biometric study of ocular changes during accommodation for preoperative assessment of intraocular lens power

A biometric study using A-mode ultrasonography was performed on 45 eyes with and without ocular accommodation. During accommodation, an increased Lt and decreased anterior chamber death [ACD] were noted in group I only. The axial length was not significantly changed during accommodation or after the offset of any accommodative effect. It was concluded that axial length [AL] measurement performed on a dilated pupil can give an accurate result that was not statistically different than those obtained without papillary dilatation
