    This is the best video ! Accent and r sound is little irritating but it's so informative that I ignored it mine is also not perfect and sometimes my own accent irritates me and hence I improved upon my accent and pronunciations and still Improving but thanks it's very very informative such practical really useful things we were not taught by our consultants and were taunted,irritated for theoretical non sense and insignificant stuff, useless consultants absolutely useless and irritating ! Thanks for giving us the right accurate information thats actually practically very very significant amd useful ! Awesome video I am gonna share this video link 🔗 🖇️ on my revision part along with elkington audio book I am gonna make on my youtube channel !

    Excellent madam, it is very clear for me now, 0.5 for power and 0.25 for axis. I will do this way. Thank you.

    Single best reference for JCC. Thank you ma'am! I do have a doubt, though, ma'am. At 6:48, If we are adding the SE to the sphere component, why is there a change in the cylindrical value since we have already accounted for that with the SE?

    I was trying to explain that if the cylinder change (by using JCC) is greater than or equal to 0.5, then you change the value of the sphere. In the example shown, the original prescription was -2.00 / -1.00 x 180. So the spherical equivalent becomes -2.50. If we add a -0.50 (because of JCC) to the cylinder, we get -2.00 / -1.50 x 180. Now the spherical equivalent is -2.75. so we add half the cylinder change of opposite sign to the sphere - so since we added a cylinder of -0.50, (to -1.00 to make it -1.50), we should add +0.25 to the sphere - so adding this to the sphere of -2.00, we get -1.75 / -1.50 x 180. The spherical equivalent of this is -2.50, which is the same as our original prescription (prior to JCC testing)

    Mam ..this is ok ..but when I do JCC .if the patient with - cyl after flipping JCC , pt reports red line is more clear, then theoretically we add minus power .right? But whether we done it practically it's not confirming the power ..y?

    Hii mam while refining the axis of cyl if patient say minus side is better why should we trun around the minus axis .why we can't rotate towards the plus axis .

    @prasannashetty2526 , In the example given in the video, the cylinder was rotated in the direction of the minus axis of the Jackson cross cylinder becoz the cylinder in the trial frame was a minus cylinder. If the cylinder in the trial frame was a plus cylinder, then it should be rotated towards the plus axis of the Jackson cross cylinder
