light easily passes through and
[248]
vision gets back to normal.
[251]
It may seem quite simple, but
[253]
nowadays, the cataract surgery and artificial lens used
[261]
both have seen many advancements and changes.
[265]
The artificial lenses used today
[268]
are designed in such a way that after the operation,
[272]
there is no need to wear eyeglasses.
[275]
These days, we combine Cataract surgery with a Refractive Surgery
[280]
in such a way, that
[281]
the operation can remove both cataracts and need for power glasses.
[286]
Through this video, I'll explain
[290]
the various techniques for cataract operation available today
[293]
the types of lens available
[296]
and their approximate cost.
[298]
I'll explain this one by one.
[301]
"How exactly a cataract operation is performed?"
[304]
I have already created a detailed video on that
[309]
To watch that video,
[311]
please click the link above.
[316]
It explains which tests must be done
[318]
before the cataract operation and
[321]
the procedure for the cataract operation.
[323]
Latest Cataract surgeries done today
[330]
don't involve stitches or pain.
[335]
The entire surgery is done using numbing eye drops.
[340]
There are no stitches, no pain, no injections or no issues;
[344]
the entire surgery is performed using only numbing eye drops.
[347]
Hence, the patient doesn't feel any pain during surgery.
[350]
There are three categories of cataract operations.
[358]
Let me first explain how the cataract (cloudy lens) is removed?
[364]
The cloudy lens (cataract) can be removed by 3 types of operations
[368]
and there are 4 categories of artificial lenses inserted in the eye after removing the cloudy lens.
[375]
I'll explain this in detail.
[377]
First, the basic operation done today in Delhi,
[382]
(Earlier we had operations like SICS, ECCE
[386]
but nowadays they're no longer popular
[388]
in big cities like Delhi
[390]
because they involve making a large incision.)
[392]
Modern methods use microscopes and small incisions
[396]
The first type of operation is MICS
[400]
(Micro Incision Cataract Surgery).
[404]
MICS is a minimum standard now
[408]
We don't prefer surgeries older surgeries
[410]
MICS involves three machines.
[414]
One is the Centurion machine, the latest,
[417]
along with an Optical biometer
[419]
which is used to calculate lens power
[422]
and a high-end display microscope.
[424]
In Delhi this is a basic-level surgery,
[429]
but the majority don't opt for this.
[432]
It has lost popularity since the advent of Laser cataract surgery.
[436]
Next type of surgery is Zepto surgery.
[441]
As you can also see here,
[444]
hard cataracts or mature cataracts
[449]
that look either white or black
[452]
are removed with Zepto Laser Technology.
[458]
This surgery is only for a few people.
[461]
Doctors usually suggest
[464]
to not let a cataract mature.
[466]
Earlier, doctors would suggest waiting for cataracts to be mature before getting operated
[476]
Why would they say that?
[478]
Because the older concept of cataract was
[481]
that the lens that has turned white
[484]
must first completely mature.
[487]
Then doctors would make a large incision
[491]
to extract the entire lens as is
[494]
and insert a new one in its place.
[496]
Doctors today don't recommend this
[498]
due to the large incision that it needed
[501]
which must then be closed
[502]
with six to seven stitches.
[503]
Modern operations are stitch-free.
[506]
Methods used are microscope and laser
[510]
However, there is one condition, to be eligible for modern surgeries
[512]
that cataract should not be hard/matured.
[516]
If the cataract matures, it hardens.
[521]
The harder it is, the more laser is used to break it
[526]
which can eventually harm eye tissue.
[531]
The latest guidelines and understanding
[535]
are that the cataract must not mature;
[538]
it must be extracted when fresh,
[541]
as soon as you start having difficulty
[544]
with your daily activities.
[547]
For example, working on a computer,
[549]
or a housewife unable to do her chores.
[553]
When it starts to affect your daily work,
[556]
get the surgery done.
[559]
However, these are also losing popularity;
[564]
The most popular cataract surgery today is
[568]
Femto Laser with Artificial Intelligence.
[571]
This latest technology won't require
[573]
eye glass after surgery.
[576]
I have made a detailed video about this.
[580]
This procedure uses six machines
[587]
(the sixth is not in this picture).
[591]
With the help of these six machines, the surgery is performed in such a way
[595]
(with guidance from Artificial Intelligence)
[598]
that, the surgery causes No Pain
[600]
It includes No Injections,
[602]
No Stitches
[604]
No Blades,
[605]
No Bandages
[606]
No need for hospitalization.
[609]
If you get operated on today,
[610]
you have your vision tomorrow onwards.
[611]
With some restrictions for a week,
[613]
such as not letting water touch the eye,
[615]
or avoiding dust,
[616]
you are free thereafter.
[619]
The techniques discussed so far
[621]
are used to remove cataracts.
[623]
When the cloudy lens (cataract) is extracted
[626]
it is obvious that when the natural lens turned white
[630]
and remove it
[631]
another lens must take its place.
[634]
which will help you see clearly.
[636]
For the lens that will be inserted,
[639]
its quality, design and power
[643]
can be customized.
[645]
We use a lens that will
[647]
eliminate the need for eyeglasses.
[651]
The first type of lens used is called
[654]
Monofocal lens.
[655]
Monofocal lens corrects distance vision.
[660]
For example, driving, watching a movie,
[662]
television or site-seeing, etc.
[664]
It's all clear.
[665]
But for any near sight work,
[669]
you will need eyeglasses.
[672]
For example, if you work on a computer,
[675]
use your mobile phone
[676]
or any mid-distance work
[680]
you will need eyeglasses.
[682]
Monofocal lenses are not so popular these days.
[685]
Many companies manufacture them,
[687]
but the quality is similar;
[689]
they all provide good vision.
[691]
Imported lenses from U.S. or Germany
[694]
are obviously slightly better
[696]
because of their design and quality.
[700]
However, Indian lenses are also now high quality.
[703]
Monofocal lens has one standard lens
[707]
named AcrySof IQ.
[708]
Alcon's AcrySof IQ is the best
[713]
which will solve the problem for good.
[716]
The second type of lens is called
[720]
Monofocal with depth of focus.
[724]
95% of patient are operated using
[728]
Monofocal with depth of focus lens.
[731]
It provides clear far vision
[735]
(such as driving or watching a movie),
[738]
and clear intermediate (mid-distance) vision
[740]
(using a computer, laptop or mobile).
[744]
But for near sight work
[746]
such as reading, writing or studying,
[747]
eyeglasses are required.
[749]
It has two lenses regarded as high quality:
[755]
Tecnis Eyhance and Alcon Vivity lens.
[762]
The highlighted portion here
[765]
shows what doctors mostly use.
[767]
The third type of lens is Toric.
[770]
Let's understand about this one.
[773]
A human eye has two sets of optical numbers;
[779]
these are spherical and cylindrical.
[784]
If you only have a spherical number,
[788]
Monofocal with depth of focus lens is used.
[791]
If you have both
[793]
spherical and cylindrical number
[795]
a Toric lens is used.
[797]
Toric lens corrects cylindrical number
[801]
and improves better vision.
[803]
Toric lens is available in Monofocal and
[808]
Monofocal with depth of focus too.
[811]
Monofocal Toric is cheaper compared to
[815]
Monofocal with depth of focus Toric.
[818]
What is the best lens in Toric?
[824]
If you opt for Monofocal Toric then
[827]
AcrySof IQ by Alcon is the best.
[832]
If you opt for
[833]
Monofocal with depth of focus toric
[837]
Vivity lens by Alcon is the best.
[841]
Alcon Vivity Toric lens is now the best.
[844]
It is the most recommended lens
[846]
all over the world,
[848]
with great and amazing results.
[854]
The fourth type of lens is
[858]
Multifocal lenses.
[859]
This gives you clear vision for
[863]
far, mid and near distance.
[869]
It may seem that Multifocal lenses are best
[874]
as they solve all vision problems.
[878]
But there is a drawback in these lenses
[883]
known as halos and glares.
[886]
This means that at if you go out at night
[890]
such as for driving or traveling,
[892]
you may experience the spreading of light
[896]
or you may see rings/flares around the lights.
[898]
Because this can be quite uncomfortable,
[904]
Multifocal lenses are mostly not advisable.
[911]
Exceptions are housewives or retired people
[915]
with minimal activities
[918]
may be suggested Multifocal lenses.
[920]
Multifocal lenses are used for less than 1% of all patients.
[924]
Multifocal lenses are also expensive,
[927]
due to the cost and drawbacks
[930]
doctor's mostly don't advise this.
[932]
Less then 1% patient might be suggested
[936]
for Multifocal lens.
[937]
95% of patients are operated with
[942]
Monofocal with depth of focus or
[945]
Monofocal with depth of focus Toric.
[948]
Toric resolves the cylindrical number.
[950]
There can be no end to cataract discussions,
[957]
because it is a very common problem.
[960]
But you should know the latest cure
[964]
and the latest lenses available
[966]
to give you best vision.
[967]
Now if I conclude this video
[970]
and you ask which the best lens is
[974]
with the best techology and results,
[983]
I would suggest
[985]
Femto Laser with Artificial Intelligence.
[988]
Yes, we now have AI surgery too!
[990]
Simple Femto laser is done throughout India
[993]
but the add-on of Artificial Intelligence to Femto Laser
[996]
that has made our surgery results much better.
[998]
Femto Laser with Artificial Intelligence is best
[1001]
and if you don't have cylinder number
[1004]
then opt for Monofocal with depth of focus.
[1006]
If you have cylinder number then opt for
[1008]
Monofocal with depth of focus with Toric.
[1011]
Best lens for Monofocal with depth of focus
[1014]
is Alcon Vivity
[1015]
and the best lens for
[1016]
Monofocal with depth of focus with Toric
[1018]
is Alcon Vivity Toric.
[1019]
These are the latest and best treatments.
[1023]
Please leave any doubts or questions in the comments.
[1027]
Cataract is a broad topic
[1029]
that can't be discussed in 10-15 minutes video.
[1032]
The purpose of this video
[1035]
is to give you an overall idea
[1037]
about the technology and lenses available for cataract treatment
[1040]
which will help you to be prepared
[1043]
so you can ask your doctor
[1046]
and take an informed decision.
[1049]
Thank you very much
[1050]
for watching this video
[1051]
and I will be back soon.
