Sph = sphere; Cyl = cylinder; Bias = retinoscopy measurement − Retinomax measurement, computed using vector methods¹³; VDD = vector dioptric difference¹³ (absolute value of the vector dioptric deviation between Retinomax representative and retinoscopy measurements, taking into account sphere, cylinder, and axis, calculated after mean bias was subtracted from retinoscopy measurements).
