A method for ipsilateral rotational autokeratoplasty.

Rotational ipsilateral penetrating autokeratoplasty is useful in the treatment of certain nonprogressive corneal scars. The procedure alleviates difficulties with the availability of donor tissue and with graft rejection. A method is presented for determining the maximum clear central corneal area that can be obtained by rotational autokeratoplasty and the most appropriate trephine size and placement. Two dimensions must be obtained either at the slit lamp or from photographs: the diameter of the largest circle of clear cornea and the shortest distance from the edge of this circle (edge of the scar) to the center of the cornea. An illustrative case is presented.
