Splitting of the lens inner nuclei. Splitting of the lens inner nuclei. Following coring and peeling, the resulting lens nuclei were split in half using two pairs of EM grade forceps. The lens is gently grasped from the anterior and posterior with the tines parallel to one of the Y-suture arms (A). Each pair of forceps is externally rotated, splitting the lens through the optic axis (B). The resulting halves reveal the surfaces of the embryonic and inner fetal nuclear fibers, permitting the measurement process (C; adapted from [1]).
