Accommodation Amplitude and Lag Study in<br />

Relation to Different Variables<br />

Prof. R Maheshwari, Dr. Ankita Phougat, Prof. R R Sukul<br />

To evaluate amplitude (AA) and lag (AL) of accommodation with respect to<br />

ametropia, emmetropia and amblyopia.<br />

To study lens thickness (LT), anterior chamber depth (ACD) and axial length<br />

(AxL) changes during accommodation.<br />

Accommodation is the process by which vertebrate eye changes refractive<br />

power to maintain a clear image (focus) of an object as its distance from eye<br />

changes. The word accommodation was given by Burrow (1841). 1 The functional<br />

significance of active accommodation is evident from the inconvenience that<br />

results from its gradual age-related loss in presbyopia, manifests earliest in<br />
