Subjective Refraction

[@SuwindaDishan]

JCC is used to define cylinder axis. And we can use Dialing technique using rotate the cylindical power inward and out ward 15° rotation

[@m.a4491]

Best explanation on KZbin 👍👍👍

[@OptometryAcademy]

Thank you 😊

[@otiebrown9999]

Good presentation. I now make this measurement objectively, using my Snellen and Test Lenses. This is my path to recover my naked eye 20/20 vision - objectively!

[@najamulhassan192]

It made me more clear ,, kindly share a video on B scan ..

[@saharukhalam4974]

You tell the step by step process, and I understand very good.... Thanks.... You explain all of point... That's clear to understand...🙂🙂🙂😍🥰🤩

[@OptometryAcademy]

Thank you 🙂

[@mercy-constanceaturu7030]

Does it mean that as long as there is an astigmatic power, the patient cannot get to a 6/6 while adjusting the spherical component at the beginning until we refine both the cyl axis and cyl power?

[@jundonchannel8956]

good explanation, this is good for students for learning

[@otiebrown9999]

When I measure my refractive state myself, it is an objective scientific measurement. Never subjective. Your measurements are subjective.

[@sereezemoiselle3270]

Jcc is the answer.. well explained. thank you

[@OptometryAcademy]

Thank you 😊

[@sadhananavale7100]

Thank you that you share important knowledge 🤝🤝🤝🤝

[@optometrywithkhurram6867]

Good effort.. 👍👍

[@SuwindaDishan]

How about using minus cylindical lenses?

[@mohammadabrarshaikh3928]

JCC

[@ashwiniashu647]

Tqq so much sir waiting for more videos about eye

[@OptometryAcademy]

Thank you 😊

[@mercy-constanceaturu7030]

Aren't we supposed to rotate the axis towards the red (minus) side of the JCC?

[@RolaAbdaljalil]

please explain if we use minus cylinder

[@drankushsawalkar8631]

There mention step of subjective refraction ? Yes or No ? 🙏plz tell

[@medicalstudent_optom]

JCC is the answer. Thank you sir🙏

[@OptometryAcademy]

Thank you 😊

Sir class super

[@gowsikam1153]

Well explained 👏👏👏👏

[@OptometryAcademy]

Thank you so much 😊❤️

[@thilakraj4241]

May I know why should we rotate cyl lens towards green side of jcc??

[@ayyixx24]

why not using cc dots sir? please explain

[@نورالهدى-ب4ظ3ظ]

Thank you so mush👍🏻👍🏻👍🏻

[@rameshkumarca]

Very good 👍👍👍

[@OptometryAcademy]

Thank you sir ☺️

[@drmcwisdomsnwankwo5289]

thank you so much for your concise lecture. when refining the cylinder power, you mentioned adding a +0.25DS to the existing Sphere. Is that correct? or you meant adding a 0.25DC lens to the exiting Cylinder power.

[@ao6157]

He meant adding a 0.25 DC to the existing cylindrical power because it is refining the cylindrical power, not the spherical power

[@srushtipatil8122]

Well explained thank you 🤗

[@OptometryAcademy]

Thank you 😊

[@poonampriya3314]

Superb Ans is jcc

[@Lily-dw2dw]

[@sachinsharma787]

Sir please make a vedio of presbyopic refraction in detail

[@OptometryAcademy]

Ok sir😊

[@RameshKumar-cw1mm]

Clearly explained 👌

[@OptometryAcademy]

Thank you ☺️

[@AleezaOptoA]

Thanks so much It is very helpful for me

[@OptometryAcademy]

Thank you 😊

[@shirazshaddad6158]

When we want to refine the cylinder axis and power by JCC we rotate the cylinder lens axis towerd the red axis of jcc or green one ??? I am confused

[@OptometryAcademy]

For this, please watch my video on JCC. kzbin.info/www/bejne/nn7YpJR_q7l_jNE

[@beingartisticmom9995]

Jcc is the answer thank you sir

[@OptometryAcademy]

Thank you 😊

[@dipperlo5140]

sir，do we always do pinhole test without correction？ and is always the VAsc with pinhole the same or almost the same with the BCVA of sub refraction?

[@OptometryAcademy]

Not always, but if there is decrease in vision, then we do pinhole test to know the visual potential of the eye. BCVA after refraction may be same or almost same as vision with pinhole.

[@dipperlo5140]

Optometry Academy got it，thx a lot

[@OptometryAcademy]

😊

[@ROBINHOOD-lp5os]

Can i use Add +1.0 , + 0.25 in myopic cases mean same mothed or differ? thank you.

[@ROBINHOOD-lp5os]

In binoculer balanced

[@OptometryAcademy]

Same method.

[@ROBINHOOD-lp5os]

.thank you very much . How i can test child with nystagmus in both eyes congenital nystagmus .horizantl .

[@VedaHandigol]

Thank u sir

[@DigvijayKumar-k7z]

all good thanks for sharing

[@PoojaSharma-yg5qg]

Answer is JCC Lovely

[@tejalpandit7527]

Hi sir , binocular vision test karte samay agar patient bole double dikhta hai to kya kare

[@ROBINHOOD-lp5os]

Add +0.25 to sph or cyl in binoculer balanced test ? Thank you

[@OptometryAcademy]

Sphere

[@hinditoontv4319]

Loved it 👌

[@sunandamaity9657]

Of course JCC😊

[@RohitKumar-tr4wp]

JCC

[@dipperlo5140]

sir,have u considered posting a video about the diagnostic refracting? For example,a patient has problems with his optic nerve,and he comes to check his BCVA,what more exams can we do or should we do apart from sc/cc,pinhole and sub/obj ref ?

[@airam33]

you need to check the colour vision, check RAPD for any pupillary deffect .

[@gowsikam1153]

Jackson cross cylinder

[@narendraprasad8345]

Corneal topography?... Video?...

[@SanaKhan-yw7iz]

Thnx sir...

[@OptometryAcademy]

😊

[@srushtipatil8122]

But cylinder value always in minus???

[@muntazirhayat6321]

Esa kuch nhi hai

[@samadhanshinde2735]

Good

[@kaustubhmanidevvanshi7962]

Stenopic slit

[@azzamalyafie6573]

We need Jacson Cross Cylinder

[@azzamalyafie6573]

And the handle of the JCC should be parallel to the axis of the cylinder frame

[@dr.pavaneeswarreddy8039]

Nice

[@OptometryAcademy]

Thank you so much 😊

[@sorinvalea9249]

Still, Can't understant why you do some steps...it's too difficult

[@hinditoontv4319]

Jcc

[@sewanymichaels8813]

You are wrong where u said you move towards green no you more toward red

[@mercy-constanceaturu7030]

Ans: JCC

[@mercy-constanceaturu7030]

Why didn't he refract to 6/6 at the beginning?

[@sososwsw711]

👍👍❤

[@indiancaptain2372]

Plzzzz uploade this video in hindi
