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?

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.
