      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 !!! 🙂

    • @optometrywithkhurram6867
      @optometrywithkhurram6867  Год назад +1

      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.

    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

      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.
