- This video is about the optical cross in retinoscopy.
The gross and net retinoscopy.
How can we find only spherical form in optical cross of retinoscopy
how can we find only cylindrical form in optical cross of retinoscopy.
He is a Good Optometrist & uses super techniques to teach others... Any optician who watching his videos can be a good Optometrist, if he or she follows these teacher's techniques. 😍
Thankyou 🌸
Thank you sir , you are helping so many future aspiring Optometrist ❤❤
You are welcome 🙏🏻
Very helpful I've finally gotten to understand optical crosses, thanks a lot
Goodluck
Your teaching style is very clear to us thnks sir
Helpful ❤
But you didn't deduct cycloplegic allowance in case 1?
I think there is no need to deduct allowance of drugs when you didn’t even instil the drops.
@@optometrywithkhurram6867
Okay 🙃
I was confused a bit when you didn't deduct it, but in case 2, you did...
So, you should mention for more clarification that in case 1, cycloplegic drops aren't used, while in case 2, they are used...
Overall you delivered a great lecture Sir !!! 🙂
@@muazurrahmansalfi thankyou

🌸
great
Thankful to you Sir🙂
Very helpful thank you sir 👍🏻👍🏻
Excellent sir.. thank you
Most welcome
Cyclopentolate ciliary tone value has 0.75
Sir apny Plus ma 1.50 working distance nikla cyclopentolate nh 0.50 add nh kia minus ma 1.50 k sath 0.50 cyclopentolate add kia aesa q ? Jab k dono ma plus oe minus dono ka 1.50 working and 0.50 Cyclopenlate ka nikala hota hai its mean total 2.00 apni ek 1.50 k retinoscopy ki ek 2.00 p???¿
Jis case me cyclo use he nahi kia us me deduct q krna hai..and jis me use kia hai us case me deduct krna hai
Very very clear Sir!! Well done!
Is there any technique to confirm the answer we have done calculation right or not? I heard about something transposition etc
i will explain in a video.
Thanks sir very helpful video 🙏🙏
All the best
superb explanation
Thanks for liking
Thanks sir
Sir why wasn't cyclopentolate value deducted from the 1st hyperopic example?
Because we didn't use cyclopentolate drops..then no need to deduct.
When we will instil the drops when we will deduct cyclopentolate value and working distance both.
@@optometrywithkhurram6867 You didn't differentiate the two cases as with and without cyclopentolate.
In myopia no need to substract cyclo effect cose there is no accomodation????
Sir A small doubt we want know about optitech retinoscope as we want to buy that
It's very knowledgeable sir thanks 🙏🙏
Welcome
Great explainanation sir
🌸🌸
Thanks
Wow great 😊😊👍👍
Thankyou
So when the streek is verical and you neutralize it with +4 , it means that you put +4 on the power cross at 90. Right?
When the streak is vertical... actually u are neutralizing horizontal meredian....and when the streak is horizontal u are neutralizing vertical meridian.
Tq sir
Sir how can we prescribe prism lens with power, kindly discuss about these type of case also.
Dear sir
Should we not always consider the smaller value as the sphere ??
Means in hyperopic case you also picked smaller value as sphere n greater value as cyl , but in case of myopic example you used greater value as the sphere not the smaller (value)one
It's not necessary dear..you can choose both..smaller or greater..both are fine..but smaller value is good as sphere..as you said.
@@optometrywithkhurram6867
Thnx much Respected dear sir💖
@@mayaarish6267 your semester and name ?
Sir
It's Maya Arish n I'm done with all semesters
N currently practicing 💫
Optometry with Shaista and this channel is an amazing waho
tonic allownce for cyclopen is 0.75
explain about multifocal contact lens sir
Doing my Research on these multifocals contact lenses...noted..soon will upload.
Can please tell us in plus and minus combination in optical cross section
ua-cam.com/video/hATGFH5QZl4/v-deo.html
Sir I heard that we select least value as sperical
Both are correct..it's not necessary to take the least value as spherical or greater value as spherical..both are fine
Hi can you do an example for oblique cyls? Thank you
👌👌👌
Pateint female left eye Ar reading0.25 cyl right ,light ko dekha to achanak adhera aa jata he kyu .
Nice sir
Sir cyclopentolate give about +0.75
👍👍👍👍👍👍👍
-6.00 Dsph with +1.0 cyl 180
Or
-5.00 dsph with -1.0 cyl 90
But sir between axis..???
Hlo sir ,second case jo hai sir samjh nhi aaya 🙏
It's too easy to understand..which portion you didn't understand..dear?? Let me know I'll explain.
Very helpful 👍
Sir we use tonus allowance of cyclopentolate?
Yes..and tonus allounce of cyclopentolate is 0.50.
@@optometrywithkhurram6867 sir tonus allowance of cyclopentolate is 0.75D .
0.5D for homatrophine.
@@Iqss....1187 Yes..in different books value is different..so dn worry you can put o.75 or o.5..not a big deal.
@@optometrywithkhurram6867 okay thank you.
How much
How to do this?
Calculate the combined effect of the following
sphero-cylinders
+3.00/-2.00 x 45 and -4.00/+1.00 x 110
+1.00/+2.00*135
-3.00/-1.00*20
Cyclopentolate tonusallowence +0.75 Ds
It's different according to different authors..some books write 0.50 and for some it's 0.75
No least one is selected as cyl and more power is sph
Cyclopentolate ka -0.75 ho gaya sir..
Cylindrical in second example should be minus 1????
Sir Y u didn't deduct tonus allowance in ist case.plz reply
Working distance was 1.50 D and for cyclopentolate dioptric allounce is 0.50 so total is 2.00D ....which is deducted from working distance. Watch carefully again.
Sir hindi main samjhayega
Hindi me explain kariye sir
