Because lag may vary with accommodative demand, 9, 25 this study used normalized measurements. Lag was measured at three retinoscope distances (33 cm; 50 cm; 67 cm), giving three different points on the accommodative demand-response curve (targets rotated

A recent study from China has shown that children with a lower amplitude of accommodation showed a better myopia control response to orthokeratology over two years, indicating that improving accommodative function may be part of the mechanism. 14 Measurin

Assessing accommodative function, such as measuring near lag of accomodation, is a vital component of understanding the myopia profile of your patient. Myopic progression in children and adults can be influenced by binocular vision function. There is a re
