Simplified system of marking the cornea for a toric intraocular lens
Received 19 February 2009; received in revised form 23 March 2009; accepted 24 April 2009.
A 2-instrument set comprising a half-circle axis marker and a degree gauge that facilitates precise placement of ink marks on the cornea is described. Guiding the half-circle axis marker by the previously positioned degree gauge ensures placement of the marks on the astigmatic axis line that transects the center of the cornea and overlies the index marks on the toric intraocular lens.
