title: Axis measurement strip for Haag-Streit BM900 series slitlamp.
abstract: We describe a technique to measure the toric IOL axis using an axis measurement strip applied to the Haag-Streit BM900 series slitlamp. The technique was used by 3 surgeons to determine the postoperative toric IOL position in 47 eyes, and these data were compared with objective measurements derived from images made with a Galilei G2 corneal analyzer. The results indicate that the axis measurement strip provides a precise, clinically efficient measurement of toric IOL position.
