Intraoperative head drift and eye movement: two under addressed challenges during cataract surgery.

ABSTRACT: PURPOSE:To objectively measure head drift during cataract surgery, and subjectively simulate eye movements and assess impact on surgical technique. MATERIALS AND METHODS:Twelve consecutively recorded routine cataract operations in the Tennent Institute of Ophthalmology, Gartnavel General Hospital, Glasgow, were reviewed. The speculum was used as a fixed point and correlated with a superimposed virtual ruler to measure maximum head drift in each direction throughout the operations. To simulate intraoperative eye movement, we attached string to the cataract surgical simulator (Eyesi) eye and manually induced abduction and adduction. A calibrated scale secured to the Eyesi head ensured 5 mm eye movements were consistently created. Ophthalmology trainees performed the continuous curvilinear ca
